Experiment with wind energy in this SciGirls activity that challenges students to build their own weight lifting wind turbine. Windmills have been used for thousands of years to grind grain, pump water, and even generate electricity. They lost popularity as new sources of energy, such as fossil fuels, arose. But the idea of using wind for energy has made a comeback in recent decades, and careers in wind energy are growing rapidly as the demand for clean energy increases.
