  1. 1. Designing a Solar OvenBy Mackenzie MotaMonday, May 20, 13
  2. 2. Imagine for design # 1Idea # 1Our materials are cotton , newspaper and white cloth .We need 3 units .The advantage of this idea is they are not going to hurtthe environment and it will probably warm up a littlefaster .The disadvantages of this idea is it will burn to much .Monday, May 20, 13
  3. 3. Imagine for design # 1Idea # 2Our materials are cotton and foam.We need 3 units .The advantages of this idea its going to cook faster .The disadvantages of this idea is it will not help theenvironment .Monday, May 20, 13

  10. 10. Create for design # 1Our heat score is our solar oven maximum temperaturesubtracted from the control oven 60 ° c - 55 ° c = 5 ° cOur time score is the number of minutes it took to cooldown which was 3 minutes .Our total impact score was 6 points .Our total score for the solar oven is 2 points .Monday, May 20, 13
  11. 11. Improve for design # 1The total score for our first solar oven was 2 points .The parts of our solar oven design that did worked well were cottonand cloth because it helped it heat faster .The parts of our solar oven design that did not work well were thenewspaper because it did not helped to heat it faster .We are going to try to improve our heat , time and impact scores .We will improve our heat , time and impact score by using differentmaterials like dark cloth , foam and cotton because it will help get ahigh score .Monday, May 20, 13

  19. 19. ReflectionOur improved design did not work well because it did not havegood insulators . The materials we change were light cloth andnewspaper . The foam was a poor insulator because we did notplace the foam in the right place so it did not warm up quickly.In the data chart the highest score was 52.1 with our improveddesign, but we had the highest temperature of 60 with our firstdesign.If we would improve again we would change the materialsbecause the temperature did not go that high. To get a highertemperature, we would put our insulators directly in the sun toheat up.Monday, May 20, 13
