POM POM POTENTIAL
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.
Neuron, axon, membrane structure, carrier proteins, ions
