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

In this activity, learners sublimate dry ice and then taste the carbon dioxide gas.

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

In this chemistry activity, learners use common chemicals to produce carbon dioxide and observe its properties. This resource includes brief questions for learners to answer after the experiment.

In this activity, learners make a yeast-air balloon to get a better idea of what yeast can do. Learners discover that the purpose of leaveners like yeast is to produce the gas that makes bread rise.

In this chemistry activity, learners use common chemicals and metals to examine reactions that produce gaseous substances.

"Sublimation Bubbles" allows learners to explore how some solid materials, such as dry ice, can phase change directly from their solid to gaseous form.
