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.

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

Ocean acidification is a problem that humans will have to deal with as we release more and more carbon dioxide into the atmosphere.

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.
