Description
Harness the power of the sun! A powerful solar cell and motor convert solar energy into electrical energy, then into mechanical energy. Place the solar cell in direct sunlight and immediately the motor spindle turns. Attach the propeller to create a solar fan; use the colorful disc to make a fun visual effect.
The sensitive solar cell lets students study the variables that affect power output, such as light intensity, light angle, and cell surface area.
Includes a propeller, reflective disc, spiral disc, and 24-page booklet of information and activities.
