Grade 4 Lesson: Wind-powered LED

The landscape is changing as we find alternative ways to meet our energy needs and rely less on fossil fuels. Hydropower from dams, wind power, solar power, wave energy, and even methane gas from sewage and anaerobic digestion processes are all examples of renewable, alternative energy sources that engineers are harnessing. Students will learn about one of these renewable energy sources as they design a wind turbine. They will test blade designs on a windmill and see if it can light an LED light bulb.
