This model demonstrates how wind energy can be converted into electrical energy using a wind turbine connected to a DC motor, which powers an LED bulb to light up a cardboard house.
This model shows how wind energy is converted into electrical energy using a wind turbine connected to a DC motor. The electricity powers an LED light in a house, showing a clean and renewable energy source. Wind turbines like these are used in wind farms to generate sustainable electricity.

Materials Required:
- DC motor (small hobby motor)
- Plastic fan blades / DIY turbine blades (made from bottle or cardboard)
- 9V battery + battery connector (optional if reverse setup is needed)
- LED light (3V or similar)
- Cardboard (for base, house, and stand)
- Hot glue gun or Fevicol
- Wires (for connections)
- Paper / color paper (for decoration)
- Scissors / cutter
Video Step-by-Step Instructions:
1. Create the Wind Turbine:
- Attach plastic fan blades to the shaft of the DC motor (or cut blades from a plastic bottle/cardboard).
- Mount the motor vertically on a tall cardboard tower or stick, simulating a wind turbine pole.
2. Make the Cardboard House:
- Use cardboard to build a simple house structure.
- Inside the house, fix an LED light.
3. Connect the Circuit:
- Connect LED terminals to the output wires of the DC motor.
- When the blades spin (by wind or a fan), the motor generates electricity to light up the LED.
- Optional: If using reverse (motor powered by battery), show how motor spins the fan.
4. Demonstrate Power Generation:
- Use a handheld fan or blow air toward the blades.
- The blades spin the motor → motor generates current → LED lights up.
