Hand-Crank Generator Activity Kit

Students won't have to take your word for it that electricity is a transfer of energy — they will feel it!

With this simple classroom activity, your students will directly understand the concept of electricity as transfer of energy. Students will provide the energy by operating the Hand-Crank Generator, and see the resulting transfer of mechanical energy into light. And they will truly feel the difference in effort between lighting no bulbs, one or two bulbs.
