Students observe that a change in the temperature of air can impact the size of a bubble placed on a bottle that is cooled and/or heated.

**Time**

- Teacher preparation: 20 minutes
- Introduction for students: 10 minutes
- Student activity: 30 minutes
- Class discussion/analysis: 10 minutes

**Student Learning Objectives **

- Students observe that change in temperature of the air in a bubble will change the volume of the bubble
- Students will be able to describe the relationship between the change in a unit of air's temperature to its volume
- Students will understand that the Sun's energy creates movement in the air, and that motion is called a convective current
