Earth Hour is a new environmental science after-school program for school age children. During our first program at Queens Library at Broadway, we discussed how electricity is made, and different forms of energy including fossil fuels and renewable sources.
We also built a hand-cranked dynamo that powers a green LED. The children really enjoyed building the dynamo and learned a lot about the electricity we use in the process.
