Building a cardboard solar oven for science fair?

Question

I want to help my daughter build a solar oven for her science fair in a week...I'd like to use glass for the window instead of plastic. Any tips on building one that will really work? Which design would work the best to bake?

Thanks in advance!

Answer 1

first build a pyramid shape with cardboard, besure to glue in and smooth out foil or use plastic mirrors on the inside before.cut in half horizontally use the smaller piece as the top flip over bigger piece big side down.  build a frame that will hold all the parts. and it all depends on the suns position.for it to work well.

theirs diffrent was to make them but thats the one I made.

it would been better if I can remember the site for some perfect ones.

Answer 2

Check your local library for the books _Cooking with Sunshine_ by Lorraine Anderson and _Solar Cooking_ by Harriet Kofalk.  Very helpful books, with designs and recipes.
