2. Matter, Matter Everywhere Can you name some things that are matter? Matter comes in many shapes and sizes, but there are only three types, or states, of matter. Do you know what they are called? LiquidsSolidsGases What is matter? Matter is anything that takes up space and has a mass.

3. Solids What if you were to pick up a solid object, such as a block and move it from place to place around the room? What would you see? Click on the block to find out! Did the block change at all? Did it get bigger? Or flatter? No, it stayed the same no matter where it was!

4. What Makes a Solid a Solid? Of course the block did not change! That is because it is a solid. A will always have the same shape and take up the same amount of space no matter where it is in the room. solid Can you name some other solids in the classroom?

5. Liquids If you take the water from the big glass and pour it into the smaller glass, what will happen to the water? Click on the glass of water and find out! Did the shape of the water change? Did the amount of water change?

6. What Makes a Liquid a Liquid? The shape of the water changed, but the amount stayed the same. That is because water is a liquid. A will take up the same amount of space (like a solid) but it takes the shape of the container it is in. liquid Can you name some other liquids in the classroom?

7. Gases Gases are tough to figure out! Gases can change the amount of space they take up very easily. Because of this, they will also take the shape of the container they are in. Click on the bubbles to see how gas acts in a container.

8. Do Gases Really Exist? Can you see gases? Gases are like little super balls that bounce all around the inside of their container. So how do we know gases exist? Take a deep breath. What do you notice? You chest gets bigger because your lungs fill with air which is a special mix of gases. The air takes the shape of your lungs.

9. Are Gases Really Matter? How do we know that gas is matter? Take a Ziploc baggie and scoop some air into the bag and close the bag tight. Try to squeeze the bag. What happens? Can you put something where the bag is? So gases do take up space and scientists have special equipment to measure the mass of a gas.

10. States of Matter A solid has a definite shape and a definite volume. A liquid has a definite volume but takes the shape of the container it is in. A gas take the shape of the container it is in and will change shape very easily.
