This multimedia collection crosses the curriculum between Biology and Physics as students model signal transmission along an "axon" by sending a small electric current through a vinyl tube filled with salted gelatin. The lesson plan was inspired by "Bridging Physics and Biology Using Resistance and Axons", an article in The Physics Teacher magazine. The support materials provide related video, content support in neural science and fundamentals of electric current, links to interactive animations, and examples of how the science is applied by scientists and doctors in real life.
