  1. 1. Designing a solar ovenBy: Mateo VesceMonday, May 20, 13
  2. 2. Imagine Design #1• Idea #1• We are using shredded white cloth and putting it on the sidesof the box. We are also using shredded white foam and puttingit on the bottom of the box.• We are using 1 unit of white cloth and 2 units of white foam.• The advantages of this idea is that all of our materials areinsulators and they are all not colored. This means that theydidnt have to use ink.• The disadvantages of this idea is that the foam is a bit far awayfrom being a material that hurts the environment least.Monday, May 20, 13
  3. 3. Imagine Design #1• Idea #2• Our materials are shredded newspaper and putting it onthe bottom of the box. We are also using shredded pipeinsulation and putting it on the sides of the box.• We need 2 units of newspaper and 1 unit of pipe insulation.• The advantages of this idea is that the pipe insulation isthick and colored black which attracts light.• The disadvantages of this idea is that the pipe insulation issecond to last with hurting the environment.Monday, May 20, 13

  10. 10. Create Design#1• Our heat score is our solar oven maximumtemperature subtracted from the control oven:73.0 c - 55.0 c = 18.0 c• Our time score is the number of mins it took to cooldown which was 4 mins.• Our total impact score was 7 points.• Our total score for the solar oven is 15.Monday, May 20, 13
  11. 11. Improve Design #1• The total score for our first solar oven was 15 points.• The parts of our solar oven design that did not work well was thatsome of the shade from the tree was on our solar oven so nexttime we are staying as far away from shadows as possible.• The parts of our solar oven design that did work well was thematerial we used because they were very good insulators. Weknew this because our solar oven got up 73.4°c which was thehottest oven of the grade.• We are going to try to improve our heat score.• We will improve our heat score by getting no where near theshadows of trees.Monday, May 20, 13

  18. 18. Create Design #2• Our heat score is our solar oven maximum tempsubtracted from the control oven:39.0°c - 41.0 = -3.0• Our time score is the number of mins it took to cooldown which was 9 mins.• Our total impact score was 5 points.• Our new total score for the solar oven is 1.Monday, May 20, 13
  19. 19. Reflection• Our improved design did not work well because wechanged our white cloth to sand. We know this wasntimproved because our temp dropped 40° whenheating. Now we know that sand isnt a goodinsulator.• If we could improve our design again, we wouldchange our sand back to cloth because when we usedcloth in our first design, it insulated more than thesand. I know this because our temperature washigher when we used the cloth.Monday, May 20, 13
