This hydroelectricity working model effectively demonstrates the basic principles of hydroelectric power generation in a simple and hands-on manner.
How It Works:
- When water flows over the turbine, it causes the shaft of the DC motor to spin.
- The spinning shaft generates electricity in the DC motor.
- This electricity powers the LED lights, demonstrating how hydroelectric power works.
Creating a hydroelectricity working model using a plastic bottle, DC motor, bottle caps, and LED lights is a great way to understand how hydroelectric power is generated.
Here’s a simple model:
Materials Needed:
- Plastic bottle
- DC motor
- Bottle caps (2 or more)
- LED lights
- Wires
- Water
- Hot glue gun or strong adhesive
- Wooden stick or dowel
- Small plastic container
- Battery holder (optional)
Steps by Steps Video Instructions:
1. Prepare the Plastic Bottle:
- Cut the plastic bottle in half horizontally to create two parts: upper and lower.
- Keep the upper part intact as the turbine and generator housing.
- Cut the bottom part to create a shallow basin for water collection.
2. Mount the DC Motor:
- Glue the DC motor to the center of the bottle cap.
- Attach a small plastic container to the shaft of the DC motor to act as the turbine.
- Ensure that the turbine can spin freely.
3. Create the Water Flow:
- Position the lower part of the bottle beneath the turbine.
- Fill the basin with water.
- Allow the water to flow from the basin to the turbine.
4. Connect the LED Lights:
- Attach the LED lights to the top of the bottle cap.
- Connect one terminal of the LED lights to one terminal of the DC motor.
- Connect the other terminal of the LED lights to the other terminal of the DC motor.
5. Test the Model:
- Turn on the DC motor by spinning the turbine.
- As the turbine spins, it generates electricity, lighting up the LED lights.
- Observe the relationship between the water flow and the electricity generated.
