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 activity, learners heat and cool carbonated water to find out whether temperature has an effect on how fast the dissolved gas leaves carbonated water.

This is a chemistry lab activity about solutions (page 6 of the PDF). Students make a limewater testing solution for carbon dioxide and explore the concepts of solubility and precipitates.

In this activity (on page 8), learners model how marble statues and buildings are affected by acid rain.

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

In this simple activity, learners see the production of a gas, which visibly fills up a balloon placed over the neck of a bottle.

In this activity, learners discover if carbon dioxide has an effect on temperature.

In this activity, learners imagine what the world might look like if we could build an elevator to space!

In this activity, learners explore how acids can dissolve eggshells leaving behind a membrane-covered bouncy egg.

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.

In this activity, learners test what happens when they put baking power on different frozen liquids.

Heat makes some materials expand, and it makes others shrink.

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.

In this activity, learners build models of comets, using edible materials, to learn about comets' structure.
