This document describes a math project to build a solar hot dog cooker using the principle of a parabola. A group of three students constructed a parabola with a known equation of y=0.035x^2 and focus of 7.14 cm. They traced the parabola onto a shoebox, covered it with aluminum foil, and placed a hot dog at the focus point to be cooked by sunlight reflected by the parabolic shape. A parabola is used because its shape focuses parallel sunlight rays to a single point, allowing the concentrated solar energy to cook the hot dog placed at the focus.

AIM OF PROJECT USING SOLAR ENERGY BAKING OF A HOT DOG we do this with the help of of parallel lines and focus of parabola
PROCEDURE 1.Using graph paper,contruct a parabola of known eqn(y-k)=4ax^2. 2. Known eqn is needed to calculate exact focus
OUR PARABOLA EQUATION Y=0.035X^2 FOCUS=7.14 cm

WORKING OF PROJECT 3.Trace the parabola on shoe box with help of scissor ,etc 4.Paste the aluminium foil on poster box and fix it on surface of parabola
WHY PARABOLA??
The parabola is shaped so that it collects the sun rays and focuses them at one point, the focus, in the center of the parabola. This is where the hot dog is placed, and the energy from the sun is used to cook the hot dog. Because the sun is so far away from the earth, the light rays hitting us are essentially parallel. Parallel incident rays of light which strike a parabolic mirror all pass through the same point after they are reflected. Light is reflected off of nearly everything, but we used foil because its highly reflective and much of the heat and energy from the incoming sun rays is redirected to the hot dog. This would not work with a material that was not reflective.
