In this activity, learners play a simple card game to learn the sequence of events in the transmission of nervous system signals.

In this food science activity, learners explore digestion and proteins by observing the action of meat tenderizer on luncheon meat.

In this neuroscience activity, learners conduct a simulation to demonstrate how multiple incoming signals influence the action of neurons.

In this activity, learners play a simple card game to learn the sequence of events in the transmission of nervous system signals.

In this activity, learners estimate risks associated with different events and compare their estimates to the real possibilities.

In this nutrition activity, learners explore food labels and consider the nutritional value of foods. Learners also explore units of measurement commonly used on food labels.

In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.

In this activity, learners compare and contrast their own skin (including the area covered) with that of an orange.

In this environmental health activity, learners investigate their breathing and pulse rates, and learn how these measurements are affected by physical activity.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

This is a series of quick activities/demos and pre-assessment tools that evaluate learners' current understanding of microbes and introduce them to basic information about microbes.

This activity helps learners visualize the Human Immunodeficiency Virus (HIV) by constructing three-dimensional HIV particle models from paper.

This neuroscience activity introduces learners to how messages are sent and received by neurons. Learners use modeling clay and pipe cleaners to build model neurons.

In this activity, learners act as epidemiologists by mapping the prevalence of HIV/AIDS worldwide.

In this environmental health activity, learners investigate their own vital lung capacities.

In this activity, learners dissect a piece of pizza to learn about nutrients important for health.

In this food science activity, learners observe different plant-originated foods.

In this environmental health activity, learners grow and observe bread mold and other kinds of common fungi over the course of 3-7 days.

In this four-day activity, learners grow bacteria and/or fungi from a variety of locations and compare the results.

In this activity, learners use sets of cards to assign microorganisms to different groups.
