Heat can be transferred three ways: conduction, convection, and radiation. In the solar oven made in this activity, radiation is used to cook the s’mores. Radiation occurs when heat is transferred without the direct contact between the two objects (the sun and the s’mores).
How does the solar cooker take advantage of convection?
Convection -‐ In both the solar oven and the atmosphere heat circulates due to convection. Convection occurs when warm air, which is less dense and has a lower pressure than cold air, rises, and the colder, denser air sinks to take its place. … b) Solar oven using the sun’s light to cook food.
What are the benefits of a solar cooker?

What are the advantages of using a solar cooker?
Solar cookers benefit the environment by:
- Using clean, renewable, and readily available solar energy as fuel.
- Preserving natural resources by not requiring the use of wood or other biomass fuels to cook.
- Not producing dangerous emissions which pollute local environments and contribute to climate change.
Does a solar cooker work?
Solar cooker works on the principle that sunlight warms the pot, which is used for cooking the food. Now, this warming of the pot occurs by converting light energy to heat energy. … A solar cooker lets the UV light rays in and then transforms them into longer infrared light rays that cannot escape.
