In this semester we learned about matter, which made up everything that have weight. We also learned about mixtures that have two types, heterougeneous and homogeneous mixtures. We also learned that solutions are a type of homogeneous mixture too. We then learned about physical and chemical changes and the law of conservation of mass. We know that mass is mainly in four states: solid, liquid, gas, and plasma. Ice cube is a solid state but when it melt it is water, a liquid state. A gas state is the air and a plasma state is the gas full of electricity.

Then in book two, we learned the plant structures and how they grow. We learned photosynthesis, which I think is very interesting. The tissues inside the plants, xylem and phloem all have their jobs. And the stomata is on the leaf of the plant. It can close and open which is useful to the plants. We then learned ecosystems with abiotic and biotic factors in it. Sometimes invasive species cause harm to the ecosystems. The predator will also eat prey. The animals interact with each other, and animals interact with plants too.We also learned about the energy flow of the producer, consumer and decomposers, which is shown on food web and food chain. We learned about water cycle, nitrogen cycle, and carbon cycle. We learned about the four spheres too: the atmosphere, geosphere, hydrosphere and biosphere. I think learning all those are useful because I want to be a scientist when growing up and want to use the things I learned to make the world a better place.

In this semester I learned matter, mass, volume, physical changes, chemical changes, plants photosynthesis, food chains, food webs, decomposers, consumers, producers, cycles, and spheres.

Matter is basically solid, liquid, and gas mass is how much it weighs, and volume is how much it takes place.

Physical changes are changes that can be returned into its original position chemical changes are changes that cannot turn back to its original position.

Food chain is simple version of food web, and food web is how animals eat animals/plants. Producers make their own food and produce food for consumers, consumers are mostly animals who eat other animals or eating producers, including carnivores, herbivores, and omnivores. Decomposers are objects that try to decompose things into missing parts. Cycles were oxygen cycle, nutrient cycle, carbon cycle, and water cycle.

Photosynthesis means a plant producing sugar and oxygen which needs CO2, water, and sunlight. The spheres are geosphere, biosphere, hydrosphere, and atmosphere.

In this semester(or quater),We learned many things and we have some fun.We learn mass,matter, phisical or chemical and stuffs like that.And the next few weeks we learned that food chain,web,and things about bios phere and other things.

First, we learn about matter and mass, also physical and chemical property and how they change. Also, how photosynthesis work. I think that is pretty wonderful because of how it works.

We also learn about the food chain and food web, and how it works with decomposers, producer, and many part of it. We learn that four parts of the earth, geosphere, biosphere, hydrosphere, and atmosphere. And I think that is important to us for any sphere to live on earth

In Q1 we learned about physical and chemical properties and changes. In Q2 we learned about biosphere, hydrosphere, geosphere and atmosphere. We also learned about the energy flow between producers, consumers and decomposers. Also, we learned about photosynthesis, which I think is interesting. We learned about the water cycle, the carbon cycle and the nitrogen cycle. I think they will help me when I grow up because I want to be a scientist.

I learned food chain , food web, energy flow, producers, consumer, and decomposer. It is important to learn about that because it can help us to understand how the animals in the ecosystem work. And then we learn about Earth systems it is important to learn about that because in the future I can use the information to help the Earth. I also learned about water cycle it can help me to understand how water in the earth works and how lakes sea rain works.

In this semester we learned about the four spheres atmosphere,biosphere, geosphere, and hydrosphere, we also learned about food webs and food chains, it’s important to learn about it because then later on you can know if they are a carnivore, producer, or decomposer and know better about them.

# data[].attributes.body
What we learned this semester is physical and chemical changes, mixtures and solutions, heterogenous and homogenous mixtures, how does plants survive in the ecosystem, the different relationships in the ecosystem, food web and food chain, and the Earth’s four spheres - biosphere, geosphere, hydrosphere, and atmosphere.
I think that learning the different relationships in the ecosystem is the most important because this way we can understand how does our ecosystem stay balanced. So learning this is important. I think that i learned a lot this semester and I will use these thinkings to help me in my later life.

we learned about fungus like mushroom,and a special kind of ''decomposer.''We also learned about food chain and food web, I think animal in differnt level of consumer is very important because or else there will too many living thing in our plant and all of us can not have energy from eachorther, like all people said , when animals or human dies, there will always be new one born , that is also a cycle of lives.

In this semester, I learned about photosynthesis, which is a way how plants make their own food, unlike humans. And we also learned about the four spheres, biosphere, hydrosphere, atmosphere, and geosphere. Which the layers on earth.
And we also learned about food webs, food chains, producers, decomposers, and consumers. And we also learned about the biotic factors and the process of how energy transfers through food webs. And all of these are important for me because in the future when I see things, I can always remember about the things I learned.

# data[].attributes.body
I learned about many types of things on the earth like ecosystems, the Atmosphere, the Geosphere, Biosphere, and Hydrosphere. Also, about the food chain, and food web. I did well in the learning process like taking more notes and reviewing them before tests. This made my grade come up. We learned about decomposers, producers, and many other new things that I didn't even know about when they had an eating process. This information made me many more opinions and ideas, which made my brain smarter. These are the most important things I think I learned in this school year.

# data[].attributes.body
this semester, I learn all about food chains, food webs, photosynthesis, cycles, molecules, and the four main things that the earth is made up of. ( geosphere, hydrosphere, atmosphere, and biosphere) we also learn all about the biotic factors. i remember how we learn all about the affection of the population according to the different animals. also the living things inside leaves and things all around us. these are only things from the second semester. in the first semester, we learn about the particles around us, liquid gas solid and plasma, energy flow, and chemical or physical change.

I learned matter and mixtures. Matter is anything that has mass and volume. Mixture can be divided into two categories, homogeneous or heterogeneous mixtures.
Also, I learned about chemical changes and physical changes. Chemical changes differ with physical changes by how they produce a new substance.
I learned food chain and food web. I learned producer, primary consumer, secondary consumer, final consumer, and decomposers. I also learned the 4 spheres of the Earth (Geosphere, Biosphere, Atmosphere, and Hydrosphere).

I didn’t really done well at science but I learn matters, mass, volume, physical change, and chemical change. We also learn  food chain, food web, carbon cycles, atmosphere......but most important thing is the energy flow, and how invasive species were bad to the ecosystem. I think I should review more.

# data[].attributes.body
In science we learned about Food chains, Food webs and the spheres and, Geosphere, Biosphere, Atmosphere and Hydrosphere. We also learned about different species and we also learned how Photosynthesis works and we learned of Consumer, Producer, And Decomposer.

# data[].attributes.body
I learned about the food webs,food chains, producer, decomposers, consumers, spheres such as hydrosphere and bioshere, cycles, and many other things.
Producers produce their own food and eat it. Hydrosphere is everything on the planet that has water…. These are some things I learned during semester 2.

Michele: In this semester, we learned about the four spheres of earth(atmosphere, geosphere, biosphere, and hydrosphere) We also learned about the food chain and biotic factors.
Something else we worked on was the population on different species and the effect

I learned about the four things in our earth. Geosphere, Biosphere, Hydrosphere, and atmosphere. I think what I did well in this semester is that I took the time learning about all the things I have to know about and respected the things I am learning. What I could do better is to pay more attention to the teacher at all times in class. —5B Eren M.

In science this semester we learned about the spheres, food chains, food webs and many cycles
I think the spheres are the most intriguing because there are so many layers Earth.

I learned about food webs, food chains, and different cycles and spheres: hydrosphere, geosphere, biosphere, and atmosphere, and biotic factors.
I'm good at food webs and food chains, but I had a little of trouble when I learned the biotic factors. Some vocabulary I learned are producers, consumers, and decomposers
