Cooking in the Oven

So we made our ovens, tried to cook an egg in it, but they egg ended up just drying out.

We then decided to put chocolate in the oven to see how long it would take to melt. The two chocolates we chose to use were Hershey's kiss and Reese's peanut butter cup mini.

The egg was put in the oven at 6:40 AM. Then at 10:00 AM it started to get hard. At 11:22 AM the egg was drying up. Then, at 12:15 PM all the egg whites were dried up and all that was left was the yolk, hard.

The Hershey and the Reese’s peanut butter cup were put in around 11:30 AM, then at 11:55 AM the Reese’s was half melted, and so was the Hershey’s. Then at 2:30 PM, both the Reese’s and the Hershey’s were melted, but the peanut butter of the Reese’s was still there.

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 .
