The demonstration/experiment provides quick proof that air has mass.

Learners will understand the relationship between climate change and sea-level rise.

In this activity, learners conduct an experiment to find out if steel wool will weigh more or less when it is burned. Learners will explore the effects of oxidation and rusting on the steel wool.

In this activity, learners investigate convection by using food coloring and water of different temperatures.

In this physics activity (page 6 of the PDF), learners will demonstrate air has weight by comparing an inflated balloon to a deflated one.

Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.

Learners color and cut out a spiral-shaped snake. When they hang their snake over a radiator, the snake spins.
