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

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 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.

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

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

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