A solar oven uses energy from the sun to cook food. The diagram shows a solar oven made from a pizza box. When food is placed in the box, the sun’s energy reflecting off the aluminum foil helps heat the food.

Which experiment would determine the best material to use for the liner?

• Place four different materials in the bottom of the box one at a time. Measure the temperature inside the box after each material has been in the box for 5 minutes.

• Place one material in the bottom of the box. Measure the air temperature inside the box after the material has been in the box for 5 minutes.

• Place four different materials in the bottom of the box one at a time. Measure the air temperature outside the box after each material has been in the box for 5 minutes.

• Place one material in the bottom of the box. Measure the air temperature outside the box after the material has been in the box for 5 minutes.
