Build a Solar Oven

Solar ovens use the energy from the sun to warm and cook food, saving energy that would normally be used to heat up your oven. Plus, they are just cool.
I made these solar ovens with my environmental science class last semester and we used them to heat up s'mores. It totally worked, and the day was mostly cloudy! I can only imagine the potential of a warm summer day! These ovens can get up to 200 degress!
This is a great project to do with children. Plan on making s'mores, an english muffin pizza, or some other tasty treat in them!

Supplies & Tools:
• 1 used pizza box
• newspapers
• scissors
• tape
• black construction paper
• clear plastic wrap
• aluminum foil
• ruler, pencil, stick or something to prop box up with

Directions:
1. Draw an 8 1/2 inch x 11 inch square in the lid of the pizza 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 if needed.
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.
