How does temperature affect matter (Double Points)
As its temperature increases, many kinds of matter change from a solid to a liquid to a gas. As its temperature decreases, that matter changes from a gas to a liquid to a solid. As the temperature increases, the particles begin to move faster and cause them to change states.

True!

Compare the three most common states of matter (Depending on your answer you could earn double points here!)
Solids keep their shape. Particles in a solid are packed tightly together and vibrate back and forth. Liquids take the shape of their container. Particles in a liquid are further apart than those of a solid but closer together than those of a gas. Particles in a liquid move faster than those of a solid but not as fast as those of a liquid. A gas's shape, volume, and size will change depending on the container. Particles in a gas are very spread out and move quickly in all directions.

How can a balloon be used to demonstrate that matter is made of particles too small to be seen.
You can show that a matter is too small to be seen by blowing up the balloon. It shows you that even though you cannot see the matter (air) that we blow out, it does have mass and it takes up space causing the balloon to expand. Also, you can feel the air come out of the balloon even though you cannot see it.
