Making the Ovens

Materials:

• Medium sized-box with lid
• Smaller box to fit into the medium box
• 75 square feet of aluminum foil
  
• Newspaper
• Scissors
• Plastic wrap
• Stapler
• Black construction paper

After we got all of our materials, we began to assemble our solar oven. First we put the smaller box into the medium sized-box to make sure there was a 2-3 inch gap between the two. We then lined the medium sized-box with crumpled newspaper. Then, we placed the smaller box into the medium sized-box and filled the gap between them with more crumpled newspaper. We then lined the smaller boxes sides with aluminum foil and lined the bottom with black construction paper. Then we took a piece of cardboard about the size of the medium box to make reflectors and covered them with aluminum foil. The reflectors were then stapled to the outside of the medium box .
