Hand Crank Generator School Project Kit

Turn the crank and the light comes on. No batteries anywhere in this hand crank generator, which is what makes the point: the electricity is coming from the learner's arm, through a geared motor working backwards as a generator.

What your learner works with

• A crank and gear train mounted on a base
• A motor running in reverse as a generator
• The relationship between how fast you turn and how bright the output
• Energy conversion from mechanical to electrical, which they can feel in the resistance of the handle
