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
