5 Ideas for Experiments on Conserving Energy

Author's Note: 5 Ideas for Experiments on Conserving Energy

These experiments are intended to teach us about energy conservation principles, but they can suggest practical applications as well. For example, my neighbor has a swimming pool. In the spring, he takes a long length of garden hose and lays loops of it on the roof of his south-facing pool house. It's a lot like the solar hot water experiment. During the day, he uses a pump to run water from the pool through the hose and back in. Solar energy lets him keep his pool a comfortable temperature and he gets into the water earlier than anybody else.
