If I had the opportunity to build or change parts in my solar oven I would do the following:

• I would add more reflective materials because then the heat would be able to move around my solar oven to make my solar oven hotter
• I would seal the solar oven more so a lot less heat escapes through the holes
• I would make sure the pan is in the place where the sun reflects into my solar oven so your food would get hotter.
• I would make sure to add more material, like cardboard so the solar oven could consume more heat
• I would add more holes so more sunlight could get in the solar oven

Sincerely,
