The Firefly Wind Wheel - Blade Investigation activity introduces students to the concepts of wind energy, mechanical energy, and electrical energy. Students build a small wind turbine that captures kinetic energy from moving air, converts it into mechanical rotation, and then into electrical energy that can power a small LED or other low-power device. This hands-on activity blends engineering design and physical science. Students experiment with blade pitch, shape, and number to see how these variables affect energy output.  

The kit is designed for 20 students (in groups of 3-4) and can be found in our Equipment Library.
