Levels: Grades 2-5
Description: In this fun science activity, students learn about solids, liquids and gases as they experiment with the conditions that change them from one form to another. Water is a common example, as it exists in all three forms--as ice, liquid water and steam. Challenge students to find the correct category for other examples such as milk, sand, rain, helium, wood and air. Watch what happens when you heat liquids and cool gases. Explore the key scientific processes that change solids, liquids and gases from one form to another.
