📚 Part 1: Multiple Choice

1. Which of the following is NOT a renewable energy source?

Solar

Wind

Hydro

Coal

2. How does a wind turbine generate electricity?

Sunlight heats the blades which produce current

Wind turns blades connected to a generator

Heat from deep underground turns the blades

Flowing water pushes the blades directly to light bulbs

3. Which New Zealand town is well known for geothermal energy?

Rotorua

Wellington

Christchurch

Dunedin

4. Check all true benefits of renewable energy compared with fossil fuels:

Produces fewer greenhouse gas emissions

Renewable — will not run out quickly

Causes oil spills when extracted

Produces large amounts of carbon dioxide in regular use

✏️ Part 2: Short Answers & Observations

5. In one sentence, write what "energy conversion" means:

6. How does a simple solar oven model trap and increase heat inside the box? (2–3 lines)

7. Observation calculation: A thermometer inside a solar oven reads 18°C at 10:00 and 35°C at 10:15 during testing. a) What is the temperature increase? b) What is the average increase per minute? Show working.

8. Suggest one practical change your group could make to a wind turbine model to increase blade rotation. Explain why it would help.

🎨 Part 3: Design & Reflect

9. Draw and label a simple model: choose either a wind turbine or a solar oven. Include labels for: the energy source, where conversion happens, and the useful output.

10. In one sentence, which renewable energy would you choose to help power your school in New Zealand and why?
