    • DEIGNING A SOLAR OVENBY MASON WOLFGRAMMMonday, May 20, 13
    • Imagine for Design # 1Idea #1•Our materials are white foam flat.• We need 3 units for white foam flat.•The disadvantage of this idea is we can get a higher impact score.•The advantages of using this idea are that when we put it on the sides we could cover the holesof the box except one hole where the thermometer goes.Monday, May 20, 13
    • Idea #2Our materials foam, and flat felt.We need 2 for felt 1 for foam.The advantage of the felt would be the felt could hold more heat.The disadvantage is that the felt would get a higher impact score.Monday, May 20, 13

    • Creating for design # 1• Our heat source is our solar oven we subtract the temp ofyour maximum temp• Our time score is the number of minutes it took to cooldown which took 6 min.• Our total impact score is 9.• Our total score for the solar oven is -18.Monday, May 20, 13
    • Improve for design # 1• The total sore for the our first solar oven was - 18 points.• The parts of our solar oven design that worked the mostwas aluminum foil, because the light reflects of the foiland cooks the food.• We are trying to improve our -18 score.Monday, May 20, 13

    • Create for design # 2• Our heat score is our solar oven maximum temperaturesubtracted from the control oven 37.6°c - 24.4°c = 13.2°c• Our time score is the number of minutes it took to cooldown which was -9• Our new total score for the solar ovens is -19Monday, May 20, 13
    • Reflection• Our improved design did not work because our score washorrible because we had a low heat score and a highimpact score.• We changed white foam to black, and then we addedaluminum. These were poor insulators because aluminumwas a reflector and conducts heat so it did not trap theheat.• If we could improve we would take off the foil and addshredded foam because it takes up more room to absorbthe heat.Monday, May 20, 13
