Energy worksheet for learning about energy sources and their uses.

Let's solve this worksheet step by step.

---

A) Do they give energy or use energy?

We need to determine whether each object gives (produces/outputs) energy or uses (consumes) energy.

1. The sun gives / uses energy.
✔ Gives – The sun produces energy through nuclear fusion and radiates it into space.

2. The electric fan gives / uses energy.
✔ Uses – The fan needs electricity to operate; it converts electrical energy into kinetic energy (motion).

3. The iron gives / uses energy.
✔ Uses – The iron requires electricity to heat up and function.

4. The oil gives / uses energy.
✔ Gives – Oil is a fuel source; when burned, it releases energy (e.g., in engines or heating).

5. The plane gives / uses energy.
✔ Uses – A plane uses fuel (like gasoline or jet fuel) to generate motion and fly.

6. The coal gives / uses energy.
✔ Gives – Coal is a fossil fuel that releases energy when burned.

B) Look at the pictures and match. What do they give energy to?

Now we match the sources of energy (listed on top: 1–6) with the things that receive energy (the images below).

Let’s analyze each image:

#### Image 1: Smartphone in hand
- This phone has a battery.
- It uses energy from batteries.
- So, batteries → smartphone.

✔ Match: 5) batteries

#### Image 2: Electric iron
- The iron runs on electricity.
- It uses electricity to heat up.

✔ Match: 6) electricity

#### Image 3: House with solar panels
- Solar panels capture sunlight to produce electricity.
- So, sun → house (via solar panels)

✔ Match: 1) sun

#### Image 4: School bus
- A bus runs on gasoline (fuel).
- So, gasoline → bus

✔ Match: 2) gasoline

#### Image 5: Runner on track
- The runner uses food as energy to run.
- Food provides chemical energy for muscles.

✔ Match: 3) food

#### Image 6: Pot boiling over fire
- Fire heats the pot and cooks food.
- So, fire → pot/cooking

✔ Match: 4) fire

✔ Final Matching for Part B:

| Picture | Matches to |
|--------|------------|
| Smartphone | 5) batteries |
| Iron | 6) electricity |
| House with solar panels | 1) sun |
| School bus | 2) gasoline |
| Runner | 3) food |
| Pot over fire | 4) fire |

✔ Summary of Answers:

#### A)
1. gives
2. uses
3. uses
4. gives
5. uses
6. gives

#### B)
- Smartphone → 5) batteries
- Iron → 6) electricity
- House with solar panels → 1) sun
- School bus → 2) gasoline
- Runner → 3) food
- Pot over fire → 4) fire
