Method.
To Create Solar Ovens:
1. Completely cover the larger box with Aluminum foil and seal it with tape.
2. Line the inside of the smaller box with aluminum foil and secure it with tape.
3. Cut you construction paper so it fits comfortably inside the smaller box and secure it with tape.
4. Place a generous amount of shredded paper inside the larger box such that when you rest the smaller box on it, the opening is slightly below the opening of the larger box.
5. Centre the smaller box and fill remaining space with shredded paper.
6. Place the piece of chocolate onto some baking paper and place it inside the smaller box.
7. Place the piece of glass on the smaller box so that it is completely covered.
8. Take the oven outside into an area where a large amount of sunlight falls upon and position it so that the suns falls directly on it.
9. Find out what part of the oven absorbs the heat - with this, create 2 other solar ovens (different designs) which you are to test with some chocolate.
10.Take all 3 ovens outside in an areas where a lot of sunlight is produced. Position them all so that the sun falls directly on it.
11.Measure the temperature of the chocolate every 5 minutes; you should notice that it is slowly increasing.
12.Wait and observe which piece of chocolate melts the fastest.
13. Take the glass piece off and place it aside to cool down.
14. Note down which design was the most effective :)

Variables.
Independent Variables: Design of the Solar Oven
Dependent Variables: Temperature of the chocolate, Time it takes for the oven to warm up
Control Variables: The Chocolate, The Day and Time.
