In this activity, learners create a water prism to break light into the seven colors of the rainbow.

In this activity, learners discover what happens when they crush wintergreen-flavored candies in a very dark room.

In this activity, learners make their own heat waves in an aquarium.

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

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 demonstration, adult learners create a lava lamp using beer and nuts! Use this pub-themed activity to demonstrate the effects of buoyancy and bubbles.

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 physics activity, learners recreate Galileo's famous experiment, in which he dropped a heavy weight and a light weight from the top of the Leaning Tower of Pisa to show that both weights fall

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.

In this chemistry lab activity, learners model the colors of fireworks by burning metallic solutions in a flame and observing the different colors produced.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.
