Shakiyah solar oven

  1. 1. Designing a solar ovenBy:"akiyah f#seBy:"akiyah f#seMonday, May 20, 13
  2. 2. Imagine for design #1Idea#1Our materials are flat felt and shredded clothWe need 2 units of felt and 1 unit of clothThe advantages of this idea is that felt is goodinsulation.The disadvantages of this idea is a disadvantageis getting a high score on environmental impact.Monday, May 20, 13
  3. 3. Imagine for design #1Idea #2Our materials are shredded foam and flat feltWe need 1 unit of foam and 2 units of feltThe advantages of this idea is an advantage of ouridea is that we will have better insulation that we hadfor the 1st ideaThe disadvantages of this idea isa disadvantage is thatfoam has a high amount of environmental impactMonday, May 20, 13

  10. 10. Create for design #1Our heat score for our solar oven maximumtemperature subtracted from the control oven.56°c -55°c = 1Our time score is the number of minutes ittook to cool down which was 4 minutesOur total score was 9 pointsOur total score for the solar oven is -4Monday, May 20, 13
  11. 11. Improve design #1The total score for our for our first solar oven wasThe parts of our solar oven that worked well were ourtime score worked the best because it took a long time tocool down.The parts of our solar oven that didnt work all were wedidnt have insulators that worked well.We were going to improve our heat scoreWe will improve our heat score by putting betterinsulation.Monday, May 20, 13

  19. 19. ReflectionOur improved design did not work because wehad a poor insulation.The poor insulation was thefoam, it did not keep the heat trapped in the box.If we could improve again ,we would use the 2units of foam for the sides and , 1 unit of cloth forthe bottom.We would use this because they areboth good insulators.Monday, May 20, 13
