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.

In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.

In this simulation, learners explore how ocean currents spread all kinds of pollution—including oil spills, sewage, pesticides and factory waste—far beyond where the pollution originates.

DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique. This activity allows you to see long, stringy strands of DNA extracted from wheat germ.

In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.

In this activity, learners explore a bucket of sand and beach objects.

In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

In this activity, learners discover how a cabbage juice indicator helps identify acids and bases, and how iodine indicates the presence of starch.

In this activity, learners make balloon models of disease-causing bacteria.

In this activity, learners explore the different salinities of various sources of water by taste-testing.

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

Learners use a simple process to extract DNA from strawberries.
