  • 1. Making a solar oven by:TreyMonday, May 20, 13
  • 2. Imagine for design #1Idea #1Our material are white cloth and white foamWe need 3 unitsThe advantage of this idea is all of the materials areinsulators.The disadvantage of this idea is that the foam is a bitfar away from the least environmental impact.Monday, May 20, 13
  • 3. Imagine for design# 1idea #2Our materials are two units of newspaper and one unit ofpipe insulationWe need 3 unitsThe advantage of this idea is that the pipe insulation isthick and colored black which attracts lightOur disadvantage of this idea is that the pipe insulation issecond the last with hurting the environment.Monday, May 20, 13

  • 6. Plan for design #1White cloth 2 units = 2 sheet Shred itWhite foam 1 unit = 1 sheet Shred itMonday, May 20, 13
  • 7. ImproveThe total score for our first solar oven was 15 pointsThe parts of our solar oven design that worked wellwere were good insulators and we had a flat foil paperthat reflects good.The parts of our solar oven design that did not workwell were the inside because we were near the shade.We will Improve our heat score by using better insulates.Monday, May 20, 13

  • 18. Create for design #2Our heat score is our solar oven maximumtemperature subtracted from the control oven:37-53 = 16Our time score is the number of minutes it took tocool down which was 10 minutesOur total impact score was 5 pointsOur new total score for the solar oven is -11Monday, May 20, 13
  • 19. ReflectionOur improved design did not work well because thesand was not a good insulator because our temperaturedecreased . The materials we changed were cloth whichwas a good insulator because our temperatureincreased. We changed the cloth though because wethought the sand would heat up like at the beach.If we could improve again we would change it back tocloth and foam because they were better insulators.Monday, May 20, 13
