This working model demonstrates how electrical energy can be converted into different forms of energy:
- Light energy using an LED
- Wind energy using a fan (motor)
- Sound energy using a buzzer
This project shows the practical applications of electrical energy in our daily lives.
Materials Required:
- 9V battery + battery clip
- LED light (3V or 5V)
- DC motor + plastic fan blade
- Buzzer
- 3 small on/off switches (one for each energy form)
- Cardboard (for base and decoration)
- Wires (for circuit connections)
- Hot glue gun / Fevicol
- Color paper and sketch pens (for labels)
Video Step-by-Step Instructions:
1. Prepare the Cardboard Base:
- Create a neat layout using cardboard for placing all three components: LED, fan, and buzzer.
2. Connect the Circuit:
Wire the components as three parallel circuits from the 9V battery:
For LED Light (Light Energy):
- Connect the LED to one switch and then to the battery.
- When the switch is on, LED glows, showing light energy.
For DC Motor + Fan Blade (Wind Energy):
- Attach a fan blade to the shaft of the DC motor.
- Connect the motor to a second switch and then to the battery.
- When switched on, fan rotates, showing wind energy generation.
For Buzzer (Sound Energy):
- Connect the buzzer to the third switch and the battery.
- On switching, buzzer produces sound, demonstrating sound energy.
3. Label Each Section:
- Clearly label: Light Energy, Wind Energy, and Sound Energy.
