Changing Water

In science class, you have been learning about the water cycle and how heat and cold play a role in how water changes form. In this activity, you and your family members can observe how temperature changes the form of water.

Materials

• ice cubes
• pan for boiling water
• bowl
• paper and pencil

Procedure

Set out ice cubes in a bowl on the counter. Draw a picture of the ice cubes. Mark the time. Check on the ice cubes every half-hour. How long did it take for the ice to melt? With an adult's help, pour the melted ice cubes (liquid) into the pan and boil the water. Record what you see.

Results

What forms of water did you see in this activity? When was the water in solid form? in liquid form? in gas form? What would have happened if you had put the liquid in the freezer instead of in the pan to boil?
