I'm officially 22 this year. I was born and raised in Penang, Malaysia. Currently, I'm studying Bachelor of Education (Primary Education) seventh semester of my second year in Taylor's Lakeside University. Since ever small, I'm really passionate in teaching and wants to accomplish certain goals in my life as an educator.]]> 2018-08-29 13:54:17 UTC https://padlet.com/kavethashan18/h8ls617jd40i/wish/276219738 *Framework* kavethashan18 https://padlet.com/kavethashan18/h8ls617jd40i/wish/276223688 1. Things I learned in today's lesson
I learned about inquiry-based learning methods, the role of facilitator, the theories that are suitable to teach Science to the students and science framework of Singapore syllabus.

2. Things that are new to me.
The things that are new to me are about the aims of Singapore Primary Science Curriculum and certain science topics that taught in primary levels which are from grade 3 onwards.

3. Things I found interesting.
 I found that there is a framework pattern between the science topics that taught at the lower primary levels (grade 3 & 4) and science topics that taught at the higher primary levels (grade 5 & 6).

4. How will this knowledge help me as a science teacher?
Knowing about the curriculum and framework will help me to comprehend the information and could apply that knowledge in my future science classes. I will also prepare myself with lesson plans and on how am I going to deliver the lesson to the students effectively. In addition, I will consider the activities that will be assigned to the students where they have to solve the problems scientifically and able to produce a proper justification for it.

I learned how to conduct a survey/questionnaire with proper procedures and methods. I also learned how to compile the data that we collected according to themes and responses. 

2. Things that are new to me.
The things that are new to me is breaking down the qualitative data into smaller chunks and making a conclusion based on the data that we derived during our survey.

3. Things I found interesting.
I found interesting by interacting with other students around my campus randomly and asking them for help to fill in the questionnaire that we prepared for the survey.

4. How will this knowledge help me as a science teacher?
Based on my understanding from the conclusion that I received from the survey was most of the students have different perspectives regarding energy and its importance. As a science teacher in future, I will take into consideration how to deliver the contents in more efficient and interactive ways by making connections to real life situation. 

For example, teach students why is it important to conserve energy? The reason why it is important to conserve energy because it is good for the environment as we use less energy, we are able to save natural resources and cut down on pollution. 

In addition, the methods that I learned on how to conduct a questionnaire will also help in my future science classes as I can conduct a survey with my students in order to check their understanding level of the topic that I taught to them.]]> 2018-08-31 10:47:38 UTC https://padlet.com/kavethashan18/h8ls617jd40i/wish/276848965 *Different forms of Energy* kavethashan18 https://padlet.com/kavethashan18/h8ls617jd40i/wish/280819969 1. Things I learned in today's lesson
I learned what are the different forms of energy such as potential and kinetic energy and why is it important to conserve energy.

2. Things that are new to me.
The things that are new to me is how an energy transform into another form of energy. Even though I learnt this knowledge before, when I studied and did my readings on the conservation of energy, it’s really a deep knowledge. The total amount of energy at the end is the same as in the beginning energy. For example, turning old phones into medals is a form of a chemical energy.


3. Things I found interesting.
I found interesting is that the magnetic field is not static, it moves. Magnetic energy is always moving in and out of the poles and it creates motion. Therefore, magnetic energy is under kinetic energy. Electrons move in order to produce electricity.

4. How will this knowledge help me as a science teacher?
As a science teacher, I will model some of the energy experiments such as coiling snake experiment and also motivate the students to experience the activity by them own. The reason why is hands-on activities help students to develop their knowledge and understanding of scientific ideas.

]]> 2018-09-13 13:34:58 UTC https://padlet.com/kavethashan18/h8ls617jd40i/wish/280819969 *Misconceptions on the different forms of Energy* kavethashan18 https://padlet.com/kavethashan18/h8ls617jd40i/wish/283469480 1. Things I learned in today's lesson
For today's lesson, I learned some important information on different forms of energy and the underlying problems which may lead to several misconceptions.

a) Thanks to Ms Nor for the recap of our previous lesson: Different forms of energy. The revision was very helpful for me since I was away from my practical last week. I understand that there are two forms of Energy which are
- Kinetic Energy: energy that it possesses due to its motion. {light, sound, thermal, mechanical and magnetic}
- Potential Energy: energy is stored in an object. {Gravitational, Elastic, Nuclear and Chemical}

b) Misconceptions: Some learners will tend to generate their knowledge based on incomplete pieces of evidence which may lead to a confusion of science contents.

2. Things that are new to me.
The things that are new to me are:
a) "How do we see colours?". Before this, I never knew how to explain this question but now I have some understanding regarding it. So, when the light receptors travel to our eyes with the help of photoreceptor cells, it will transmit messages to our brain, which produces the familiar sensations of a respective colour. The surface of an object reflects only some colours and absorbs all the others. We perceive only the reflected colours. For example, if the chair is an orange colour, it means that the chair absorbs other colours except for orange colour.

b) Another thing that is new to me is "how do we see an image?" The image that we see in reality is totally different from the image formed in our retina. So, when I searched on the Internet, the explanation was given as this; Because the front part of the eye is curved, it bends the light, creating an upside down image on the retina. The brain eventually turns the image the right way up."

3. Things I found interesting.
I found interesting about an information about heat. The video that I saw on the misconception of heat, they carried out an experiment between the cake and the cake tray. Thus, we need to find out the temperature of both. Initially, I thought the tray will be hotter or have a higher temperature than the cake. However, it shows that both have the same temperature because it was exposed to the same surroundings. This is was really an eye-opener for me because even I had the misconception earlier but now I'm able to correct it. 

4. How will this knowledge help me as a science teacher?
As a science teacher, I would take my student's misconceptions into account and will find some possible ways to address those problems. Then, I will explain why it occurs and why we have to change our thoughts to my learners so that they will be able to eliminate their past experience and absorb new information. According to Ms Nor's advice of carrying our experiment will help students to understand better because students are able to visualize what they are learning and able to make a conclusion from it. For example, balloon powered car or the fruit battery. I also will carry out some activities that can be relevant to the topic so it will be a handful for the student's learning. ]]> 2018-09-19 14:59:15 UTC https://padlet.com/kavethashan18/h8ls617jd40i/wish/283469480 *The transformation of Energy* kavethashan18 https://padlet.com/kavethashan18/h8ls617jd40i/wish/285814173 1.Things I learned in today's lesson.
I learned about some misconceptions regarding energy such as when an object at a rest; does it contains energy or not and energy is all used up. I also get to know some strategies and ideas to address those misconceptions from my classmates. Then, I learned about an energy transformation vs an energy transference. I really paid attention to this topic because I'm doing Energy Transformation topic for my e-book. Therefore, I get to learn some important information that I need to take into consideration.

2. Things that are new to me.
The things that are new to me is about the energy transference. Initially, I don't have a clear understanding of what is transference. After Ms Nor's explanation, I get to understand that energy transfer is the movement of energy from one location to another. For example, transferring electricity from a wall plug through a charger to a  computer. However, in the primary syllabus, we wouldn't be teaching energy transference to the students so Ms Nor asked to focus on transformation. Although, it was good to learn a new knowledge.

3. Things I found interesting.
I found two things interesting in today's lesson. First of all, the Kahoot quiz. Even though I played that quiz several times, it still the best to reflect our understanding when doing the quiz and also keep us engaged throughout the activity. Secondly, the video that was displayed by Cheryl and Lynn's group about Energy. It was truly simple and amazing. The video explains clearly about the potential and kinetic energy. Surely, I will use this kind of video in my future teaching because it will show a clear picture of what they learn.

4. How will this knowledge help me as a science teacher.
Knowing about the curriculum and framework will help me to take into account students misconception and will implement methods to tackle the problems. 

There are some ways that I learnt from today's lesson which are:
- modelling 
- eliminate their misconception by showing examples
- inquiry-based learning 
- experiments
- examples
- create simple activities based on the curriculum
- display household objects (such as toys, battery) to guess what energy stored and how the energy transform into another form of energy.

I learned the 5E lesson plan and some experimental ideas that my friend has proposed to teach Energy for the students. From today's lesson, I discovered certain misconceptions on the transformation of energy that might the student have.

2. Things that are new to me.
The things that are new to me is how to deliver the content (eg: Transformation of Energy) to students for a better understanding. My past experience of learning science is merely on traditional method where we only use textbooks and notes from the teacher. I have no experience of carrying out activity on my own. Therefore, teaching my students on conducting experiments will be great exposure for students as well as myself.  In addition, I'm really amazed and knowledgeable of some ideas that my classmates thought me. 

3. Things I found interesting.
Today, my group presented about the lemon experiment for our 5E lesson. So, when Ms Nor gave feedback on our presentation, she asked us to do you what are the fruits and vegetables that can generates more electricity. Based on my perspective, I know that the food that usually produces electricity are the ones that are high in acidity so lemon is a good example. However, when I did my research to learn more, I found that even carrots, cucumber and sweet potatoes can also conduct electricity because it contains potassium.

4. How will this knowledge help me as a science teacher.
As a science teacher, I will direct my class to be more comprehensive and also include inquiry learning to arouse student's curiosity to learn more about Science. I will implement more experiment for them to carry out so that they are accessible for the answers. It also help them to conclude their experiment based on what they have observed. ]]> 2018-10-03 00:13:35 UTC https://padlet.com/kavethashan18/h8ls617jd40i/wish/288414223 * Core ideas in Force* kavethashan18 https://padlet.com/kavethashan18/h8ls617jd40i/wish/291332858 1.Things I learned in today's lesson.
In today's lesson, I learned about the exact meaning of force and some misconceptions of force many misconceptions. The meaning of force is a push or pull upon an object resulting from the object's interaction with another object.

2. Things that are new to me.
Based on my prior knowledge, I have only learned about the gravitational force which pulls us to the center of the Earth. However, there is a normal force is support force exerted upon an object that is in contact with another stable object. In scientific term, it defines as a force that is directed perpendicular to the two surfaces in contact. It makes sense that the force is perpendicular to the surface since the normal force is what prevents solid objects from passing through each other.

3. Things I found interesting.
There are 2 things I found interesting in the class. Firstly, I really like the video that Ms Nor played in the class. It was really attractive and understandable as well. Secondly, my group mates and I were assigned to conduct a mini-survey to know about student's view on the force. It was really surprised to see the student's answers. Different people have a different perception of force concept.

4. How will this knowledge help me as a science teacher?
As a science teacher, I think I will
- play videos in class for the students to visualize the concept of force rather than just reading from books
- ask my students to conduct real-life experiments for them to get the clear view of how force is being applied.]]> 2018-10-10 16:09:44 UTC https://padlet.com/kavethashan18/h8ls617jd40i/wish/291332858 * Gravitational Force* kavethashan18 https://padlet.com/kavethashan18/h8ls617jd40i/wish/296235494 1.Things I learned in today's lesson.
In today's lesson, I learned about Newton's 1st, 2nd and 3rd law regarding forces. Based on my understanding, Newton 1st Law is an object which is at rest will remain rest and an object in motion will stay in motion at a constant speed unless an outside force acts on the object. Next, Newton's 2nd Law is the unbalanced force acting on an object equals the object's mass times its acceleration. Lastly, Newton's 3rd law is a law of interactions where for every action there is an equal and opposite reaction.

2. Things that are new to me
I would say that there are 4 terms that were new to me; contact vs non contact force & balance vs unbalanced force.
- Contact force is when it required touching or being in contact to produce an effect.
- Non-contact force is an opposite of contact force, it does not require being in contact to produce the effect.
- Balanced force is  when forces are equal in size and in opposite direction. Net force = 0
- Unbalanced force is when forces not equal in size and in opposite/different/same direction

3. Things I found interesting
In the slides, there is a question asked why doesn't the moon fall to the Earth. So, the answer is the moon is being pulled towards the earth by the earth's gravity. Simultaneously, the moon is ALSO pulling the earth towards the moon’s center at the same
time. If the moon is stationary, it will be crashing down into the earth. Hence, now only I understand that two forces are exerting on the same times when a force is applied to an object. 

4. How will this knowledge help me as a science teacher?
As a science teacher, I will
- show many real life examples to my students on how gravity works such as how astronauts are in the space. 
- help them to clear all their misconception before they absorb new things about force. ]]> 2018-10-24 00:15:58 UTC https://padlet.com/kavethashan18/h8ls617jd40i/wish/296235494 * Misconceptions on the Gravitational Force* kavethashan18 https://padlet.com/kavethashan18/h8ls617jd40i/wish/296235754 1.Things I learned in today's lesson.
In today's lesson, I learned about
the misconception of gravitational force.

2. Things that are new to me
I came to know about how science syllabus has been established. In the Science curriculum, there is a two year gap in the teaching of forces. The reason why is in younger students cannot understand abstract concepts because Students cannot see or touch or play around with force. However, in Year 6,  students are to be
able to define what a force is without seeing it, touching it. They are required to state the
effects of forces such as a force can move a stationary object. Students will need to
imagine and use their logical thinking to understand this concept. Now, I understand that there is a purpose why students learn about force after a two year gap.

3. Things I found interesting
There are 5 different categories in misconceptions.
1st (Preconceived Notion)
- conceptions that rooted in everyday experiences and incomplete observations
2nd (Non-scientific beliefs)
- students learned from sources; religious or mythical teachings other than scientific education
3rd (Conceptual Misunderstanding)
- hen learners are not encouraged to examine differences between their own beliefs and “real sciences”
4th (Vernacular Misconception)
- the choices of words confuse learners; it mean one thing in everyday life and another in a scientific context
5th (Factual Misconception)
- building understanding on false statements.

4. How will this knowledge help me as a science teacher?
I will use the information that I learned in my class in the future. By understanding the different categories of misconception in science, I will be able to identify what misunderstanding that my students faced and will find out some possibilities to omit those doubts. So, that learners will learn the proper scientific facts. 
]]> 2018-10-24 00:17:42 UTC https://padlet.com/kavethashan18/h8ls617jd40i/wish/296235754 * Strong Forces* kavethashan18 https://padlet.com/kavethashan18/h8ls617jd40i/wish/306067906 1.Things I learned in today's lesson.
In today's lesson, I learned about the 4 fundamental forces of nature:
- Strong Force = Strong Nuclear Force & Electromagnetic Force
- Weak Force = Weak Nuclear Force & Gravitational Force.

2. Things that are new to me.
To be honest, I was freak out when I learned about the 4 fundamental nature of force and I couldn't understand in the first study. Therefore, I revised this lesson for several times to get me understand.
# Strong Nuclear force is very strong and attractive but very short-ranged (10^-13)
# Electromagnetic force cause electric and magnetic effects, can be attractive/ repulsive and it acts only between pieces of matter carrying electrical charges. It has long ranged.
# Weak Nuclear force is responsible for radioactive decay & neutrino interactions. It has very short range.
# Gravitational force is the weakest among the four fundamental force. It has a very long ranged. It is always attractive and acts between any two pieces of matter in the Universe.

3. Things I found interesting
The uses of strong nuclear force in everyday life 
  • Table, chair, mobile phones, buildings, etc 
  • Atoms are the building blocks of things 
  • Strong nuclear force keeps the things such as tables and chairs together 
The uses of electromagnetic force in everyday life
  • Composes, headphones, traffic signals, audio speakers, car horn

4. How will this knowledge help me as a science teacher? 
I will use the information that I learned in my class by explaining each force explicitly and provide examples to the students. By explaining in detail, students would be able to grasp the information.

It was a blended learning week and we were assigned to design an activity or an experiment to address the misconception given

2. Things that are new to me.
There are some misconceptions listed was new to me. For example, only magnets produce magnetic fields.

3. Things I found interesting.
Misconceptions of Electromagnetic force
1. All silver colored items are attracted to a magnet.
2. All metals are attracted to a magnet
3. Only magnets produce magnetic fields
4. Larger magnets are stronger than smaller magnets
5. All magnets are made of iron
6. A magnetic field is a pattern of lines (not a field of force) that surrounds a magnet
7. Magnetism does not go through objects

4. How will this knowledge help me as a science teacher?
It will be very helpful to me since I came to know a list of misconceptions that the students might have. Therefore, it would be a handful tool to encounter those misconceptions and will address that before I introduce the topic to my learners. Surely, I will use visual aids such as Youtube or pictures to explain the facts. ]]> 2018-11-20 06:41:55 UTC https://padlet.com/kavethashan18/h8ls617jd40i/wish/306209802 * Weak force* kavethashan18 https://padlet.com/kavethashan18/h8ls617jd40i/wish/306210020 1. Things that I learned in today's lesson.
In today's lesson, I learned about the weak nuclear force and gravitational force.

2. Things that are new to me
The weak nuclear force is responsible for 3 types of decay.
1. Alpha decay - is the emission (discharge) of Helium (He) nucleus from an atom
2. Beta decay - is when an electron.positron is emitted from an atom
3. Gamma decay- is emission of high energy photon from an atom

3. Things I found interesting
I came to know about the nuclear technology which is in Malaysia which is called as MINT ( The Malaysian Institute for Nuclear Technology Research)

4. How will this knowledge help me as a science teacher?
In fact, I also learned the consequences of radiation. Radioactive decay produces isotopes. These isotopes are used in the food industry or agriculture for various
reasons.]]> 2018-11-20 06:44:02 UTC https://padlet.com/kavethashan18/h8ls617jd40i/wish/306210020 * Misconceptions of Weak force* kavethashan18 https://padlet.com/kavethashan18/h8ls617jd40i/wish/306219255 1. Things that I learned in today's lesson.
In today's lesson, we did a recap of 4 fundamental forces in nature and misconceptions on weak force (gravitational force)

Where we can find those elements in our real life
the fusion/fission of weak force happened in the Sun
Strawberry and mango washed in gamma rays
