Physics To Win It: Heat Is on challenge Solar Oven Ideas
Why Solar Ovens • Go Green • http://www.youtube.com/watch?v=KIap7v3NHZ4 • Nature Conservancy: Haiti • http://www.youtube.com/watch?v=shqgNSC1O3M • Pizza Box • http://www.youtube.com/watch?v=xbwliZJiHe8
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!
Calendar of Events • 4/2/13 Tuesday: Create Teams, Team Name, Brainstorm Ideas, preliminary list of materials • 4/8/13 Monday: GUARDIAN SIGNATURE is REQUIRED. In class time to research design and materials wanted • 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)
Rough Draft Proposal • Team Name: • Team Members: • Possible Materials, quanities and Rational/Explanation FOR ALL MATERIALS DESIRED: • Design Sketch and LABELED!
Grading Requirements For Each Group • Final Proposal (requirements coming) 20pts. • Solar Oven, materials must be approved before hand (rough draft proposal) 20pts. • (temperature must be raised to at least 100 degrees F ) • Calculations 10pts.
Final Proposal • Team Name: • Team Members: • Hypothesis: estimated final temperature _______ • Possible Materials, quanities and Rational/Explanation FOR ALL MATERIALS DESIRED: • Design Sketch and LABELED!
