Cut a piece of aluminum foil large enough to cover the inner side of the cardboard flap.
Wrap the foil tightly, and secure with tape. What purpose does the foil serve?
Line the bottom of the pizza box with black construction paper. What purpose does the black paper serve? Would white paper work as well? Why or why not?
Cut two pieces of plastic wrap that are the same size as the top of the pizza box.
Use tape to secure the plastic wrap to the inside edges of the square window you cut into the box. You are creating an airtight window. Why do you want to make your oven airtight?
Roll up some newspaper pages into tubes to stuff into the sides of the box. Make sure you are still able to close the lid of the pizza box. Remember—what purpose does the newspaper serve?
Now it is time to cook something! The best time to use your oven is between 11 AM and 2 PM. Make sure to set the food on a dish so you don’t mess up the interior of your oven.
One food option is a solar s’more. Place one or two marshmallows on top of a graham cracker. Put two to three squares of chocolate on top of the marshmallow. Wait until it’s done cooking to top it with the second graham cracker. Any idea why it might be smart to have the chocolate on top?
You could also make nachos by placing grated cheese on top of tortilla chips, or use the oven to heat up leftovers or soup.
