How Do You Build A Classroom Wind Generator?
A wind generator, or turbine, uses the power of the wind to generate electricity. A rod connects turbines to a generator. When the wind causes the turbine to spin, this motion generates an electrical current. Ideally, it takes winds of at least 15 MPH to generate electricity efficiently. Stronger winds will generate a higher voltage so the speed of the wind determines how much electricity the turbine can generate. Building a small turbine in a classroom setting can effectively demonstrate this process to students. Put on a pair of goggles. Attach a small electric motor to the end of a ruler. The shaft should be placed along the edge of the ruler. Use a rubber band to secure the motor. Connect two wires to the motor. Attach the wires to outlets on the motor. Place insulated alligator clips on the other ends of the wires and attach the clips to a DC voltage meter. Straighten the lower half of four paper clips. The inner hook should remain intact. Trim the straightened end of the paper cl
