Potentially the most complex and difficult concept to teach in the nervous system unit is signal transduction and action potentials across the axons of neurons. This activity has the students use different types of beans to represent the three major ions (potassium, calcium, and sodium) involved in the actino potential. I've had mixed results with this activity, but it is very useful with students who are more hands-on tactile learners grasp a very abstract concept.
