In this activity, learners conduct tests for proteins, glucose, and starch.

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

In this activity that can be used as a lab or demonstration, learners use Lactaid® and lactose to demonstrate the concept of enzyme action.

In this activity, learners conduct a controlled experiment to examine how temperature will affect the height of a soda geyser.

In this open-ended multicultural lab activity, learners investigate the effectiveness of herbal remedies.

This lesson is designed to serve as an introduction to the immune system. It can stand alone or it can lead into further studies of the immune system.

This three-part lab helps learners understand the essential principles governing diffusion and osmosis.

In this activity, learners will be introduced to biomass gasification and will generate their own biomass gases.
