Sunlight Is Energy
The sun does not just give us light. It sends energy to Earth! That energy travels 93 million miles through space and reaches us as light and heat.
You can feel solar energy every time you step into sunshine on a warm day. Dark surfaces absorb more sunlight and get hotter. That is why a black car gets much hotter than a white car on a sunny day.
Today you are going to capture that solar energy and use it to cook food! Solar ovens work by trapping sunlight inside a box and converting it to heat. People around the world use solar ovens to cook food without electricity or fuel.
