1. WINDMILL

- What happens? Wind (moving air) turns the blades of the windmill, which can generate electricity.
- Energy transformation:
- Kinetic energy (wind) → Mechanical energy (rotation of blades) → Electrical energy (if connected to a generator)

> ✔ Answer:
> Wind (kinetic) energy → Mechanical energy → Electrical energy

---

2. TORCH (Flashlight)

- What happens? A battery powers a bulb or LED, producing light.
- Energy transformation:
- Chemical energy (in battery) → Electrical energy → Light energy (and some heat)

> ✔ Answer:
> Chemical energy → Electrical energy → Light energy

---

3. MICROWAVE

- What happens? Electricity heats food using electromagnetic waves (microwaves).
- Energy transformation:
- Electrical energy → Microwave (electromagnetic) energy → Thermal (heat) energy

> ✔ Answer:
> Electrical energy → Thermal energy (via microwave radiation)

---

4. DYNAMITE

- What happens? When detonated, dynamite releases a large amount of energy in an explosion.
- Energy transformation:
- Chemical energy (stored in explosives) → Heat energy + Sound energy + Kinetic energy (shock wave)

> ✔ Answer:
> Chemical energy → Heat energy + Sound energy + Kinetic energy

---

5. BICYCLE

- What happens? A person pedals, converting their body energy into motion.
- Energy transformation:
- Chemical energy (from food) → Muscular (mechanical) energy → Kinetic energy (motion of bicycle)

> ✔ Answer:
> Chemical energy → Mechanical energy → Kinetic energy

---

6. BATTERY

- What happens? A battery stores chemical energy and converts it to electrical energy when used.
- Energy transformation:
- Chemical energy → Electrical energy

> ✔ Answer:
> Chemical energy → Electrical energy

Final Answers:

| Image | Energy Conversion |
|-------------|-------------------|
| WINDMILL | Wind (kinetic) → Mechanical → Electrical |
| TORCH | Chemical → Electrical → Light |
| MICROWAVE | Electrical → Thermal (via microwaves) |
| DYNAMITE | Chemical → Heat + Sound + Kinetic |
| BICYCLE | Chemical → Mechanical → Kinetic |
| BATTERY | Chemical → Electrical |

✔ Summary of Energy Conversions:

1. Windmill: Kinetic → Mechanical → Electrical
2. Torch: Chemical → Electrical → Light
3. Microwave: Electrical → Thermal
4. Dynamite: Chemical → Heat + Sound + Kinetic
5. Bicycle: Chemical → Mechanical → Kinetic
6. Battery: Chemical → Electrical

These are the correct energy transformations for each device shown in the worksheet.
