Science at Home - DIY Solar Cookers
There are two basic forms of solar cookers:
1. Box type
Pros: Good for cooking soups, beans, crisps and most things; can leave unattended for hours and things don't burn; can put things in the morning and come back in the afternoon and they are cooked and warm
Cons: Can't fry things and doesn't brown bread
2. Parabolic type:
Pros: Can fry things and cook things like scrambled eggs; cooks quickly, like a stovetop; temperatures get hotter
Cons: Need to attend the solar cooker; things can burn

Solar ovens are very versatile. They are great for cooking a number of things, and a benefit is that things don't burn. You can put beans out in the morning and when you get back from school they are cooked and warm and NOT burnt. Box solar ovens (as compared to parabolic) aren't good for things like frying things and don't brown bread. Besides, that they are awesome! Most recipes you use can be done in a solar oven. Sometimes there may be reduction to the amount of water needed.
