Kid's learn about the science of states of matter. Solids, liquids, gases, and even plasma.

Watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Relate the...

Matter of any type can be subdivided into particles that are too small to see, but even then the matter still exists and can be detected by other means. Students will participate in hands-on activities to prove that matter is made up of...

What causes frost to form on the outside of a cold container? In this activity, students will see that the liquid water can change state again and freeze to become ice.

A tutorial reviewing the states of matter and the effects of heating and cooling matter in the different states. (Note: some of the links may not load in the archived version of the site.)

Learn how states of matter are dependent on an object's average kinetic energy.
