Aubrey young solar oven

  1. 1. Designing a solar ovenBy:Aubrey YoungMonday, May 20, 13
  2. 2. Imagine for design #1For our materials we will use 1 unit of Cotten,1unit of rocks,1 unit of clothSome advantages of this Idea is that it is less ofan impact on the environmentSome disadvantages of this idea is it will takelonger to heat up, cloth and Cotten are notnatural, we can only use one unit eachMonday, May 20, 13
  3. 3. Imagine for design #2We used 1 unit of rocks,2 units of news paperSome advantage to this idea is use lessmaterial,less impact on environment,goodinsulator, and it heats fasterSome disadvantages is the news paper hasink,less heather,and it is more toxicMonday, May 20, 13

  10. 10. Create for design #1Our heat score is our solar oven maximumtemperature subtracted from the control oven:55-55=0Our time score is the number of minutes it took tocool down witch was 5 minutesOur total impact score was 2 pointsOur total score for the solar oven is 3 pointsMonday, May 20, 13
  11. 11. Improve for design #1The total score for our first dolor oven was 3 pointsThe parts of our solar oven that worked well were the rocksone Cotten because over time the rocks heat up and helpheat the box and the Cotten is spread so it keeps more heatThe cloth did not work as well cause it keep fallingWe are going to try to improve our score heat scoreWe will improve our heat score by removing the cloth andadding sand because it traps the heatMonday, May 20, 13

  19. 19. ReflectionOur improved design worked well because thematerials that we used trapped the heat really well.We know this because the temperature increased.The material we changed was sand. The sand was agood insulator because It kept the heat in the box.If we could improve again we would not changeanything because with the shredded stuff we havein there like the cotton takes up more space totrap in the heat.Monday, May 20, 13
