Air and Temperature

Procedure (cont.)

6. Discuss students’ predictions about the behavior of warm and cool air, in light of their observations. Ask, What do you think will happen if we heat the air in the can even more? In a demonstration area, dip another can in bubble solution; then heat it using a lighted candle, hotplate, warm towel, etc. (The bubble will bulge much more dramatically than students saw in their previous trials.)

7. Discuss the students’ discoveries about air movement and encourage them to think about what might be happening with the air inside the classroom. Ask, What happened to the air inside the can when it was placed in cold water? In warm water? Follow by encouraging a general discussion. Ask, Where are the sources of different air temperatures in the room? What will happen if the air in one part of the room is warmer than air in other parts?
