In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.

In this chemistry activity, learners observe a combustion reaction and deduce the components necessary for the reaction to occur.

In this chemistry activity, learners use common chemicals and metals to explore single replacement reactions.

This display shows slow chemical reactions in colorful crystal formations known as Liesegang Rings. These reactions are similar to those forming the rings in agates.

In this chemistry activity, learners use common chemicals to examine reactions that occur between two aqueous solutions.

Learners combine hydrogen peroxide with three different forms of potato: raw chunks, ground chunks, and boiled chunks.

This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.
