Introduction
This working model demonstrates how solar and wind energy can power two houses, showcasing the importance of renewable energy sources in reducing dependence on fossil fuels. It highlights the practical use of solar panels and wind turbines to generate electricity.
Materials Required
- Cardboard (for making two house models)
- Small solar panels (to generate electricity from sunlight)
- Mini DC motor with fan blades (to act as a wind turbine)
- LED lights (to show electricity generation)
- Wires & connectors
- Battery (optional, for storage of energy)
- Glue, scissors, and color paper for decoration
Model Setup
- Houses Construction:
- Build two houses using cardboard.
- Place one solar panel on the roof of one house.
- Install a wind turbine near the second house.
- Solar Energy Demonstration:
- Connect the solar panel to an LED light in one house.
- When exposed to sunlight (or a flashlight), the LED will glow, showing power generation.
- Wind Energy Demonstration:
- Attach the DC motor with fan blades near the second house.
- When you blow air (or use a small fan), the wind turbine will generate electricity to power the LED light in the second house.
- Storage Option (Battery Backup – Optional):
- Connect the solar panel and wind turbine to a small rechargeable battery.
- This will store energy and keep the LEDs glowing even when the wind stops or there’s no sunlight.
Key Learning Points:
- Solar panels convert sunlight into electricity.
- Wind turbines generate power from moving air.
- Both energy sources can be combined to create an efficient renewable energy system.
- This model demonstrates how sustainable energy can be used in real homes.
