Equipment and Material
• 1 pizza box
• newspapers
• scissors
• tape
• black construction paper
• clear plastic wrap
• aluminum foil
• ruler
Method
1. Draw an 8 1/2 inch x 11 inch square in the
lid of the assembled box.
2. Cut out three sides of the square, and fold
the flap back along the uncut edge.
3. Cover the inside of this flap with aluminum
foil, using tape to hold the edges securely.
4. Line the inside bottom of the box with black
construction paper. Use tape to hold the edges down.
5. Create insulation by rolling up some newspaper (about 1 1/2
inch thick) and fitting it around the inside edges of the box.
6. Tape one piece of plastic wrap (stretched tightly) to the underside
of the lid opening, to cover. Tape another piece on the top of the lid opening, to create a layer of
insulation that will help hold the heat in the box.
7. Prop the box at an angle facing the sun. Use a ruler to prop the flap open.
On a hot, sunny day the temperature can reach 200°°F in
your oven! Use it to make smores, or to warm some muffins.
