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 chemistry activity, learners use spaghetti to explore density and chemical reactions.

This activity teaches combustion as the interaction of a fuel source and oxygen.

In this activity, learners find out what happens when they cover leaves with pieces of black construction paper. This activity shows learners that plants need sunlight to survive.

Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.

In this activity, learners construct and launch rockets using simple materials and their understanding of chemical reactions.

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

Visitors mix water and sodium bicarbonate (baking soda) in a large flask. They then add citric acid to the mixture and stopper the flask. The resulting reaction creates carbon dioxide gas.
