In this activity, learners investigate vitamin C.

This guide outlines how to plant a garden even if you don't have a yard!

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, learners make self-assembled polymer spheres.

In this activity, learners use molecular model kits to construct familiar molecules like lactose, caffeine, and Aspirin.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

Many germs spread by our hands, and often times, people don't wash their hands well enough to get rid of germs.

Learners use Benedict’s solution and heat to test for the presence of simple sugars in glucose, sucrose, starch, and starch combined with amylase.

This experiment allows learners to experience a small scale "epidemic," demonstrating the ease with which disease organisms are spread, and enables learners to determine the originator of the "epidemi
