  • 1. DANIEL GONZALEZDesigning a Solar OvenMonday, May 20, 13
  • 2. Imagine for design number one• 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 disadvantage of this idea is that the foam has a biggerimpact to the environment.Monday, May 20, 13
  • 3. Imagine for design number two• Idea number 2• Our materials are shredded felt, flat foam.• We need two units shredded felt, and one unit of flatfoam.• The advantage of this idea is shredded materials are betterinsulators so there is more shredded then flat.• The disadvantage of this idea is we might not haveenough foam for the sides of the oven.Monday, May 20, 13

  • 9. Create for design #1• Our heat score is our solar oven maximum temperaturesubtracted from the control oven:62°C-55°C=7°C• Our time score is the number of minutes it took to cooldown which was 4minutes• Our total impact score was 11• Our total score for the solar oven was 0Monday, May 20, 13
  • 10. Improve for design number one• The total score for our first solar oven was 0points.• The parts of our solar oven design that worked well werethe shredded felt because the shredded materials are betterinsulator.• The parts of our solar oven that didnt work well was theflat foam because even though its good insulator it stilldidnt work wellMonday, May 20, 13

Creat for design #2• Our heat score is our solar oven maximum temperaturesubtracted from the control oven:54-53=1• Out time score is the number of minutes it took to cooldown which was 7minutes• Our total impact score was -4 points• Our new total score fore the solar oven is 14Monday, May 20, 13
  • 19. Reflection• Our improved design worked well because the last time wegot 0 and now we got 12. The materials we changed weregood insulators because our temperature increased. Ourmaterials we changed were rock, sand, and newspaper.• If we could improve again, we will put the rocks on thebottom and then we would put the newspaper on top ofthe rocks. Then, we would put the sand on top ofnewspaper because I think the sand keeps in the heatwhen it gets more solar energy.Monday, May 20, 13
