This study aimed to find out if an old shoebox and a thick tin foil can be converted to amore useful piece of cooking equipment .The feasibility of reflective solar heated grill that is built from a cardboard box, tin foil, and poster board as an alternative cooking equipment was studied in this research project. The cardboard box was cut and shape the tin foil is settled in the middle making it looks like a slide .we go outside in the heat of the sun. the barbeque sticks were placed in the spot where reflection of the sunlight focuses on the hotdog .just like a real skewer the hotdog were cooked therefore minutes tasted it and voila .real hotdogs on stick just like mom used to cook
A solar heated grill can be built from a cardboard box, tin foil, and poster board. Sunlight hits the reflective surface and focuses on the hot dog held in the center. Students can work in pairs or individually if there are enough materials .This is a parabolic cooker we built a while ago, so unfortunately we can't show step by step photos of it's construction. However, it's relatively easy to see how it was put together.It makes a great Physics project. Unlike most, you'll actually get some use out of it afterwards. Some of the principles it demonstrates are: 1. Optics: focusing parallel rays of incident light through the use of a parabolic mirror. 2. Energy transformation: light to heat
3. Renewable energy: solar power
General Objective: This study thru physics aims to find out if an old shoe carton box can be useful to make an alternative cooking machine.
SIGNIFICANCE OF THE STUDY
This study aims to find out if an old shoe carton box can be useful to make an alternative cooking machine.player is significant to different sectors for various reasons:· Serve as an eye-opener for those who don’t have a grill in their backyard who want to convert their old shoe box carton into a hotdog grilling machine.· Provide information to students and teachers with respect to the recycling of carton box or old shoe box ·
serve as motivating factor for the schools or institutions to direct their students and to Further strengthen their capabilities for developing old carton box into a cooking grill and other processes to maximize the recycling of old carton box .Furthermore, the outcome of the study will provide empirically ² based information to policy makers in Ecological recycled Waste Management. (RA 9003) junk cartons are usually stocked or thrown out elsewhere .Converting these non-functional cartons does not only support RA 9003 but it also opens an avenue to develop technology in the community.
1. Two pieces of heavy cardboard (like the side of a cardboard carton). The first piece must be at least ten inches square and the second smaller piece must be at least four inches by five inches. 2. A piece of light poster board eight inches wide and sixteen inches long. 3. Twelve-inch wide aluminum foil. (You will use about 32 inches of the material.) 4. Some masking tape. (You may experiment with other types of tape.) 5. Nine inch long sticks about 1/16 inch in diameter. You may also use lengths of heavy wire.
1. Select a long narrow box; the longer the box the more heat collection is possible.Choose a focal length between 5" and 10" and design a parabolic curve as seen in the picture. One template could be used for all the cookers. Trace the curve on the open end of the box so that it is centered and straight.
2.Cut out the curve with a utility knife. Stress the importance of being exact.Measure and cut a piece of posterboard...
