Lesson Plan - Get It!
Before you take this review, can you find an example of a solid, liquid, and gas in this picture? Don't forget, most gases cannot be seen!
All throughout this series, States of Matter, you have been exploring solids, liquids, and gases.
If you missed any of the previous lessons, you won't have anything to review, so you can catch up with the Related Lessons in the right-hand sidebar.
You looked for these properties of matter in a picture. There are many examples of solids, liquids, and gases in the picture. Did you find any of these examples?
- Solids Boats, trees, houses, grass, and plants
- Liquid River
- Gas Oxygen (Air)
All objects are made up of atoms and molecules. Do you remember what a molecule is? Atoms move around.
- The atoms and molecules in gases move around a lot and are spread far apart.
- Liquids have atoms and molecules that move around, but stay somewhat close together.
- Liquids and gases both take the shape of the container they are placed in.
- Solids have tightly-packed atoms and molecules. Solids keep their shape.
The picture below shows the atoms and molecules in a gas, liquid, and solid:
Here are some examples of each state of matter. Tell your parent or teacher what you see in each picture. Each group of pictures shows matter as either a solid, liquid, or gas:
After looking at the examples, move on to the Got It? section to continue your review of solids, liquids, and gases.
