Supplies

For this project you will need some things that you likely already have on hand.
- Box with flip top lid (pizza, doughnut, shoe, etc.)
- aluminum foil
- plastic wrap or page protector
- bamboo skewer
- Tape
- scissors
- pencil
- ruler
- (Whatever you want to cook in your oven. We did s’mores.)
Instructions

Take a look at your box. It is going to have a window in the lid to allow the sun to come in. Using your ruler mark three sides of your window. Left, Right, and bottom. You want your window to be large. Leave about 1 -2 inches of box around the perimeter.
Using your scissors to cut the lid on three sides to create a flap in the lid. Fold the cut flap on the lid back.

Line the inside bottom of the box with aluminum foil. Also, attach aluminum foil to the underside of the cut flap on the lid to reflect sunlight into the box.
Now, attach the plastic wrap or page protector to the opening in the lid using tape. This will create a window.

Poke a hole through the lid of the box to lean against the cut flap to hold the flap up.
Your oven is ready to rock!
How to Use

Now that you have made your oven it is time to get cooking. You need to find a sunny spot in your yard. Set your oven on a small table or on a blanket.
We chose to make s’mores in ours.
Place the graham crackers inside the box with a piece of chocolate bar and a marshmallow on top. Close the box and position the box to face the sun with the flap up. The chocolate will melt quickly. The marshmallow will soften but it will take longer.
When the marshmallow is soft enough, press another graham cracker square against the top of the s’more. Enjoy!
Science
This is so cool, but how does it work?
Some fun key concepts in this project are learning about heatwaves, the sun, even recycling.
As simply as possible the aluminum foil reflects the heat waves onto the item in the box. The box helps to contain the heat cooking the item. I suggest getting your kids involved in some online research or hitting your local library to dig up some info on heatwaves and solar to turn this into a fun learning experience.
These work so well that they actually sell solar ovens on Amazon for camping and more. Check them out.
