Hand crank electric generator

This little electric generator may be used in a variety of contexts, from a cause and effect activity (turning a light on), a science lesson (how electricity is produced), or recharging a cell phone / tablet.  Students can literally feel the work needed to power modern electronics, lights, fans, etc.
Cost: the hand crank generator was approximately $20, materials (scrap wood, adjustable bracket, screws): approximately $5
