  1. DESIGNING A SOLAR OVENELI GOSSETTMonday, May 20, 13
  2. Imagine For Design # 1• Idea #1 Dark cloth for the bottomabsorbs heat good-1 sheet. Cotton ballsfor a low impact score-2 cups.• Our materials are dark cloth and cottonballs.• We need 1 unit of cloth and 2 units ofcotton balls.• Our advantage of this idea is that thecloth will absorb all the heat and be agood insulator.• Our disadvantages of this idea is that theother heat that the cloth doesnt absorbwill bounce of the cotton balls wontabsorb it and will bounce out.Monday, May 20, 13
  3. Imagine For Design #1• Idea #2 Light colored cloth forthe sides-1 unit. Colored shreddedfoam for good insulation-2 units.• Our materials are light colored clothand shredded colored foam.• We need 2 units of colored foam and1 unit of light cloth.• The advantage is that the light clothwill bounce of and the foam willabsorb it all.• The disadvantage is the foam wontabsorb all of it and let some of it out.Monday, May 20, 13

  10. Create For Design #2• Our heat score is our solar oven maximum temperaturesubtracted from the control oven 56°C-55°C= 1°C.• Our time score is the number of minutes it took to cooldown which was 4 minutes.• Our total impact score was 9 points.• Our total solar oven score is -4 points.Monday, May 20, 13
  11. Improve For Design #1• The total score for our solar oven is -4 points .• The parts of our solar oven design that work well were our darkcloth because it absorbed some heat.• The parts of our solar oven design that didnt work well were ourcotton balls because they didnt absorb any heat.• We are going to try to improve our heat score by getting dark foamand cloth.• We will improve our heat score by shredding the two sheets of foamfor more insulation, and light cloth because it will reflect the heatand make the foam absorb the heat.Monday, May 20, 13

  18. Create For Design #2• Our heat score is our solar oven maximum temperaturesubtracted from the control oven:40-41=-1.• Our time score was the number of minutes it took to cooldawn which was 4 minutes.• Our total impact score was 10 points. Our new total scorefor the solar oven is -7.Monday, May 20, 13
  19. Reflection• Our improved design didnt work because the black andgreen foam wasnt able to insulate the heat very well andmost the heat got out. We know this because ourtemperature dropped quickly when cooling in the shade.• If we could improve again, we would get some newspaperand put it on the sides and a little on the bottom (2 sheets).We would get 1sheet of felt for the rest of the bottom.Well get rid of the black foam and green foam becausethey were a poor insulation because we did not put themin the right spots in our solar oven.Monday, May 20, 13
