Your Mission

To design a solar oven that will create the most thermal energy in 45 minutes using common supplies (cardboard boxes (shoe box, pizza box, larger box, etc.) tin foil, plastic wrap, newspaper, etc.)

You must work in groups of 3 or 2 (need team name)

You will calculate volume of oven (minimum of 1,000cm3, joules of energy converted, and power of oven

You can choose to bring ingredients from the provided recipes (only) to make something for your group/self

Provided Items

Tin foil (about 4 sheets (8.5x11))Plastic wrap (about 4 sheets of

8.5x11)2 sheets black paper (which I

would like back at the end)Glue, staples, tape (not very

strong)

Items Your Team Must Provide

The container (be creative!)

Extra tin foil (if needed)

Extra plastic wrap (if needed)

Insulation (if needed)

Substitutes for any of the above materials (for example: if you want plexi-glass or something more heavy duty then plastic wrap)

Any pre-cooked food items (basically we are only melting or re-heating foods for safety reasons, must come packaged)

WARNINGS:

Please use caution when cutting cardboard, especially with sharp scissors or exacto knives

Please only bring food that is pre-cooked and packaged

DO NOT LOOK DIRECTLY AT THE SUN!
