Assignment: 4.
Experiment: Changing Liquid to a Gas
Follow the directions on the OW project page.
Information: When water boils, the heat energy makes the water molecules move so fast that they push away from each other and escape into the air. They evaporate. They become a gas. Heat energy from the sun or in the air of a heated room can cause water to evaporate. Evaporation takes longer than boiling, but it happens just the same.

Assignment: 7. Experiment: Friction
Follow the directions on the OW project page after reading the paragraph below.
This experiment is about how heat is made by friction. Read through the OW page and complete the experiment being sure to pay attention to the temperature of the materials. Feel the wood before and after rubbing it hard. Do you notice a change in temperature? If so, what? Do the same with the nail. Feel the nail before and after hammering it. Do you notice a change in temperature? If so, what? For the last answer, think about the changes you described in both the wood and the nail and tell me what caused these changes. Use this information to help you understand the point of this experiment and the questions being asked. :)
