Hand-Cranked Power Generator

Turn motion into electricity with the Hand-Cranked Power Generator experiment! In this hands-on STEM activity, kids build a simple generator that lights up a bulb or powers a small device using only the energy from turning a crank. As they see their movement create real power, they’ll learn about energy conversion, electromagnetism, and how mechanical energy transforms into electrical energy—a fun and empowering way to explore the science behind renewable energy and generators!
