Which of these students is doing a demonstration that proves matter is made of tiny particles we cannot see?

• Monica blows air into a balloon and it gets bigger and bigger. She can't see anything inside the balloon, but she can feel that there is air in it!
• Deontay is ripping apart a piece of paper. He keeps ripping it into smaller pieces until he can't anymore. He thinks if he had a machine to keep ripping it, he could make it smaller.
• Celeste is using a light to grow plants in a dark closet indoors. The plants are growing even though they aren't in the sun!

What type of matter is described below?

• In this type of matter, the particles have very little attraction to each other. They are far apart and frozen in place, but can slide past each other if necessary.

True or False: In a liquid, the particles are attracted to each other but not as much as they are in a solid. The particles of a liquid are close together, always moving, and can slide past one another.
