Learners observe an electrochemical cell constructed from a small jar containing zinc and copper strips immersed in separate solutions. The strips are connected to a motor that turns a small fan.

In this activity, learners create a soil and water model of a single-cell life environment and study living microorganisms.

In this kinesthetic activity, learners move pom-pom "ions" across a membrane to simulate how an action potential is propagated along an axon.

This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells using simple materials.
