Experiment with wind power - a renewable energy source. The solar motor is powered by the wind and can provide energy to other projects - like powering up the included light bulb. Take the kit apart and build it again in the next class. Adjust the gearings and you can increase the motor speed. Students can also experiment with the number, angle, size and shape of the blades. If there is no wind, you can use the orange finger spinner for testing purposes. Requires blower for indoor experiments.
