“This is a hydroelectric power generation model.Water stored in the dam flows through a pipe and hits the turbine. The turbine spins a generator (DC motor), which produces electricity.
This electricity is carried through transmission lines supported by power poles to homes, factories, and cities.
Hydroelectricity is a clean, renewable source of energy.
Concept Explanation:
Hydroelectricity is generated by water stored at a height, which falls and spins a turbine connected to a generator (motor). This electricity is then transmitted through wires using power poles to homes and cities.
Step-by-Step Model Building:
1. Build the Dam & Mountain
- Create a mountain using layered cardboard or thermocol.
- Fix a plastic bottle or syringe at the top (water reservoir).
- Add a pipe or straw to let water flow down.
2. Install Turbine & Motor
- At the base of the mountain, fix a turbine blade (cut from bottle).
- Connect it to a DC motor. When water hits the turbine, it spins and rotates the motor shaft.
3. Generate & Show Power
- Connect the DC motor terminals to an LED bulb.
- Water flow spins the turbine → turns motor → LED glows.
4. Add Transmission Lines
- Create 3–4 power poles using skewers, paper straws, or sticks.
- Use thread, black wire, or thin wire to create transmission lines.
- Connect the end of the wire to a small cardboard house, showing electricity is reaching homes.
5. Decorate the Setup
- Paint the river with blue color.
- Add green paper for grass/trees.
- Use yellow LEDs for homes.
