What We Built
Build your own flashlight by turning physical motion into bright, portable electric power!
What We Learned
Energy Conversion
Students discovered how manual movement is transformed into usable electricity using magnets and wire coils.
Gear Mechanics
They analyzed how different gear sizes impact speed versus torque to optimize mechanical power.
Hands-on Assembly:
Participants practiced precision woodworking and circuitry skills to build a functional, self-powered device.
Skills Practiced
- Circuitry
- Woodworking
- Mechanical Assembly
- Gear Manipulation
- Problem Solving
Build Structure
The Challenge
Generate enough power to light an LED by hand.
The Process
Assemble gears and a generator into a housing.
The Result
A fully functional, battery-free flashlight.

Ask Your Camper
- How did spinning the crank make the light turn on?
- Why do we need gears inside the flashlight?
- Can you explain the difference between speed and torque?
Extend At Home
- Explore gear ratios on your bike, or play "Gear Hunt" at home! Find items like egg beaters or clocks, then guess if their gears prioritize speed or power.
