This project involves seventh and or eighth grade students working in teams to build fully functioning windmills. They develop an understanding and awareness for wind energy sources, as well as a sense of sustainable energy. Students begin the unit by designing a weightlifting windmill out of a variety of supplied materials. They compete to see who can lift the most washers. Then, they do an inquiry activity to determine who can build the turbine that can produce the most volts. They experiment with number of blades, blade pitch, blade shape etc. A classroom competition is the culminating event for the unit.
