Project
Harnessing sunlight is key to solving future energy challenges. In devices like solar cookers, mirrors are used to converge sunlight and generate heat. Think of a design for a solar cooker for your school or home and prepare a detailed proposal for it including the budget required.

Key Points
Use a concave reflector to focus sunlight onto the pot.
Key Points / Good Practices
- Use a curved (concave) reflecting surface to converge sunlight.
- Place the cooking pot at the focus point where light gathers.
- Use an insulated box to trap the heat.
- List materials: reflector, box, glass cover, black pot.
- Estimate the cost of each material for the budget.
- Explain how it saves electricity and fuel.
A good proposal uses a concave reflector to focus sunlight onto a pot, with a clear materials budget.
