Let the energy blow. Using mostly easily found material such as PVC pipe and fans, pupils build wind turbines. Scholars connect a multimeter to an electric motor to determine the amount of energy generated by their designs. Learners then compare the energy output for different speeds of wind and blade designs.

Instructional Ideas

• Have individuals create multiple blade designs and test to determine the best design for creating energy
• Research commercial wind turbines and how they store energy

Classroom Considerations

• Requires a motor, a hub, and a multimeter along with other basic materials

Pros

• Includes a link to locate materials that are difficult to find
• Contains background information of wind and wind turbines

Cons

• None
