ACTIVITY TIME: 20-30 minutes

TOTAL PROJECT TIME: 45 minutes to 1 hour

KEY WORDS: Solar energy, solar power, sun, heat, cooking, recycling

Materials

  • Pizza box or shoe box. The larger the box, the better the oven should work.(We used shoe box)
  • Pencil or pen
  • Ruler
  • White school glue
  • A sheet of black paper
  • Utility knife
  • Aluminum foil
  • Plastic wrap
  • Shipping tape or black electrical tape
  • A wooden skewer or pencil
  • To do some cooking with your solar oven, you will need sunlight and fairly warm outside temperatures (above 75 degrees Fahrenheit is recommended, and the hotter it is the better). It should also not be windy.
  • If you want to cook some s’mores in your solar oven, you will also need graham crackers, marshmallows, and a chocolate bar. You can use an aluminum pie pan or a small piece of aluminum foil as a tray.

Prep Work

  1. If needed, clean out the pizza box so it is ready to become a solar oven. Remove any cardboard liner that the box came with.
  2. Adult assistance is recommended for using the utility knife. Use caution when cooking with the solar oven as it can get quite hot!

Instructions

  1. On the top of the pizza box’s lid,firstly,draw a square that is about one inch inward from each edge.

a) And use a utility knife (and the ruler as a straightedge) to carefully cut along each side of the square you just drew except for the side that runs along the hinge of the box and Cut all the way through the cardboard on those three sides of the square. Then fold the flap back slightly along the attached side.

b) Line the inside of the cardboard flap with aluminum foil. Besides,fold the edges of the foil over the flap to help hold the foil in place and glue the foil onto the flap. Keep the foil as smooth as possible.

c) Cover the opening made by the flap (in the lid) with a layer of plastic wrap. And attach the plastic wrap to the opening’s edges using shipping tape or black electrical tape. Make sure there are no holes in the plastic wrap, and that all of its edges are completely closed onto the lid.So,why do you think it is important to make sure the plastic wrap completely seals the lid’s opening?

d) Line the inside of the box with aluminum foil so that when you shut the box, the entire interior is coated with foil. It is easiest to do this by covering the bottom of the box with foil, and then the covering the inside part of the lid (going around the plastic-covered opening) with foil too.At last,glue the foil in place. 

e) Glue or tape a sheet of black paper to the bottom of the box and centered there. And this will act as your solar oven’s heat sink.

f) Lastly, use a wooden skewer or pencil (and some tape) to prop the solar oven’s lid up, at about a 90 degree angle from the rest of the box. Finally,your solar oven is ready to do some cooking!
