This kinesthetic, color-coded simulation helps students visualize how an action potential travels down a neuron.

Done as a whole-class, students move pom-pom "ions" across a membrane to simulate how an action potential is propagated along an axon.

Pom Pom Potential Print-and-Go

Color Overheads Only
