In this lesson, we learned about biogeochemical cycles & Human Impact on the Environment. Firstly, we learned about the water cycle which starts with the evaporation of water then the water condensates to form clouds then the cloud undergoes precipitation. Precipitates has 4 forms which are rain, snow, sleet and hail. After precipitation, transpiration follows which is the absorption of water of plants then infiltration is next where the water is absorbed by the soil then surface runoff occurs where water that isn't absorbed by the plants flow in the ground. After the water cycle, we learned about the nitrogen cycle which is more active than thunderstorms. The nitrogen comes in the atmosphere and called as atmospheric nitrogen then gets absorbed by the soil and can get into the roots of the plant root after a nitrogen-fixing bacteria living in the legume root nodules or after getting absorbed by the soil, nitrogen fixing bacteria makes the nitrogen into ammonium then a nitrifying bacteria makes the ammonium to nitrates(NO₂)by the process of nitrification then a nitrifying bacteria again makes it nitrates (NO₃) then it either goes to denitrifying bacteria to atmosphere or it gets in the process of assimilation to the plants then goes to the decomposer to make it into ammonium or the plant is eaten by an animal then decomposes by the decomposer then is transferred into ammonium. After that, we learned about oxygen and carbon dioxide cycle. We learned that both of this cannot exist without each other because oxygen is produced by plants using carbon dioxide and organisms inhale oxygen and turns it into oxygen or by human activity-producing carbon like burning fossil fuels. After these, we learned the four main effects of human activities in the ecosystem which are; air pollution due to burning of fossil fuels; water pollution due to wrong garbage disposal; deforestation due to excessive cutting of trees; coral reef destruction due to the illegal fishing and many more. For this lesson, I rate myself and the topic and Ma'am EJ since I learned a lot and understood in very good.

We learned about ecosystem & trophic levels. I learned that only plants are the only producers since they are an autotrophs meaning they can produce their foods by themselves. They can convert the energy from the sun into chemical energy and form the glucose which is their food in the process called photosynthesis which uses water, carbon dioxide and sunlight. Excess glucose is converted into starch by the plants and is stored in the roots, stem, leaves, tuber, seeds, or in fruits. Most of the photosynthesis happen in day. Since humans and other animals are not capable of producing their own food, they depend on plats or organisms that is considered as a producers. Those who eats the producers are called the second-order consumer then if an organism ate a second-order consumer, it is called the third-consumer. Then there's this called scavengers that is an consumers that look for and eat dead animals or plants. One the scavengers are done eating the dead organism, the decomposers take over and consume whatever was left by scavengers. The transfer of energy from one organism to another is not 100%, the amount of energy available at each successive level is called trophic level. There's a way to explain the order of consumers and its by using food chain but if you will try to explain how will the organisms eat each other in a biome, you can use the food web. For this lesson, I rate myself 5/5 also Ma'am EJ and the lesson because I had fun and learned a lot.

In this week, we learned about hierarchal taxonomic system we also learned about the classification of organisms and early taxonomists. We learned many things and this is what I learned. First, there are systems that was made that starts from broad to more specific. It starts from kingdom to phylum to class to order to family to genus to species. Second, In the classification of organisms, classification is the arrangement of organisms into orderly groups based on their similarities and known as taxonomy. Third, Taxonomists are the scientist that identifies and names organisms. Fourth, I learned about the early taxonomists and I learned that Aristotle was the first taxonomist 2000 years ago and he divided organisms into plants & animals by their habitat then Carolus Linnaeus followed in the 18th century and he classified organisms by their structures and what he developed are still being used until today. He is also known as the "Father of Taxonomy" and developed binomial nomenclature which is the Two-word name with the combination of the Genus & Species name. Fifth, binomial nomenclature used Latin or Greek names and Italicized if is type written and Genus name of the organism should be capitalized but not species and if written, it should be underlined with the genus name being capitalized. Sixth, we learned about domains. There are three domains which are the archaea, Bacteria (prokaryotes) and Eukarya (Eukaryotes) which are more complex. The archaea was probably first to evolve because it can live in harsh environments and its kingdom is archaebacteria. The bacteria is found in all of the habitats except the harsh one and is an important decomposers for environment and commercially important in making yogurt, cottage cheese, etc. The domain bacteria has the kingdom Eubacteria. The Domain Eukarya is divided into kingdoms which are; Protista which are mostly unicellular and some are the opposite, some are autotrophic while some are the opposite also and is heterotrophic; Fungi which are multicellular except yeast and an absorptive heterotrophs and its cell walls are made of chitin; Plantae which are multicellular, autotrophic and its cell walls are made of cellulose; Animalia which are multicellular, ingestive heterotrophs and feeds on plants or animals. Seventh, I learned that most genera contain a number of similar species and classification is based on evolutionary relationships and called as Taxons. Lastly, Cladogram which shows the shared and derived characteristices of organisms. For this lesson, I rate my self and the topic and Ma'am EJ since I learned a lot and I understood it pretty well.

We learned another interesting Biology lesson for the 3rd Week of the 4th Quarter. What we learned was all about the classification of organisms or taxonomy. In this topic, we learned how organisms are arranged in orderly groups. The scientists that identify and name organisms are called taxonomists. To summarize what we learned during the discussion, we were able to know the benefits resulted by classifying (e.g., it prevents misnomers), the scientists who have contributions to taxonomy (e.g., Carolus Linnaeus, and Carl Woese), the hierarchy of groups or taxa (domain, kingdom, phylum, class, order, family, Genus, and species), and the cladogram (shows how organisms are related). Among all of these parts that we tackled during the discussion, my favorite part was when we were taught about the hierarchy of groups or texa. It is probably because there were many interesting concepts explained in this part. Even though there were many concepts explained, all of them were easy and fun to understand. In taxonomy, there are three domains which are Archea, Bacteria, and Eukarya. Following these are the different kingdoms, phylum, class, order, family, Genus, and then species. I think that I was somehow able to fully understand or master this week's lesson. The YouTube video that our teacher presented at the beginning of the session was a great help as it gave me insights before properly tackling our lesson. For this week, I would rate myself 5/5.

In this week of the 4th quarter, there was no synchronous session that occurred for our section. As a result, I tried to study the lesson with the use of the module provided to us. I was able to understand many concepts, however, I think that there were still some parts or terms that are a bit confusing.

For the second week of the 4th Quarter, our teacher discussed mainly about cell division. I think that this lesson was quite complicated at first. However, I was able to learn about the concepts properly with the help of our teacher's explanation and presentation. For the summary of what I learned, I learned about the levels of organizations, life stages of humans, the cell increase and cell decrease (mitosis, cytokinesis, and apoptosis), the cell cycle, the stages of interphase (G1 stage, S stage, and G2 stage),  the checkpoints of the cell cycle, and more about Meiosis and Mitosis. Among all of these concepts, my favorite part was about the process of cell division or nuclear division. Specifically, the part involving prophase, metaphase, anaphase, and telophase. This was my favorite because it was interesting to know the different stages or phases that the cell goes through in order for the division to occur. In prophase, the chromosomes which are thick and short are visible. Spindle fibers are also formed in this part. During metaphase, the chromosomes are lined up at the metaphase plate. The sister chromatids are also attached to the spindle fibers which were formed during prophase. During anaphase, the spindle fibers pull sister chromatids/chromosomes toward the opposite poles of the cells. Lastly, the chromosomes are already at the opposite poles during telophase. The spindle fibers also disappear at this part. Cytokinesis also happens in which the cytoplasm is going to be divided. Our teacher did a bit of simulation to illustrate the process of PMAT in cell division. This way, it was quite easier for me to understand and observe what happens in cell division. For this week, I would rate myself 5/5.

In the first week of the 4th quarter, we started learning about Biology. Specifically, we discussed the Human Digestive System. We were able to learn about different terms and concepts relevant to the functions of the digestive system (ingestion, digestion, absorption, assimilation, and egestion), the organs of digestion (alimentary tract and accessory organs), and the two types of digestion (mechanical and chemical). During the discussion, some terms were already familiar and I think it is probably because we already tackled a bit of this lesson from our previous school level/s. Among all of these concepts that I learned during the discussion, my favorite part was about the organs of digestion which are divided into two main parts. These parts are the organs of the alimentary tract and the accessory organs. This is my favorite part since it gives me an overview of the characteristics of the digestive organs and it also gives me knowledge about their significance or functions in our body. This part also gives me a further idea of how the food is being digested in our bodies. The alimentary tract or gastrointestinal tract consists of organs from the mouth to the anus. It particularly consists of the mouth, pharynx, esophagus, stomach, small intestine, large intestine, rectum, and anus. Meanwhile, the accessory organs —which are associated with the alimentary tract, consists of the salivary glands, liver, gallbladder, and pancreas. Under this part of the lesson, I was able to learn additional terms that are important for understanding the particular organ. These terms are the bolus, peristalsis, rugae, chyme, sphincter muscles, and other more. I believe that I was able to properly understand these concepts with the help of our teacher's explanation and the presentation which includes illustrations of the organs. The GIFs or the short clips that were provided in the presentation also helped me to understand how a certain process works. For instance, I was able to clearly learn how the pharynx serves as a passageway for digestion and respiration with the help of some illustrations. This week's lesson was engaging and interesting for me. With this, I would like to rate myself 5/5 for this week of the 4th quarter.

In this week, we discussed mainly about the cell cycle. But before Ma'am EJ discussed the cell cycle, we started off learning about the Biological Levels of Organization. Since it was already discussed when we were grade 7, we did not focus on it too much. After that, we proceeded on learning on the life stages of human on which we start as an infant, grow to be a child, enter the adolescent and adulthood stage, and become an elderly. After those opening topics, we ma'am EJ started to talk about the cell cycle which starts with the G1 phase where the cell doubles its organelles and accumulates materials for DNA synthesis, then enters the S phase where DNA synthesis occurs, then proceeds to G2 phase where cells synthesizes proteins that are needed for cell division and lastly, enters the M phase where the cell divides. After that, cell division was tackled where we learned that, all cells came from a pre-existing cells, cells are produced for growth and repair, and the cell division differs when it comes to prokaryotes and eukaryotes because the prokaryotes cell division takes faster due to the fact that it only undergoes binary fission than how the eukaryotes finishes cell division. We learned that when cells divide, the new cell or also called as the daughter cell is identical to the parent cell and that is due to DNA which is responsible for holding the instructions for making cell parts and a complete DNA in a new cell is important for another cell division. After that, we learned that chromosome, if duplicated, are called chromatids and are held together by centromere. Chromosomes are also made up of coiled DNA. We also have learned that cells increases in number but their size does not, somatic cells increases by mitosis, gametes or sex cells increases by meiosis, cells decreases by apoptosis or programmed cell death, and cytoplasm division which is Cytokinesis. Then after these topics, we discussed the mitotic stage which follows the interphase. we learned that during mitosis, sister chromatids of each chromosome separates and becomes a nuclei of the two daughter cells, and the cell cycle ends after the cytokinesis is complete. We also learned about the check points between G1 phase and S phase, between G2 phase and M phase, and M phase prior to the end of mitosis. Mitosis also have stages. It starts with interphase where the cells duplicates everything, then prophase follows where the chromosome splits into chromatids, then Metaphase where the chromosome lines up in the center then the spindle fiber holds them, then anaphase proceeds where the spindle fiber breaks the chromosome, then telophase happens where both ends of the ell have the chromosomes and organelles then lastly, cytokinesis happens where the cytoplasm in the center of the cell divides. After we learned about the mitotic stage, we learned about meiosis and we learned that meiosis ensures that the next generation of cell will have the diploid number of chromosome, and a combination of traits that differs from that of either parents. The meiosis have two parts; meiosis 1 where daughter cells are haploid and no replication of DNA occurs, and meiosis 2 where the sister chromatids separates and the daughter cell becomes a haploid daughter cell. In Meiosis 1, the Prophase 1, Metaphase 1, Anaphase 1, Telophase 1, and interkinesis happens. After that, the meiosis 2 where prophase 2, metaphase 2, Anaphase 2, Telophase 2, and cytokinesis happens. After discussing the meiosis and mitosis, we tackled the human life cycle further. We learned that in males, meiosis occurs as spermatogenesis and produces sperm while in females, meiosis occurs as oogenesis and produces egg cells. The mitosis is involved in the growth of a child and repair of tissue during life. When the sperm and egg cell combines, since both have haploid number of chromosome, will become a diploid number cell and becomes a new life. After all these topics, ma'am EJ summarized all the topics she had discussed. For this topic, I think I mastered this enough to say that I rate my self as 5/5 and I also rate ma'am EJ 5/5 and also the topic 5/5 since I learned and enjoyed a lot.

In this week, Ma'am EJ taught us about the functions of digestive system, types of digestion, and the part of the digestive system. Supposedly, we were having a second part of discussion but due to some technical problems, we were unable to have the second part of the discussion. In the functions of digestive system, what we learned is that there are five functions. First, Ingestion which is the process of taking in food through the mouth. Second, Digestion which is the process of breaking up food into smaller soluble pieces. Third, Absorption which is the process of the digested food goes into the bloodstream to the cells. Fourth, Assimilation which is the process where the digested food products moves into the cells where it is used. And lastly, Egestion which is the process of getting rid the solid waste outside the body. In the types of digestion, we learned that there are two types which are; Mechanical digestion where it involves the chewing, grinding, tearing, mushing, and mixing of food into smaller pieces and Chemical where it involves enzymes to breakdown macromolecules to small organic molecules. And lastly for the parts of the human digestive system, we have learned that it is divided into two; The alimentary tract which consists of the mouth, pharynx, esophagus, stomach, small and large intestine, rectum, and anus; The accessory organs which includes the salivary glands, liver, gallbladder, and pancreas. We also have learned in the parts of the human digestive system that; Mouth is the starting point of the human digestive system, it is also called as oral cavity and contains the following: teeth for breaking down the food into smaller pieces, Tongue that mixes food with the saliva, Salivary glands that secretes saliva, and the palate forms the roof of the mouth. The next part is the pharynx which is also called the throat. It is the passageway of the respiration and the bolus. Bolus is the food that is broken down into smaller pieces and mixed with saliva. During also the swallowing, the sphincter muscles relax and raises the epiglottis to cover the traches pushing the bolus to the esophagus. The next part is the esophagus. The esophagus is a muscular tube which food passes from pharynx to the stomach. It is also where the peristalsis is observed. Peristalsis is a wave like motion that prevents the food from flowing backwards. The next part is the stomach. Stomach is a muscular, elastic, pear shaped organ and its function is that is stores the swallowed food, mixes the food with the digestive food, and conveys contents so small intestines. The contents that are transported to the small intestine is called chyme. There are also the muscles that prevents the chyme from going up. It is called the Esophageal sphincter muscle and the Pyloric sphincter muscle that allows the chyme from going down the small intestine. The stomach also contains the rugae that folds in the interior of the stomach. The stomach also contains mucus secreting cells that produces alkaline mucus that protects the stomach from stress and corroding effects, Parietal cells which is hydrochloric acid, Chief cells which is protein-digesting enzyme, and G-cells or also known as gastrin cells. The next part is the small intestine. It is also called as organs of complete digestion and absorption. It also has three parts, The duodenum (shortest and most fixed), jejunum (freely-movable portion), and the ileum (longest and highly coiled). It also contains the villi that is responsible for the nutrient absorption. The next part is the large intestine. Its function is it temporarily stored fecal materials, absorbs vitamins, and reabsorbs the water from the undigested residue. For the next part, it is called the salivary glands. It has a mucus part that produces the saliva and also has a serous part that contains salivary amylase ptyalin that digests carbohydrates in the mouth. For the accessory organs, The liver is responsible for carrying out the production of bile from bilirubin and the gallbladder secretes the bile. Bile is responsible also from emulsification of fats, and neutralization of chyme. Gallbladder is also a part of accessory organs. For the last part of the accessory organs, the pancreas. Pancreas functions as both endocrine and exocrine gland. The endocrine part of the pancreas secretes hormones ion the metabolism of sugar and the exocrine part of he pancreas secretes amylopsin, trypsin, steapsin, and nuclease. For this lesson, I rate my self as 5/5 since I understood this lesson properly and I rate Ma'am EJ and this topic also 5/5 since I learned many things and enjoyed it.

Our lesson this week focused on the periodic trends. We talked about the electron affinity, electronegativity, ionization energy which all of them increase from left to right and bottom to top. While the atomic radius and metallic character increases from right to left and top to bottom. I'd say my favorite trend or arrangement would be the ionization energy and I would give myself a 5/5 since I had learned it pretty easily. :>

# data[].attributes.body
We learned about the history of the periodic table and some of the periodic trends. My favorite part of the lesson was when we were introduced to these trends which are the ionization energy and atomic radius. Although I was still getting a bit confused to the elements, I enjoyed learning it so I give myself a 5/5.

# data[].attributes.body
Since our topic is broad, we had two synchronous classes this week. This week was the most enjoyable week of the quarter in my opinion. It's because I learned something new, and our recitations were incredibly fun. We explored the periodic trends of atomic radius, ionization energy, electronegativity, electron affinity, and metallic property this week, and we learned how to arrange elements based on those periodic trends. We were also able to arrange elements more easily because you provided a periodic table of elements with trend labels.  I had a stronger relation this week than the other weeks, and I think I did very well both in terms of listening to our discussion, participating in our recitations, and completing our tasks. I would give myself five out of five for this week because I enjoyed both sessions because of our recitations.

Week 7 made me nervous because we'll be talking about the periodic table of elements, which is something I'm afraid of. You, on the other hand, fortunately introduced us to the history of it, which I find interesting. In this week's session, you introduced us to Johann Dobereiner, John Newlands, Dmitri Mendeleev, Henry Mosely, and, last but not least, Glenn Seaborg, who were all engaged in the creation of the periodic table of elements. After going through the history of the periodic table, we moved on to the parts of the periodic table. Periods are the horizontal rows, and groups are the vertical rows. Metals, nonmetals, and metalloids are the three classes of elements. We were able to remember our understanding of the periodic table by going back and discussing it. So, for this week, I'd give myself a five-out-of-five rating because I'd say it gave me a lot of new information, helped me remember what I already knew, and made me nervous, all of which made this week's session enjoyable.

# data[].attributes.body
Matter is made up of atoms that are composed of protons, neutrons, and electrons and that was our topic in this week's session. This session made me fully understand the concept behind the subatomic particles. We also did computations for this week's session which had me confused at first but after doing the tasks given to us for this week, I now get it. In the center of the atom is where we can find the nucleus and in the nucleus, we can spot the protons and neutrons but not the electrons because it is located at the electron orbits. I also learned in this session that the mass of the protons and neutrons in the atom's nucleus is expressed in Atomic Mass Unit (amu). I would rate myself four out of five for this week because I know that even if I couldn't actively participate in our discussion, I did my very best to listen and understand our topic fully.

# data[].attributes.body
Because we switched our asynchronous and synchronous classes, I recall that we had a pre-activity to prepare for the week's topic. So you gave us an asynchronous task for our Monday class, which was supposed to be our synchronous session, in which we had to watch two videos and answer the guide questions. We became prepared to answer the game or quiz that you created for us, which was about the history of the atom, as a result of this task. As far as I recall, I was one of the top ten people who would receive an incentive, and I was overjoyed. Then we explored the history of the atom in our discussion. I gained a lot of knowledge from our discussion. Their atomic models are the most memorable and favorite part of this session because, while I was first unclear about what they contributed, their atomic models helped me remember their contributions and who proposed those many theories. For this session, I would give myself a three out of five since I believe I did my best to listen to our discussion in order to better understand our topic even if my connection was really bad to the point that I couldn't actively participate in our recitations. After all, I was initially confused, but thanks to our discussion, I now have a clear understanding of that.

# data[].attributes.body
This week's session felt short. It's because all we have to do in this session is talk about evidence of chemical reactions. Five evidences were discussed. But, of course, to really understand it, you first explained how we can tell if a chemical reaction has occurred. We recalled that physical change does not result in the creation of a new substance, whereas chemical change does so by rearranging atoms. You also taught us about the Law of Conservation of Mass, which states that no mass is created or destroyed during a chemical reaction. Now, here are the five chemical reaction evidences that we discussed: The evolution of light or heat comes first. Then, temperature changes to the surroundings whether it increases or decreases. The formation of gas other than boiling, such as bubbling or an odor, follows. Fourth, a change in color as a result of the formation of a new substance. Finally, the reaction of two aqueous solutions results in the formation of a precipitate. You discussed it by providing us examples so that we could better understand our subject. In this week's session, I'd give myself a four out of five since, even though I didn't take part in any of the recitations, I can honestly say that I listened attentively to our discussion.

# data[].attributes.body
In this week, Ma'am discussed about the trends in periodic table. electron affinity and electronegativity increases from left to right and bottom to top in the periodic table. Ionization energy increases from right to left and top to bottom in the periodic table. Metallic property increases from left to right and bottom to top in the periodic table. This lesson is so fun so I'll rate myself 5/5.

# data[].attributes.body
In this week, I didn't attend the session so I need to ask my classmates what Ma'am EJ discussed. The History of Periodic Table, Parts of Periodic Table and Periodic Trends. First is the history of periodic table. In this topic I'll rate myself 2/5 since I didn't attend our class here but there are things that I have learned.

# data[].attributes.body
In this week, we tackled about atoms and sub-atomic particles. Ma'am discussed the difference between molecule and atoms. She also discussed that atoms are the smallest possible unit and made up sub-atomic particles. These sub-atomic particles are protons, electrons and neutrons. Proton is the positively charged particles. Electrons are the negatively charged particles and neutrons is a subatomic particle of about the same mass as a proton but without an electric charge. In this lesson, I'll rate myself 5/5.

# data[].attributes.body
In this week, Ma'am EJ discussed the History of the Atom. We tackled here the theories and models. Democritus. He named the atom. Dalton. Dalton made a model called Dalton's Atomic Theory. This theory proved that all elements are composed of tiny indivisible particles and it is the atoms. Thomson. He made a Chocolate Cookie Model where the dough part was the positive charge and the chips of chocolates are negative charge particles. He used the cathode ray tube to experiment the negatively charged particle, the electron. Rutherford. He made the gold foil experiment where he discovered the nucleus and protons. He said that the atoms are made of empty space but didn't know about neutrons. There are many more theories of atoms has but I will not enumerate all those theories. In this lesson, I'll rate myself 3/5 since it's a bit confusing for me and a little bit hard to memorize the theories and those who made that theory.

# data[].attributes.body
In this week, Ma'am EJ discussed about chemical reaction. It is on of my favorite topics because it shows how chemical reaction happens and there are evidences too like formation of bubbles, change in color, odor change, temperature change, formation of precipitate and other more. Chemical reaction is a process where chemical reacts with another chemical and create different substance. In this topic, I'll rate myself 5/5.

This week is the last week for third quarter so I am quite hype. Although we had two classes for this session for the reason that it was pretty long. Both sessions were also held in the afternoon and I really consider afternoon classes as boring because that is the sleepy hours but, for the first time I was completely awake. I think it was because I really enjoyed learning about periodic trends. So we first had a recall and then we immediately proceed to the lesson proper which were electronegativity, metallic character and electron affinity. Electronegativity increases from left to right and going up of the periodic table, same goes with electron affinity. While for metallic character, it was completely opposite. It increases from right to left and going down. Every trend we discussed, we had some drill as a practice. Through the help of learning the past trends, arranging elements in this session was quite easy for me. I was able to recite too. However, there are still times that I got the wrong answers. I sometimes arranged them wrong because of confusion and also the fact that I struggles a lot on finding the element and even recognizing their symbols so I guess I need to improved my skills in terms of that.

If will rate myself in this session, I'll give it a 4/5. Although I was completely awake, I was pretty distracted for some personal reasons and also from the poor internet connection I had that time. But overall, it was an informative and enjoyable session.

# data[].attributes.body
This week, we focused on Electronegativity and Electron affinity for the first session and in the second session, we focused on Ionization energy and Metallic Property of an element. After those classes I finally understand the order of each trend. For this week, I will rate it a 5.

# data[].attributes.body
This week, the lesson is all about the history of the Periodic Table and the Periodic Trends. At first, the discussion didn’t really sink into my brain because im confused with the order of each trend but I somehow made it sink into my brain although im still confused about the order of each trend from decreasing to increasing. For this week, I will rate it a 5.

This session was all about the periodic table. First we have discussed about it's history. Through this lesson, we were introduced to the scientist who contributed in the making of the periodic table. First, Johann Dobereiner who introduced the concept of Triads, John Newlands about his Law of Octaves, Dmitri Mendeleev who is actually considered as "Father of Modern Periodic Table", Henry Mosely Who gave rise to the new periodic table and Glenn Seaborg that discovered new eight elements. Also period/series and group/family were reviewed to freshen our minds from the lessons last school year. Moreover, periodical table trends were taught too. We have tackled what is Ionization energy and atomic radius. Also how to arrange them from increasing to decreasing or vice versa. At first, I was kind confused. I was like why certain element is higher than other certain element if it was placed in the part where that trend increase in the periodic table. But, through practice that we had in the discussion, It has lessen my confusion and it improved my skills on arranging them rightly.

If I were rate myself, I’ll give it a 5/5. For the reason that, I really enjoyed the lesson to the point that I never got distracted no matter what. Also, I was also passionate of mastering how to arrange elements by ionization energy and atomic radius out of my confusion. Let’s also add the fact that learning periodic table’s history has driven my curiosity that’s lead me to listen attentively. And I believe that I also did great in terms of complying my requirements in related to this session.

This week we started the discussion through playing a game after that we discussed further into the different trends in the periodic table namely, electronegativity, metallic property, electron affinity, and inoization energy. It's fun doing the excercises we had while moving on with the discussion. I'm happy about the things I learned this week and I'll rate myself 5/5. I'll look forward into our lessons in the fourth grading period.

This week we tackled about the history of atom. We discussed about the different people that contributed in the periodic table as time passed by. We also learned about the newland's law of octaves which states that every 8th element in the periodic table has similiar properties. I learned that Dmitri Mendeleev is the so called Father of the Modern Periodic Table. Lastly we learned arranging and comparing elements based on their atomic radius through their location in the Periodic table. I rate myself 4/5 for learning a lot and having fun listening in the discussion I'm looking forward to our future lessons in enhanced science 8.

This week we have discussed the last 4 periodic trends which are the  electronegativity, ionization energy, electron affinity, and metallic character. Electron affinity is the tendency of an atom to accept an electron.  Helium has the mostelectron affinity. It's trend is going up and going right of the Periodic table. Next is the electronegativity it is the ability of an atom to attract electrons in Bond. Its trend is going up and going right. Since Noble gases tend not to form bonds they do not have electronegativity values so Fluorine is the most electronegative element. Next we have the Ionization energy, it is the least possible energy necessary to eliminate an electron from a gaseous atom at its ground state. Its trend is going up and going right. The Helium has the Most Ionization energy. Lastly we have the Metallic character it is how prepared an atom can
lose an electron. As an element becomes more metallic, it has the tendency to lose an electron. It the element becomes more
non-metallic it has the tendency to accept electrons. Its trend is  going down the periodic table and going left of the Periodic table. My favourite part of the lesson is about the metallic character as it's trend is the same as Atomic radius which I have already fully understand because we have already discussed it the other week. In this week I think I would rate myself between 4-5. I have fully understand the lesson but sometimes it is somehow confusing especially when the elements you are arranging are far from each other. This 3rd qurater was fun and I have learned a lot of things. In the first week we have discussed about the phases of Mater and their properties. In the 2nd week we have a review on Phase change and we have also discussed Elements, Compounds, and Mixtures. In the 3rd week we have discussed about Phase change and its different types. Then in the 4th week we have learned all about the evidences of Chemical reaction. In week 5 we have learned about History and Models of Atom. In week 6 we have learned about Atoms and its subatomic particles and lastly this Week 7-8 We have learned about the History of the Periodic table and the Periodic Table. I have learned a lot this 3rd Quarter and now that it has come to an end I look forward for the lesson we would be discussing this 4th Quarter.

In this week we have learned all about the History of Periodic table and We have also learned the periodic trend of atomic Radius. Aristotle first discovered 4 elements. In 1817 Johann Dobereiner discovered that the atomic weight of strontium is in
between the atomic weight of calcium and barium and he named this as triads, which means the atomic mass of the
of the third element is equal to the average of the first and second element. Then in 1864  John Newlands suggested that if elements are arrnaged in increasing atomic mass they can also be arranged by groups of eight, which he named law of Octaves. In 1869, Dmitri Mendeleev proposed his Periodic table. He suggested that elements are arranged not only by increasing atomic mass but also according to chemical periodicity. Mendeleev's Periodic table was published the same year but he left some space because he predicted that there are still undiscovered elements. In the same year Julian Meyer produced a Periodic table almost the as Mendeleev's, but only consists of 28 elements. Both Meyer and Mendeleev where credited as the proponent of the Periodic table but most of the cretid were given to Mendeleev as his was more accurate and the prediction of more elements. In 1914 Henry Moseley arranged the elements into increasing atomic number. The periodic we use today re arranged again based on the modern periodic law, which declares that atomic number are the periodic function of the elements’ physical and chemical properties.The periodic table is arranged in patterns illustrating most of their chemical properties, which is called Periodic trends. There are five periodic trends namely electronegativity, ionization energy, electron affinity, atomic radius, and metallic character. The columns are named as groups or families, and rows are called as periods or series.  Atomic radius is the distance between two nuclei of adjacent atoms of the same element and dividing the distance by 2. Its trend is  going down the periodic table and going left of the Periodic table.  My favourite part of this lesson is About the Periodic trends because the 1st periodic we discussed was easy to remember and it was very easy to understand. In this lesson I think I would rate myself 4 because although the lesson was easy I am a bit confused with the arrangement of the discovery of the Periodic table, that is why I would understand it more and I look forward for the continuation of our lesson.

We talked about subatomic particles this week. Protons, neutrons, and electrons are subatomic particles. The proton is positively charged, the electron is negatively charged, and the neutron is neutral. This discussion significantly increased my understanding of them. This week, I'll give myself a 4/5.

# data[].attributes.body
This week, we talked about the history of the atom. We first learned about Democritus, who discovered invisible particles in the world and named them "atomos". There were also other scientists who experimented and studied atoms to learn more about them. We also learned about various types of atomic models. This week, I'll give myself a 4/5.

# data[].attributes.body
This week, we talked about chemical reactions. We found that chemical change occurs when a new substance is added or created through atom rearrangement. We also went over the Law of Conservation of Mass and the five evidences of chemical reactions. This week, I'll give myself a 4/5.

# data[].attributes.body
this week is amazing, because we get to play a game using the element symbols in the periodic table, my favorite part is where we arrange the electron affinity and electronegativity and I was able to get a right answer. I would say I mastered the topic pretty, I would give myself a 5 out of 5

# data[].attributes.body
This week is our last week for the third quarter and next quarter we will be tackling about biology. Going back, we had two synchronous sessions this week in order for us to understand the lesson well. This week we continued discussing about the periodic trends. We discussed about arranging the elements based on periodic trend required. The five periodic trends we discussed are the Electronegativity, Ionization energy, Electron affinity, Atomic radius and Metallic Character. Electronegativity is the measure of an atom to attract and attach electrons to itself. Ionization energy is the least possible energy necessary to eliminate an electron from a gaseous atom at its ground state. Electron affinity is the tendency of an atom to accept an electron. Atomic radius is the calculated distance between two nuclei of adjacent atoms of the same element and dividing the distance by 2. Lastly, metallic character is defined as how prepared an atom can lose an electron. Ionization energy, electronegativity, and electron affinity have the same order in arranging the elements. It is from left to right and from bottom to the top. Whereas, the atomic radius and metallic character are the opposite. It is arranged from right to left and from top to the bottom. It is quite confusing but gladly through answering worksheets from the internet, I was able to master it.

Ma’am discussed the lesson so well and everyone was able to participate. I also enjoyed the game in our second session before we have a continuation about our lesson. Overall, I’ll rate myself 5/5 because I learned a lot this week and I was able to participate. I am looking forward to our last quarter. Thank you ma’am 

This week, our class was moved on Tuesday because of technical problems. We discussed about the history of the periodic table, parts of the periodic table and the periodic table trend. But first what is a periodic table? Periodic table is a table in which the elements are arranged in order of increasing atomic number. Elements with same property are in the same group, and the same number of electron shells are arranged in period. Now, let’s discuss about its history. Aristotle believed that there are four elements such as water, fire, air and Earth. We are also introduced to chemists who helped in arranging the periodic table. One of them is Dmitri Mendeleev who proposed the periodic law. He was the one who is credited because his work is more accurate.

We also discussed about the groups and periods in periodic table. Now, what are they? Groups are the column and elements who share the same properties are at the same column. While periods are the rows in periodic table and elements who have the same number of electron shells are at the same period. We also discussed about the periodic trends which is exciting for me. To be honest, I’m quite nervous at reciting in this part because I may be wrong and it is a bit confusing.

In conclusion, we discussed about periodic table, its history, and periodic trends. Overall, I’ll rate myself 5/5 because of my mastery in this lesson and I was able to participate. Thank you ma’am 

This week, we continued our session from last week and also had 2 meetings. We discussed about ionization energy, electronegativity, electron affinity, and metallic property in the periodic table of elements. We also learned how to arrange the elements based on the trends given above. I really like this lesson because compared to our previous lessons, it's actually simpler than it seems. The only thing I find difficult in this is looking for the elements. Usually, I sing the periodic table song to find it, or I look at the elements one by one. It's pretty time consuming. I struggled a bit with my submissions for this week since I was all over the place. I went from the hospital, to a relative's home, to the cemetery. It was a pretty stressful time for me, but the module served as some sort of a stress reliever. I'd rate myself 5/5 because I enjoyed the lesson and answering the module.

# data[].attributes.body
For this week, I am happy because I completely understand the lesson about the trends. For the reason that after the seventh week, Ma'am EJ gave the module and I was able to review the content of it. That's why, I didn't encounter any problem. What I've like the most was about arranging it from increasing order depends on the trend. It's kind of challenging for me because all of us were participating and it's kind of hard since we need to find the element name for us to arrange it correctly. Since in this week we do have 2 synchronous sessions, so for me. It is not hard for us to understand.

They were Ionization Energy, Electronegativity, Electron Affinity, and Metallic Property. I will rate myself 5/5 for the reason this is the topic I enjoyed the most in this quarter and it is so heart whelming since 3rd quarter is finally over.

# data[].attributes.body
In this week, we are meant to discuss about the chemist who proposed such things about the arrangement of elements. So far, what I've like the most was about the meaning of groups and period. For the reason that I know how to locate the elements by the given format. Not just by looking for it's element name. Because of that, I've missed our performance we had way back when I was in grade 7. That we sung the periodic table song.

Also, we overcome the trends on our synchronous classes. Ma'am EJ discussed about it. So, I will rate my self 5/5. Because the lesson was easy for me. And the discussion was well explained. That's why, it is proved how we actively participate on our recitation.

# data[].attributes.body
This week we discussed further about the three subatomic particles namely the protons neutrons and electrons. We also tackled about the mass number, atomic number, and how to get them together with the three subatomic particles. My favorite part of the lesson was learning how to solve for the missing given like getting the neutrons or the mass number and etc. For this week I rate myself 5/5 because I learned well and I am interested with how the lesson is going.

# data[].attributes.body
This week we discussed about atoms and further deepen our basic knowledge about it. First we discussed about the changes in the models of atom over time. The first person who proposed atoms is Democritus way back from 400bc he believed that everything is made up of tiny invisible particles and called it atomos. Dalton is the first one to wrote an atomic theory he assumed that atoms are indivisible and atoms of the same element ar identical which was later proved wrong. Dalton also proposed the billiard ball model but later evidences also proved it wrong. Next is J.J. Thomson's plum pudding he stated that the dough parts are positively charged and the chocolates are negatively charged. There are still other things that we tuckled and in this discussion I rate myself 4/5 I'm interested in our lesson but I get confused sometimes with the dates and names.

# data[].attributes.body
This week we discussed about chemical reaction. First we know that a chemical change has occurred when a new substance is added or created by rearrangement of atoms. We also tackled about the Law of Conservation of Mass which states that when a chemical reaction occurs, mass is neither created nor destroyed. To put it simply it has the same concept with energy in which energy does not disappear but transforms into another type of energy so matter is also transformed into a differrent type or kind. Lastly we discussed 5 evidences of chemical reaction namely evolution of light or heat, Temperature change, formation of a gas, color change, and formation of a precipitate. These are the evidences that can be observed in a chemical reaction. I rate myself 4/5 because I'm interested in the topic and still have more to learn.

# data[].attributes.body
For this week, we continued tackling the different trends in the periodic table. This includes electronegativity, electron affinity, ionization energy, and also metallic property. While for the atomic size or atomic radius, we have already tackled it last week. With the help of the discussions, we got to understand the differences between each periodic trend. Electronegativity is the ability of the atom to attract electrons; electron affinity is the tendency of an atom to accept an electron; ionization energy is the energy needed to remove an electron; metallic property is how prepared the atom for losing electrons; and lastly, atomic radius is the distance of the nucleus from the outermost orbital of the electron. Above all of what we did in our discussions, my favorite part was when we get to arrange the given elements based on a trend. This was my favorite part because I think that our teacher gives us a chance to exercise our knowledge of arranging the elements based on the trend. As a result, it becomes easier for us to arrange elements since we have practiced them many times. The way that our teacher discusses the concepts was engaging for us students, especially because everyone from the class has a chance to participate.

If I were to rate myself, I would give a 5/5 because I would say that I tried my best to listen, understand, and also participate in the discussion.  I find the lesson very interesting and somehow remarkable.

# data[].attributes.body
We studied more trends of the periodic table. First was electron affinity, It increases as it goes left to right and bottom to top. Helium (He) have the most electron affinity. Second was Electronegativity, It increases as it goes left to right and bottom to top just like electron affinity. But helium is not considered as the most electronegative element because noble gases don’t have electronegative values. Flourine (F) have the most electronegativity. On the next day, we then learned about ionization energy again then about Metallic property. Metallic property increases as it goes from right to left and top to bottom. Overall I rate the lesson 5 out of 5 because it was pretty easy and I have fun arranging the element in order by different trends. Im looking forward for the next quarter!

# data[].attributes.body
We further learned about the history of the periodic table and how it came as how we see it today. Also, there is the Dobereiner’s triads, Newland’s Law of Octaves, Dmitri Mendeleev aka “Father of the modern periodic table”. In the periodic table there is the horizontal rows called Periods or Series. Then, there is the vertical columns called Group or Family. Some trend of the periodic table that we learned this week was the atomic radius and the ionization energy. Atomic radius increases as it goes from right to left and top to bottom, meaning that Francium (Fr) have the biggest atomic radius in the periodic table. Meanwhile, in ionization energy, It increases as it goes from left to right and bottom to top, Meaning Helium (He) have the highest ionization energy in the periodic table. I rate the lesson 5 out of 5 because It was really easy to know the trends of the periodic table, although maybe I need more time getting used to the periodic table and the elements again.

# data[].attributes.body
In this session we've got some deeper knowledge about the Ionization energy, metallic property, electronegativity and electron affinity.  The Ionization Energy measures how tightly electrons are bound in an atom. Metallic Property is the ability of atoms to lose electrons. Electron Affinity is the tendency of an atom to accept an electron. Electronegativity is the ability of atom to attract electrons in bond.

I would rate myself 4/5 cause it's fun to learn all about the elements in the periodic table.

# data[].attributes.body
This week, we have two synchronous section so we can finish our lesson in the third quarter. In Tuesday, we learned about electronegativity and electron affinity while in Wednesday we had a recap in electron affinity and electronegativity and we discussed about metallic character. I think I can now easily find the elements in the periodic table and easily arrange the elements by the trends. So, I will rate myself a 5/5.

# data[].attributes.body
In week 7 we learned about the periodic table of elements, the history of it and the periodic trends. In the periodic trends we learned how to arrange the elements by atomic radius and ionization energy. Week 7 is fun because we had have more chance to recite. For me, it was a bit easy but I've had some difficulties because I can't easily find the elements in the periodic table but after a few numbers I got faster in finding the elements. I would rate myself a 4.5/5 because I still have some little difficulties in this lesson.

# data[].attributes.body
We have learned all about how to arrange the atomic radius, ionization energy, metallic property, electronegativity, electron affinity. The trend of ionization energy is increasing from left to right and bottom to top. For the trend of electronegativity it is increasing from left to right and bottom to top just like the ionization energy. Also the trend of non-metallic property and electron affinity is also the same with the trend of ionization energy. For the metallic property, atomic radius, the trend of them is increasing from right to left and top to bottom.

I would rate myself a 5 because I really enjoy the topic and it is easy to memorize.

# data[].attributes.body
For this one we had a recap about our topic last week especially when it comes to the ionization energy, but we discussed more, we talked about the arrangement of the metallic characteristics which increases from right to left and up to down, the electron affinity and electron negativity wherein if we base it on the periodic table it increases as we go left to right and down to up. My favorite part of this lesson is the activity on how we arrange each of them based on the given whether it is increasing and decreasing. I would rate mg learnings and interest on this lesson 5/5 because it was easy to undertand and the lesson were taught very well. Since week 7, this lesson has been in my field of interest and I’ve been wanting to learn more about it.

# data[].attributes.body
For week 7 we have a recap about the periodic table, the reason why it was made and created, its parts just like the periods and groups or family. We also discussed on how to arrange elements in increasing or decreasing order based on its ionization energy and atomic radius. My favorite part about this lesson is when we arrange each of the elements according to its increasing or decreasing atomic radius. I think I would rate my learning and interest about this lesson probably 4/5 because it was very easy and the teacher discussed and explain each bit very well which makes it easy to comprehend.

# data[].attributes.body
For week 6 I have learned about the part and subatomic particles of an Atom. Matter is made out of atoms which are the smallest possible unit which matter can be divided, these atoms are composed of 3 subatomic particles namely the protons which is positively charged and neutron which is neutral meaning it is neither positively charged nor negatively charged. This neutron and proton is found in the nucleus of the atom while electrons which is negatively charged are found in the outside the nucleus and orbits around the electron clouds. Moreover, we also discussed about the Atomic number which are the number of protons in the nucleus of an atom, Mass number which are the total number if protons and neutrons in the nucleus, you can compute this by just simply adding or combining the amount of neutrons and protons together. There are also different forces in an atom namely the gravitational force, electromagnetic force, strong force and weak force. Isotopes, these are atoms that have the same number of protons but have different amount of neutrons. Ions are charged particles that typically results from a loss or gain in electrons, this have two types namely the Anion which is negatively charged particle and Cation which is positively charged. There is also Atomic Symbol Notations, firstly is A which represents mass number and can be computed by adding  Z which represents the atomic number or number of protons in an atom, and N which represents the amount of neutrons, and lastly the letter X which symbolizes the Element’s symbol. We also discussed on how and to compute for each one, for example, when you get your answer for the atomic mass you should round it off to the nearest whole number, for the atomic number you can just simply copy the number of protons and electrons given because it is just equal to those subatomic particles. And lastly to get the value of neutrons you can just subtract and find the difference of the atomic number and mass number. For this lesson and discussion I think my favorite part would be the computing for the atomic mass, atomic number, for the protons, electrons and neutrons. Because it kind of improve my skills in math, as far as you know computation is one of my weakness because I am not that good at it but this lesson wasn’t that complicated and when I was answering the given worksheet it was very fun and it helped me gain knowledge even more about this certain topic. If I would rate my interest and understanding about this lesson I would rate it 5/5, yeah perfect! Because it was discussed really well and it was easy to comprehend. In addition, this type of lesson is what I am looking for so I was very interested in this one. I am looking forward to the upcoming lesson, but so far this one the probably the best and one of my favorite.

# data[].attributes.body
For week 5 we discussed about the History and models of the atom. First, we talked about Democritus and his contribution or theory where in this is where it all started, he believed that matters or universe are made out of invisible units called Atomos.  The next one is John Dalton, he started the Atomic Theory wherein he stated that all elements are composed of tiny indivisible particles called atom, he also believed that atoms of any one element are different from any other element. John Dalton also proposed a theory which is called, Billiard Model wherein this proposed that matter was composed of small, spherical particles. The next one is John Thomson, he proposed an atomic model called Plum Pudding, this came up with the idea of having charges embedded with Dalton’s Billiard Ball. He also used cathode ray experiment that leads to the discovery of the existence of the electrons. Robert Millikan determine the mass of the electron around the year 1916. The next one is the Nuclear Model which is proposed by Ernest Rutherford, he discovered the Nucleus and the Positively Charged subatomic particle called proton. He is also known because of his famous Gold Foil experiment. Then Neils Bohr, he discovered that electrons exist in several distinct layers or levels, he also proposed his atomic model called “Jimmy Neutron Model” wherein the electrons travel around the nucleus just like the planets that revolves around the sun, the electron orbit and electrons can jump between levels with energy being added or released. Lastly Heisenberg and Schrodinger, they found out that electrons live in fuzzy regions or clouds not in distinct orbits, they improved Neils Bohr’s findings about atoms, they also discovered that electrons locations cannot be determined or predicted, lastly they proposed the Quantum Mechanical Model wherein electrons are found in the shells. My favorite part about our discussion is I think the whole lesson because it is the history of atoms which is very entertaining to learn and it captured my interest easily. If I would rate my understanding and interest about this topic, I would give it about 4/5 because the lesson is just a little bit complicated because there are many people that are in this lesson and it is kind of hard to remember each one and their corresponding contributions on the atomic discovery, but I really love this kind of lessons and it is in my field of interest so I give it a thumbs up. I am looking forward to the upcoming lessons for the next week.

# data[].attributes.body
For this week  I have learned about the different Evidences of Chemical Reactions. We actually explained 5 of it and the first one is the Evolution of Light and Heat where in this mostly occur or happens when you light a match stick where combustion happens, the next one is Temperature change to the surroundings a great example of these are hot and ice packs. The third one is Formation of Gasses that are bubbling or having odor other than boiling, I think this one is very helpful because as what our teacher said people who cannot determine whether a food is expired already by tasting it or smelling especially drinks such as spoiled milk, you can hear some bubbling in it. Then the Color change which is due to the formation of new substance, for example rusting of a metal. Lastly, Formation of a precipitate which forms a reaction between two mixed aqueous solutions. My favorite part of our lesson and discussion is when we discussed about the formation of gases because I am one of those person who cannot determine which of the food is already expired, the tip that our teacher gave us is pretty helpful because I can use it in my everyday life and this also lessen the chance of food poisoning. If I would rate my interest and understanding about this lesson I would probably give it 4.5/5 because this lesson is easy to comprehend and the teacher discussed it very well, I didn’t give it fully 5/5 due to the fact that it is a little bit out of my interest. But so far it was pretty good and I am looking forward to the new upcoming lessons.

This week, I am glad that I attended both the synchronous classes we have in Science. The topic that Ma'am EJ discussed is a continuation of our last topic which is Periodic Trends. We focused on Electronegativity and Electron affinity for the first synchronous session. They both increase from left to right, bottom to top. Whereas in the second session, we focused mainly on Ionization energy and Metallic Property of an element. Ionization energy increases from left to right, bottom to top. The Metallic Property does the opposite. It increases from right to left, top to bottom. I did enjoy the discussion, though a bit nervous while reciting. I like organizing the elements by trend the most for this week. But I think I will rate myself 4.5/5 since I'm still not that confident with the trends.

# data[].attributes.body
For this week, I was absent but I read our module and studied it. I studied and learned the history and development of the periodic table. Different scientists were introduced with their discoveries. After studying the history of the periodic table, I studied the trends in the periodic table. I find the written work easy and I understand it very well. Because I was absent, I asked my friend what they discussed and I studied it. I learned about atomic radius and ionization energy. I rate myself 2 out of 5 because I was absent and because of that, I don't have recitation points for that day.

On our 8th week, we had 2 synchronous classes for science since there are a lot to discuss about. We discussed about the trends in the periodic table. Electron affinity and Elctronegativity increases from left to right and bottom to top. For the 2nd synchronous class, we tackled about Ionization energy, it increases from right to left and top to bottom. However, metallic property increases form left to right and bottom to top like the electronegativity and electron affinity. For this session, I will rate myself a 3/5 since I had a poor internet connection and it tends to lag a lot.

# data[].attributes.body
For our 7th week, we discussed the history of the periodic table of elements. We learned about a few chemists or scientist that have proposed the various concepts of the periodic table. Dmitri Mendeleev is the one who proposed the periodic table of elements in 1869. He is also one of the proponents of it. He got credited for it since he made the periodic table with more accuracy than the other chemists and scientists that also did the same. He even left spaces for several undiscovered elements to use in the future. We also tackled about the some trends in the periodic table, which kind of confused me a little. I will also rate myself a 4/5 for this session.

# data[].attributes.body
For our 6th week class, we discussed about atoms. It is called "The Building Block of Matter". It is the smallest possible unit that a matter can be divided, while not changing its properties. It is made up of protons, neutrons, and electrons. Protons are charged particles, Neutrons are neutral or no electric charge, and Electrons are charged particles. They are grouped together and form the nucleus or the center of the atom. We also discussed about atomic number, mass number, and atomic mass. The forces in the atom are gravitational, electromagnetic, strong, and weak force. Isotopes are atoms that have the same number of protons but different numbers of neutrons. Ions are charged particles from electrons and it has 2 types. The anion are the negatives and the cation are the positives. For this session, I will rate myself a 4/5.

Week 8 Reflection - TRENDS IN THE PERIODIC TABLE (May 12,2021)

# data[].attributes.body
I practiced and reviewed for this session so that I won't be that much confused with the periodic trends anymore and so I'll be able to raise my hand and answer in the recitation. We had two classes for this lesson so that we'll have the time to discuss all of it. With all the examples and the recitation, I was able to understand it and not get confused at it anymore, my only problem is I am sort of slow at finding the given elements in the periodic table to answer but I still can manage. My favorite part of the discussion is when we're given the chance to arrange elements in increasing order, because I enjoyed it so much and at the same time, we're also being trained to master the topic. I mastered pretty much all of them. The Trends of the periodic table are Atomic Radius, Electron Affinity, Electronegativity, Ionization Energy, and Metallic Character. The Ionization Energy measures how tightly electrons are bound in an atom. Metallic Property is the ability of atoms to lose electrons. Electron Affinity is the tendency of an atom to accept an electron. Electronegativity is the ability of atom to attract electrons in bond.

I will rate myself 5/5 for this week / session, I was so interested with the lesson and I want to get used to it more.

Science Reflection 3rdQ Week 8 5/14/2021

# data[].attributes.body
In this week, we had two synchronous classes in science. In those two synchronous classes, the first one happened at 5/12/2021 (Tuesday) and there,we started discussing the trends in the periodic table. There, it was discussed that the electron affinity and electronegativity in the periodic table increases from left to right and bottom to top. In the second synchronous class that happened at 5/13/2021 (Wednesday), we had to do it at 2:30pm because ma'am EJ doesn't have synchronous class with us every Wednesdays. In this synchronous class, we continued to learn about trends in the periodic table but this time it is about ionization energy and metallic property. The ionization energy increases in the periodic table from right to left and top to bottom while it is the opposite for metallic property. It increases from left to right and bottom to top just like electron affinity anf electronegativity but in the electronegativity, the noble gases do not have any electronegativity value because they tend not to form bonds. Ma'am EJ also taught us how to know what element has more in one of the trends in the periodic table and I personally liked this because it trained me to identify which is more or less. I also had fun in this lesson because I learned many things specially I had the chance to recite many times. For these synchronous classes, I rate my self 5/5 because I mastered this topic pretty well and I also rate Ma'am EJ and this topic 5/5 because Ma'am EJ was the reason I was able to master these lessons.

For this week, we talked about subatomic particles. We were first introduced to the definition of matter and atom. We then discussed the three subatomic particles which are the neutron, proton, and electron. Protons and neutrons are group together to form the "center" or the nucleus. We also discussed the weight and size comparison of the subatomic particles including the mass and the atomic number. I learned the different forces in an atom. Those forces are the gravitational, electromagnetic, strong, and weak forces. Lastly, we studied how we can get the value of neutrons, atomic mass, and atomic number. For this week, I rate myself 4/5 because I understand our lesson but I know that I can still do better next time especially when it comes to our recitation.

We learned how to draw the following subatomic particles and atoms and labeling them. I also remember doing math at this week by calculating the atoms neutrons, electrons, protons. Ma’am ej also gave us a table to be completed with the elements on the periodic table. I love discussing about the periodic table and it’s elements so i really enjoyed this discussion

This week, Ma’am discussed the Atoms and its subatomic particles. A typical atom consists of three subatomic particles: protons, neutrons, and electrons. I’ve also learned how and where each ones is placed and their function and why they are there. To know how to draw atoms and their subatomic particles.

This week, we learned about the history model of atoms. Atomic models are important because, they help us visualize the interior of atoms and molecules, and thereby predicting properties of matter. I’ve discovered new scientists and their proposal and i’m looking forward to knowing about these scientists in the future.

In this week Ma’am Ej discussed about evidence for a chemical reaction. A chemical change is a change of materials into another, new materials with different properties and one or more than one new substances are formed. It results when a substance combines with another to form a new substance (synthesis or either decomposes to form more substances). The following can indicate that a chemical change has taken place, although this evidence is not conclusive. it also happens when one chemical substance is transformed into one or more different substances, such as when iron becomes rust. A chemical change is different from a physical change, which doesn't rearrange atoms or molecules and produce a completely new substance.

We discussed about subatomic particles and I listened attentively to the lesson and waited for the right time I can raise my hand and recite.  I actually enjoy a lot of those stuff where we just observe and answer the questions and probably guess what will happen to it too. I learned about how adding protons, neutrons and electrons works, and how to make a substance unstable and stable by adding protons or neutrons to it. And how it can change elements too when added something.  My favorite part of the lesson is when computing atomic mass and numbers. At first, I thought it would be hard but when I learned it, it's actually pretty easy to understand. The topic I think I mastered in this session is the same thing too, computing the atomic mass and numbers. I remember the A X Z. In which the A stands for the mass number and the formula is A = Z + N (neutron number). The X stands for the chemical symbol of the element. The Z is the atomic number or the number of protons. At that part we also distinguished the atomic number and the atomic weight in an element. I remember when getting the electrons and protons of an element, it's the same as the mass number. And to get the mass number, you just have to round off the atomic mass. To get the neutron amount, you just have to minus mass number to atomic number and you'll get the answer. I don't pretty much remember every single symbol of an element but I remember most of them and I will try to memorize it again with the use of periodic table

In this session/week, I'd rate myself 5 because I really enjoyed this lesson and understood it well.

Week 7 is kind of tough for me. Mainly because I didn't got a chance to attend our session this week because I have a bad cold. Fortunately, we have our module in the Canvas, so I made sure to read it thoroughly in order to catch up. The topic is again very interesting, so I was sad that I didn't get to attend. The lesson is all about the history of the Periodic Table and the Periodic Trends. At first, I really can't wrap the periodic trends around my head. But as I practice with the activities Ma'am EJ provided in the module, I improved a lot. If I will choose my favorite part in this week, I will probably pick the history of the Periodic Table. It's just always fun for me to be able to know how things are made. All in all, I'll rate myself 4.5/5 as I still am being confused organizing the elements based on the given trends.

# data[].attributes.body
In this week, I've learned a lot about the substance according to its atomic structure. Before we start our discussion, we did the simulation on how the atoms change its net charge, if it's neutral charge or ion, how does an atom change from one element to another, it is because of the protons, electrons and neutrons we applied. In our lesson, my favorite part was about calculating mass number and knowing such subatomic particles. They are atomic number, mass number, atomic mass, electrons, protons, and neutrons. For the reason that I do enjoy calculating even though some parts where I find a bit of hard, it was fun and exciting since when we recite and answer it correctly, we participate in our synchronous classes. Also, we tackle about The forces in the atom such as  Gravitational Force, Electromagnetic Force, Strong Force and Weak Force. I rate myself 4/5 for the reason that I think it was a bit hard for me because of a lot of terms being taught in this week. But in overall I do love the lesson that we've had.

# data[].attributes.body
In this week, our topic is all about the atoms and the sub atomic particles. We even learned about the difference between molecules and atoms. We also learned that the atoms is the smallest possible unit. The atoms is made up of the subatomic particle which is the electron, neutron and proton. We all know that the neutron is a normal charged the proton is positive charged and lastly the electron is the negatively charged. We also learned about the mass of the sub atomic particle. It takes 1839 electrons to equal 1 neutron and 1 proton is equals to 1836.
We learned so much in this week.
The rating is 5/5

Week 7 Reflection - PERIODIC TABLE (May 4,2021)

# data[].attributes.body
Today, we mastered determining and arranging elements by their ionization energy and atomic size. We learned to arranged them in increasing order and the patterns of how they increase or decrease. My favorite part of the session is when we learned the periodic trends because at first, I thought it will be hard but I listened attentively and understood it. I even managed to answer in a recitation by arranging three elements in their increasing order. It was fun learning about it. We we're also taught about the elements in the groups 1A-7A. The areas of the periodic table are nonmetals that are gasses and the three classes of elements of are (metals, nonmetals and metalloids). And of course the Periodic Law that says, when elements are arranged in order of increasing atomic number, there is a periodic repetition of their physical and chemical properties. And also the periodic table history, about what happened in 1869 Dmitri Mendeleev, and about Glenn Seaborg who discovered 8 new elements. The topic I mastered the most are the group of elements (family names) Group 1A are the alkali metals, Group 2A alkaline earth metals, Group 7A halogens.

I think I would rate myself 4/5 this session because I was deeply interested with the topic and it was easy to understand!

# data[].attributes.body
This week is pretty interesting because I get to learned more about the periodic table not just elements that is organized but also the history on how the periodic table is being made from many years, my favorite part is where we arranged the lowest to highest Atomic Radius or Ionization energy it is fun doing it, I would say I mastered it all because the further i understand the topic I easily know how to answer the problems so I would give myself a 5 out of 5

# data[].attributes.body
this week is very good because we get to learn about the Atomic mass,Atomic Number, The three subatomic particles and many more, But my favorite part is solving the atomic mass, the protons/electrons/atomic number of an atom, because it is interesting to solve it and very easy to do it, and pretty sure I mastered it well, So I will give myself a 4 out of 5.

# data[].attributes.body
For this week, we studied the history and model of the atom throughout the years.
Before we started the discussion, we went to the website called quizziz first and answer some questions regarding our topic. We started with Democritus BUT Aristotle said that he was wrong. I learned that John Dalton wrote the first atomic theory, but some of his statements on his theory are wrong. He is wrong with the statement that elements of the same type are identical because they can have a different number of neutrons. Atoms that have the same element but different mass are called isotopes, it was proposed by a scientist named Frederick Soddy, he was the one who corrected the wrong statement of Dalton. We discussed many scientists who proposed their theory regarding the atom. Those scientists include Bohr, Rutherford, J.J Thomson, etc. I understand the lesson that is why I rate myself 4 out of 5 (because I easily forget things and I need to read them repeatedly to avoid forgetting them).

# data[].attributes.body
This week is really interesting and fun for me. I thought it is complicated, but with Ma'am EJ showing us a simulation, it's actually really easy. The topic is all about subatomic particles: proton, electron, and neutron. The relationship between those three are just amazing. On top of all that, I also really enjoyed answering our module. I honestly thought I wouldn't as it include math, but I find it pretty nice finding out those missing in the table. The activity using the simulation one is the best part though. I think I played with it for at least 30 minutes. So with that, I will rate myself 5/5.

This week, we learned all about the periodic table of elements. From the history of the periodic table up to the trends. My favorite part of this week's lesson was learning the trends because it was actually simpler than I thought. Although it requires a bit of hunting and quick eye sight, once you get the hang of it, the task becomes surprisingly easy. For this session, we learned how ionization energy increases from left to right and bottom to top. On the other hand, atomic radius increases from right to left and top to bottom. As of writing this reflection, I haven't answered the module yet, but I'm confident that I'll be able to breeze through it. For this week, I rate myself a 5/5 because I understood and enjoyed the lesson.

In this week, the synchronous session happened on Tuesday due to technical problems that occurred. In this lesson, we tackled three topics which are the history of the periodic table, the parts of the periodic table, and periodic trends. In the history of the periodic table and the parts of the periodic table, it was more of a review since these topic was already discussed when we were grade 7. For the history of the periodic table, these are the things that we learned. Around 350B.C., aristotle said that there were 4 elements which are fire, water, earth, and wind and he believed that these elements combine to form new elements. After that, in 1789, Antoine Lavoisier wrote the first extensive list of 33 elements. In 1829, Johann Dobereiner noticed that some elements e.g. Br, Cl, and I, have similar properties and that Br's mass was between to the mass of Cl and I. This were called triads and there are more triads that Dobereiner noticed. And then in 1864, John Newlands arranged the known 62 elements at the time and he arranged it from lightest to heaviest. He also created the Newland's Law of Octaves. Then at 1869, Dmitri Mendeleev organized it by atomic mass into a table form and the same elements were put into the same column. He was consideed as the Father Of Th Modern Periodic Table. He also left a blanks for the undiscovered elements. Because of this, Periodic Law was born. At 1913, Henry Mosely arranged the elements by atomic number and this created the New Periodic Law. Then lastly, Glenn Seaborg, the person who discovered the 8 elements and the only living person for whom an element is named after. For the arrangement of the table, we learned some terms and how to find an element using these terms. We learned that Periods/Series are the horizontal rows and the Group/Family are the vertical columns. There are 18 series/periods and 9 family/group. We also learned that the periodic law says that when elements are arranged in increasing atomic number, there is a periodic repetition of their physical and chemical properties. In this law also, there are only 7 periods and the group have similar and chemical property and identified by number and letter like IA, IIA. There are also three classes of elements in the periodic table which are the metals, metalloids, and the non-metals. Metals are conductors, have luster, ductile, and malleable, the non-metals are the opposite of the metals, and the metalloids who is in-between the properties of metals and non-metals. You can also see the noble gasses in the periodic table. For the periodic trends, we learned that the atomic radius measures the distance from nucleus to nucleus and divide by two. Atomic radius changes if the element has more or less electrons. If more protons, lesser atomic radius. We also learned about the ionization energy - it is the amount of energy needed to remove an electron from gaseous atom. The ion becomes positive if the electron is removed and vice versa. In viewing the atomic radius in the periodic table, it becomes bigger from right to left and up to down and the Ionization energy is viewed in the periodic table as the opposite of the atomic radius. I rate my self in this lesson as 5/5 since I think I mastered this lesson and my ratings to ma'am ej and for the lesson is 5/5 also because I learned so much.

In the seventh week, we have tackled the development or history of the periodic table of elements. We got to know several chemists who proposed different concepts related to the arrangement of the elements. One of the chemists introduced to us is Dmitri Mendeleev. He proposed the periodic law in 1869 and also one of the proponents of the periodic table. However, he was the one who received more credit because his periodic table was more accurate and he left gaps for the undiscovered elements.

Moreover, we also had the chance to be more familiar with the groups and periods in the periodic table. Furthermore, some trends in the periodic table were introduced to us. I think that my favorite part of the lesson was all about the periodic trends. It is because I find it interesting even though it was confusing at first. These periodic trends serve as the pattern for illustrating the chemical properties of the elements.

In summary, we learned about the history of the periodic table and some of the periodic trends. I would rate myself 5/5 for this week because I think that I mastered the concepts taught to us and also because I somehow did my best to participate.

This week we talked about the Subatomic particles. But before that, what is a matter? As we all know, matter is anything that occupies space and has mass. And Atoms are the smallest possible unit in which matter can be divided. It is made up of subatomic particles such as protons, neutrons, and electrons. Protons are the positively charged particles that is found in the nucleus, the center of an atom. Neutrons are neutral particles that has no charge and it helps to make up the nucleus with proton. Electrons are the negatively charged particle and found outside the nucleus and it orbits the nucleus. It is also equal to the number of protons. Neutrons are more massive than proton by only 3 electrons.
I also learned about the terms atomic number and mass number. Atomic number is simply defined as the number of protons in an atom and mass number is the sum of neutrons and protons in an atom. It is expressed in atomic mass units or amu. There are 4 types of forces that occur in an atom such as strong force, weak force, electromagnetic force, and gravitational force. Strong force is the force that holds the nucleus together. It also counteracts the electromagnetic force. Weak force is responsible for radioactive decay that happens when the nucleus of unstable radioactive atom releases radiation. Electromagnetic force is a force that results from repulsion of like charges and attraction of unlike particles. Lastly, the Gravitational force is the attraction of objects due to its masses. I also learned about atomic mass and how to get it. Atomic mass is the weighted average of an element. I also learned about Ion. It is the charge particle that results from gaining or losing the electrons.

Overall, I rate myself 5/5 because I learned a lot from the lesson and I enjoyed our mini game before discussing it. Thank you Ma’am! <3

This week we talked about the history of an atom and its models. Before we started the discussion, we had a mini game about our topic and it refreshed my mind. Matter is composed of indivisible building blocks. This idea was from Democritus on 400 BC. He called these small building blocks “atomos” meaning indivisible and this is where the “atom” is derived. Aristotle didn’t believe his idea and it took 2000 years to be proved right. John Dalton wrote the first atomic theory and in this atomic theory, he believed that the atoms of the same element are identical, all elements are composed of atoms, and in chemical reactions the atoms are rearranged. But Dalton was wrong about his idea of elements of the same type being identical. Frederic Soddy proposed his idea of isotopes. Isotopes are atoms of the same element having different mass due to the difference of number of neutrons. Dalton proposed the Billiard Ball Model where he believed that matter was composed of small spherical particles. J.J. Thomson proposed the Plum Pudding Model wherein the positive part is the dough and the negative part is the chocolate chip. He also used the cathode ray experiment which led to the discovery of electron. And Ernest Rutherford discovered the Nucleus and the positive protons through his gold foil experiment. It was observed that most of the shots passed through and some bounced back. It led to a conclusion that atoms were made up of small dense nucleus. Niels Bohr discovered that electrons exist in different level and he proposed the Jimmy Neutron Model. Schrodinger improved Bohr’s findings.
I learned that atomic model represents what the structure of an atom could look like and without these, we will not have enough knowledge about the atom. Overall, I rate myself 4/5 based on my understanding about the topic. Thank you Ma’am!

This week, our synchronous classes were moved to Tuesday. Even though I want to attend, I unfortunately didn't get a chance to do so. I was feeling dizzy that day, so I just caught up with the lesson with the ppt and module uploaded by ma'am EJ. The topic is very interesting, so I felt bad that I didn't attend the discussion. It is the history of atom. I am glad that Ma'am EJ gave us an activity, as with that, my knowledge with it deepened more. I especially like the timeline one. Lastly, because I really enjoyed this week, I will rate myself 4.5/5.

This week we discussed more about the atom it's parts and many more. We talked about the forces in the atom (gravitational, electromagnetic, strong and weak), the atomic number, mass number, and atomic mass. My favorite part of the lesson is when we learned on how the different particles affect an atom. I'd rate myself a  5/5 for this lesson.

Our lesson this week is about the history and model of the atom. We talked about how the the atom model was developed and the scientists who helped with the many theories it contains. My favorite part of the lesson was Thomson's "Plum Pudding" or "Chocolate Chip Cookie" Model, wherein the dough part has positive particles whil the chocolate chips are the negative particles. I would rate myself a 5/5, I really enjoyed this lesson ♡´･ᴗ･`♡.

In week 6, we discussed about atom and its subatomic particles. Before we started to discuss we first played with a simulation which you can determine a chemical symbol with just the number of its proton, neutron and electron. After that, we discussed how to get the mass number, atomic number, atomic mass, the proton, neutron and electron of a chemical symbol or an atom. For me, I would rate myself a 5/5 because I was having so much fun finding the mass number, atomic number, the subatomic particles and I fully understand week 6's lesson.

In week 5, our synchronous class has been moved to Tuesday. In our synchronous class we started with a game, which we participated I'm a bit sad because I think I ranked 21st (I'm not sure If it's 20th or 21st). After that, we discussed about the history of atom which Democritus is the one who discovered the invisible particle in the world which he called atomos which after some time more scientists have discovered more about atom. In week 5, I would rate myself 4/5 because I still haven't fully understand the model of atoms.

# data[].attributes.body
In week 4, we started discussing with physical and chemical change. Physical change is when a property of an atom has changed while in chemical change is when a new substance is created. In week 4, I think I would rate myself a 3/5 because there are still some few details that I can't understand.

# data[].attributes.body
For this week, I learned about the difference between atoms and molecules, The subatomic particles of an atom, the definition of atom, nucleus, protons, neutrons and electrons and the weight of the subatomic particles. Alongside those, there are also the atomic number, forces in the atom, isotopes, ion, atomic mass and mass number. I really liked the lesson because it involves math which im pretty comfortable at and I genuinely liked the lesson. I rate myself 5 out of 5 because the lesson was light and fun.

# data[].attributes.body
Week 5, we tackled about history of theories and experiments regarding atoms.400 BC, Democritus believed that the universe is made up of invisible units and he called them atoms. Following his steps, John Dalton wrote the first atomic theory in the early 1800s. in 1804, John Dalton also proposed about the “Billiard ball” model which states that matter was composed of small, spherical particles. During the 1900s, atoms are discovered to have a positive and negative parts. In 1912, Frederick Soddy proposed the idea of isotopes. Lots of models of atoms was made later on, this includes the “chocolate chip cookie” model of J.J. Thomson, The nuclear model by Ernest Rutherford and the “Jimmy Neutron model” of Niels Bohr. The current and most accurate model is the Quantum Mechanical model, which contains complex concepts and mathematics. Overall I rate myself 5 out of 5 because I rarely enjoy history but this lesson made me want to learn more.

Contrast to last week’s lesson, This week we learned more about chemical reaction. Chemical changes, creates new substances by rearranging the atoms of the matter. We also discussed about the law of conservation of mass, the law states that during chemical reaction, the mass is neither created nor destroyed. The highlighted topic in this week was the evidences for a chemical reaction. The evidences are The evolution of light or heat, Temperature change, formation of gas, color change and formation of a precipitate from the reaction of two aqueous solutions. I rate myself 4 out of 5, The lesson was hard but also easy at the same time.
