The purpose of using a dark color item in the bottom of the box is to

• reflect the light to the marshmellow

• absorb the light and transform it to heat

• concentrate the light directly on the marshmellow

• allow the light to pass through easily

The purpose of using reflective panels is to

• reflect some of the light out the box

• absorb the heat making the box hotter

• concentrate more light onto the marshmellow

• help insulate the box so heat does not escape

Why is a tall skinny box not as effective as a short wide box?

• The window to allow heat in will be smaller.

• The heat will escape too easily.

• There is no way to angle a reflective panel into the box.

• The albedo will be too low.

Gina and Jordan want to make food for a few guests. They decide to use a solar cooker, but they haven't used one before. They will use their knowledge about energy transfer and changes in types of energy to make sure the cooker works. They will also make changes so the cooker works better. Use this information to help you answer the next 4 questions. Are you ready!

• Yes, I love science! I'm ready for the challenge!

• Don't choose this answer.

• Definitely don't choose this one.

• Please, don't choose me!
