  1. 1. Designing a solar ovenBy Trenton PrzybylskiMonday, May 20, 13
  2. 2. Imagine for design #1• Idea number one• Our materials are shredded felt, flat foam.• We need one unit of shredded felt, and two units of flatfelt.• The advantage of this idea is both materials are goodinsulators and will cover the inside of the solar oven.• The disadvantages of this idea is the foam has a biggerimpact to the environment.Monday, May 20, 13
  3. 3. Imagine for design #1• Idea two• Our materials are shredded felt, flat foam.• We need two units of shredded felt, and one unit of flatfoam.• The advantages of this idea is shredded materials arebetter insulators, so there is more shredded than flat.• The disadvantages of this idea is we might not haveenough foam for the sides of the oven.Monday, May 20, 13

  10. 10. Create for designNumber one• Our heat score is our solar ovens maximumtemperature subtracted from the control oven:62°C-55°C=7°C.• Our time score is the number of minutes it tookto cool down which was 4 minutes.• Our impact score was eleven points so thattells me I need to improve our score becauseour first two materials was processed.Monday, May 20, 13
  11. 11. Improve for designnumber one• Our score for the first solar oven as 0 points.• The parts of our solar oven design that worked wellwere the shredded felt because the shreddedmaterials are better insulators.• We are going to improve the impact score becauseour impact score is high and we want to bring itdown so we are going to improve it choosing theitems that are natural and not the items that areprocessed.Monday, May 20, 13

  18. 18. Create for designnumber two• Our heat score is our solar ovens maximumtemperature subtracted from the control oven:54 - 53 = 1.• Our time score is the number of minutes it tookto cool down which was 7 minutes.• Our total impact score was -4 points.• Our new total score for the solar oven is 12.Monday, May 20, 13
  19. 19. Reflection• Our improved design worked well because the first materials wehad made us get a really low score which was zero and thistime our score was 12 which was an improvement. Thematerials we changed were foam, and felt because they had anbigger impact on the environment. The sand, rocks andnewspaper were good insulators because they made ourtemperature increase and had a low impact on the environment.• If we could improve again we would have three materialsbecause that would make our score a lot higher and make ourimpact score lower. My group is a lot happier because wewould have a higher score than everybody who usednewspaper.Monday, May 20, 13
