Do you think you can design a wind turbine that supplies energy to 400 homes at the highest efficiency and lowest cost? Try your hand at turbine design in this interactive activity that allows you design, build, and test a device to...

Design, build, and test an energy efficient wind turbine that will supply 400 homes with electricity for one year.

Using a voltage sensor, students will measure how much "electricity" is produced by the wind turbine that they design and build. Students will experiment with blade designs to see which one collects energy from the wind the most...
