Abstract
The researchers thought of trying to come up with a makeshift solar cooker in order to test if this way of cooking may be effective and useful in substituting for a frying pan and a stove. The solar cooker may be a possible alternative when cooking outdoors under the heat of the sun. It could also be a huge energy saver and a safer way of cooking, avoiding hazards such as burns. The researchers have picked the safest and easiest procedure and materials in making a solar cooker so that teenagers or even people younger may try making it themselves. The first step in making the solar cooker was finding the right materials. This included a long narrow box, poster board, a roll of foil, Popsicle sticks, cardboard and barbecue sticks. Since the focal point needed to be somewhere in between 5” to 10”, one box was placed on top of another box of the same length and width. Popsicle sticks were taped to the insides of the box as support. The focal point was set and a piece of poster board, measured to fit in the middle of the box was placed there. The foil was then placed on top of the poster board, making sure it was not as furrowed as possible. It was placed in the heat of the sun and there was a certain spot where the light hit. Two pieces of cardboard were taped to the sides of the spot and the barbecue stick with a whole piece of hotdog was placed where the light hit. The solar cooker with the hotdog was left under the sun’s heat while the researchers watched if it would work. It took about 20-25 minutes before the hotdog was cooked. The researchers then tried to cut another piece of hotdog into smaller pieces to see if it would lessen the time being consumed. It took about 15-20 minutes in cooking the smaller pieces. Lesser time was
