In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.

In this activity, learners build a simple qualitative conductivity tester with a battery, bulb and foil.

In this activity, learners can create five-layer density columns by employing one of three (or all) methods.

In this chemistry meets cooking activity, learners compare the stability of egg white foams with various additives.

In this activity, learners construct a device out of a piezoelectric igniter, like those used as barbecue lighters.

This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer.

In this activity, learners build a simple electrolysis device. Then learners use an indicating solution to visualize hydrogen and oxygen molecules in water.

Why does milk make some people sick? In this activity learners explore this question and explore the chemistry of milk, and our bodies!

In this activity, sodium acetate hand warmers are used to introduce learners to supersaturated solutions, crystallization, and exothermic reactions.

In this activity, learners use gelatin as a lens to investigate the properties of laser light.

In this activity, learners construct a simple electrolysis device. With this device, learners can decompose water into its elemental components: hydrogen and oxygen gas.
