Building a Solar Oven

The video introduces the concept of solar ovens, which use solar energy to cook food outdoors. It guides viewers through designing a solar oven using a pizza box, tin foil, and plastic wrap. The video addresses design challenges like maximizing sunlight entry and choosing the right plate color for effective heating. It concludes with testing the solar oven and suggesting improvements, encouraging viewers to experiment with their designs.

What is the primary energy source for a solar oven?

• Solar energy

• Wind energy

• Gas

• Electricity

What material is suggested to use as the main box for the solar oven?
