In science class this year, I've learned a lot of interesting things! We covered three main topics: solids, liquids, and gases, forces, and organisms and cells. Each topic has taught me something new about the world around us.
In Term One, we learned about solids, liquids, and gases. I discovered that these are the three main states of matter, and they are all made up of tiny particles that are too small to see. In solids, the particles are tightly packed together and don't move much, which is why solids keep their shape. Liquids have particles that can move around more freely, which is why liquids can flow and take the shape of whatever container they’re in. Gases have particles that are very spread out and move quickly, so gases can fill any space. This helped me understand how everyday things like water, air, and ice all behave differently depending on their state.
In Term Two, we focused on forces. Forces are what cause objects to move or change speed. I learned that there are different types of forces, like gravity, friction, and magnetism. Gravity is the force that pulls everything toward the Earth, which is why things fall when you drop them. Friction is the force that happens when two surfaces rub together, like when you slide your feet on the ground or when you rub your hands together to warm them up. Magnetism is a force that can attract or repel certain metals.
In Term Three, we started learning about organisms and cells. I found it really interesting that all living things are made up of tiny building blocks called cells. These cells are so small that we can’t see them without a microscope. Every organism, from the smallest insect to the biggest tree, is made up of cells, but different organisms have different types of cells. For example, animals and plants have special cells that help them survive in their environments. I also learned that cells have different parts, like the nucleus, which controls the cell, and the cell membrane, which helps the cell stay protected. We also discussed how groups of cells work together to form tissues, organs, and even whole systems in the body, like the digestive system.
Overall, science this year has helped me better understand how the world works. It’s amazing to think about how everything is made up of tiny particles and how forces and cells are constantly at work all around us. I’m excited to keep learning more!
