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 activity, learners observe what happens when yeast cells are provided with a source of food (sugar). Red cabbage "juice" will serve as an indicator for the presence of carbon dioxide.

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

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 generates learner excitement about light through the creation of a room-sized rainbow.

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

In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar.

In this activity related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.

In this activity related to microbes, learners create scale models of microorganisms and compare relative sizes of common bacteria, viruses, fungi and protozoa using metric measures: meters, centimete
