Students are designing a solar oven that can be made from materials found in their homes. Solar ovens take more time to heat food than regular ovens. The students would like to build a solar oven that heats food as quickly as possible. Which TWO characteristics should the students consider when addressing the time the oven takes to heat food?

• How often the oven will be used to heat food

• the type of food that will be heated in the oven

• possible ways of preventing or reducing the loss of heat from the oven

• constructing an oven that is portable and easy to transport from place to place

• designing an oven that will collect as much sunlight and absorb as much heat as possible
