Demonstrates Seven Photovoltaic Experiments.
Create awareness for environmentally-friendly energy sources at an early age with this fun and educational solar-powered stick and propeller. Solar energy is stored in the 1.5 V solar panel that is attached to a stick made of renewable resource wood, sending power to gears that rotate a propeller blade. Students are introduced to the many uses for photovoltaic energy through experimentation with the stick as a fan, carousel, mobile, gear system, and alarm device. Includes wood stick with integrated solar motor, solar panel, gear wheel, propeller, buzzer, lamp, cable, and wood wheel for creating optical illusions. A detailed instruction manual is included.
