  1. 1. Designing a solar ovenBy: DiegoMonday, May 20, 13
  2. 2. Imagine for design #1• Idea #1• Our materials are shredded white clothand putting it on the side of the Box. Weare also using shredded white foam andwe are putting it on the bottom of the box.• We need 1 unit of white cloth and 2 unitsof white foam.• The advantage of this idea is that all ofour materials are insulators and are notcolored.• The disadvantage of this idea is that theis a bit far away from the leastenvironmental impact.Monday, May 20, 13
  3. 3. Imagine for design #1• Idea #2• Our materials are shredded newspaperand we will put it on the bottom of the box.Our other material is shredded pipeinsulation and we will be putting it on theside of the box.• We have 2 units for shredded newspaperand 1 unit for shredded pipe insulation.• The advantage of this idea is that the pipeinsulation is thick and colored black whichabsorbs heat.• The disadvantage of this idea is that thepipe insulation is second to last withhurting the environment.Monday, May 20, 13

  10. 10. Create for design #1• Our heat score is our solar oven maximumtemperature subtracted from the control oven:73.0°c - 55.0°c = 18.0°c.• Our time score is the number of minutes it tookto cool down which was 4 minutes.• Our total impact score was 7 points.• Our total score for the solar oven is 15 points.Monday, May 20, 13
  11. 11. Improve for design #1• The total score for our first solar oven was 15 points.• The parts of our solar oven design that worked wellwere flat foil because it reflected the light good.• The parts of our solar oven design that did not workwell was the inside because we were near the shade.• We are going to try to improve our heat score.• We will improve our heat score by using betterinsulators because it will help keep the box warmer.Monday, May 20, 13

  18. 18. Create for design #2• Our heat score is our solar oven maximumtemperature subtracted from the control oven:39.0°c-41.0°c=-3.0°c• Our time score is the number of minutes it tookto cool down which was 9 minutes.• Our total impact score was 5 points.• Our new total score for the solar oven is 1.Monday, May 20, 13
  19. 19. Reflection• Our improved design did not work wellbecause we changed our cloth with sandwhich wasnt a good insulator. We could tell itwasnt a good insulator because thetemperature dropped about 40°C whenheating.• If we could improve again, we would use betterinsulators like foam pipes because it wouldkeep the heat in.Monday, May 20, 13
