  2. 2. Imagine for design #1Idea #1We are using shredded white cloth andputting it on the on sides andshredded foam on the bottomWe have 1 unit of cloth and two unitsof foamThe advantages to this are foam is aMonday, May 20, 13
  3. 3. Imagine for design #1Idea #2We are using shredded newspaperon the bottom and shredded pipeinstallation on the sides.We need 2 units of newspaperand 1 unit of pipe installationThe advantages of this idea isthat the pipe installation is thickand black witch absorbs heatThe disadvantages of this ideais that the pipe installation is aharmful to the environment.Monday, May 20, 13

  11. 11. Improve fordesign#1The total score for our 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 notwork well was the inside because we were near theshade.We are going to try to improve our heat score.We will improve our heat score by using betterinsulators.Monday, May 20, 13

  19. 19. ReflectionOur improved design did not work becausethe sand was not a good insulator. When wehad cloth, it held in the heat but the sand didnot trap much heat inside the oven. We knowthis because our highest score with sand was39.1°C and our highest with cloth is 73.5°C.If we were to improve our design again Iwould take the sand out and put the clothback in because it held in a lot of heat.Monday, May 20, 13
