For our Science Fair Project we decided to make a Solar Oven. We thought that the Solar Oven would heat up the food but not fully cook the food. We won’t have the right temperatures for this experiment. We kept the food we heated up/cooked and the time we left them the same, we only changed the type of heating.
The scientific explanation for this project was that when the sun heats the aluminum foil, the rays of the aluminum foil will bounce back into the plastic foil and it will heat up the food.
First, we clean any stray bits of cheese, sauce, or crumbs out of the pizza box. Using a ruler and pencil, we draw a square one inch in from the edges of the top of the box. We used a knife to cut out three of the four sides of the square. We made a crease along the cut side of the square to create a flap that stands up. We cut a piece of aluminum foil large enough to cover the inner side of the cardboard flap. We wrapped the foil tightly and secured it with tape. We lined the bottom of the pizza box with black construction paper. We cut two pieces of plastic wrap that are the same size as the top of the pizza box. We use tape to secure the plastic wrap to the inside edges of the square window you cut into the box. We rolled up some newspaper pages into tubes to stuff into the sides of the box. We make sure you are still able to close the lid of the pizza box. Now it was time to cook something! We used our oven at 3 PM. We made s’mores, nachos and hot chocolate.
For our project we needed: Cardboard pizza box, a pencil, ruler, scissors, aluminum foil, clear tape, black construction paper, transparent plastic bag, newspapers, oven mitt, and a pie plate.
