Solar Heated Grill
Acknowledgement
With sincere and deepest gratitude to many people who unselfishly extended their help,support and assistance to the ultimate realization of this investigatory project, theresearchers would like to acknowledge their heartfelt appreciation to:Mr. Tan, PHYSICS teacher who devoted his valuable time in reviewing andediting the manuscript and approving.giving suggestions and guidance whichsubstantially contributed in the preparation and completion of this investigatory project.MrsTaleno , class adviser for her moral support and encouragement to them during theresearch process. To all teachers for their support and kind consideration.Mr. & Mrs. Sumagang, Mr. & Mrs. Rojas, Mr. & Mrs. Casaul, Mr. Baa,Mrs. Grimaldo, andMr. Laureano their parents for moral support and providing them the financialassistance and deep concern all the way through their studies.IV-3, their classmates for prayers, moral support and encouragement which helpedthe researchers realized their dream.And above all, to God Almighty, for His bountiful spiritual guidance, blessings and loveThe Researchers

A solar heated grill can be built from a cardboard box, tin foil, and posterboard. Sunlighthits the reflective surface and focuses on the hot dog held in the center. Students canwork 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 bystep photos of it's construction. However, it's relatively easy to see how it was puttogether.It makes a great Physics project. Unlike most, you'll actually get some use out of itafterwards. 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 heat3. Renewable energy: solar power
