PHYSICS TO WIN IT:

HEAT IS ON

CHALLENGE

Page 3: Solar Oven Ideas

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)

Page 7: Solar Oven Ideas

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!

4/9/13 Tuesday: Final proposal of design, materials, and recipe (if cooking food)

4/15/13 Tuesday: ALL MATERIALS DUE (in class time to assemble solar oven)

4/16/13 Wednesday: COMPLETED SOLAR OVEN DUE HEAT IS ON CHALLENGE DAY: TBD because of

weather (hopefully 4/17/13 Thursday)
