A simple windmill or wind turbine can be made by using simple household items to understand the aerodynamics and function of a windmill. Windmills are machines that convert energy from the wind into useful work by rotating. The rotation of a windmill often powers a motor or generator used to produce electricity or mechanical work (moving objects).

Learning Outcomes

  • Understand different sources of energy and that wind is a renewable energy source.
  • Students will build a windmill to learn about wheel-and-axle machines and how these simple machines are used to do work.
