  1. 1. Designing a solaroven By:Jaxon RMonday, May 20, 13
  2. 2. Imagine for design#1Idea #1What we imagined first was use white clothand white foamAll together we need 3 units or lessThe advantage for this idea is to use onlyinsulatorsThe disadvantage for this is that the foam isfar away from the least environmentalimpactMonday, May 20, 13
  3. 3. Imagine for design#2Idea #2Our materials are two units of newspaper ofone unit of pipe insulationOur advantage of this idea is that the pipeinsulation is thick and colored black whichattracts light from the sunOur disadvantage is of this idea is that thepipe insulation is second to last with hurtingthe environmentMonday, May 20, 13

  10. 10. Create for design#1Our heat score is our solar oven maximum temperaturesubtracted from the control oven: 73.4°c - 32.5°c = 42.9°cOur time score is the number of minutes it took to cooldown which was 4 minutesOur total impact score was 7 pointsOur total score for the solar oven is 15 pointsMonday, May 20, 13
  11. 11. Improve fordesign#1The total score for our first solaroven was 15 pointsThe parts of our solar oven designthat worked well were the insidebecause we were near the shadeWe will improve our heat score byusing better insulatesMonday, May 20, 13

  19. 19. ReflectionOur improved design did not work well becausethe sand did was not a good insulator. Thematerials we changed were cloth because wethought the sand would absorb the sunlight. Thematerial sand was a poor insulator because it didnot hold enough heat because our temperaturedecreased.If we could improve again, we would go back withour first design because they were good insulators.We could also place our shredded materialsdifferently so that the heat does not go out theholes.Monday, May 20, 13
