How can we generate electricity when the power goes out using nothing more than movement, magnets, and copper wire?
In this hands-on workshop, students will explore how electricity can be generated using simple mechanical systems before designing and building their own hand-cranked emergency torch. Using motors, magnets, copper wire, and basic electronic components, they'll discover how movement can be converted into electrical energy to power a light without batteries.
As they build, students will investigate how electric motors and generators work, using multimeters to measure the electricity they produce. They'll experiment with different speeds, observe how these affect electrical output, and apply their findings to construct a functional hand-powered torch.
This workshop combines engineering, electronics, and problem solving in an engaging challenge that introduces students to the principles of electricity generation, energy conversion, and emergency preparedness.
