Students see how the movement of wind can be used to produce other kinds of energy.
People have been using wind as a source of power for centuries. The earliest wind-powered machines used wind to drive water pumps or grain mills.
A pinwheel's blades are pushed around by the wind. It is similar to a windmill or a wind turbine. A wind turbine generator uses fan-shaped blades to catch the wind. As the blades turn, they spin a generator which drives electric current. The electric current is sent through transmission and distribution lines to a substation, then on to homes, businesses and schools.
