In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

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

In this activity, learners observe as soap bubbles float on a cushion of carbon dioxide gas. Learners blow bubbles into an aquarium filled with a slab of dry ice.

In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.
