Designing a solar oven natalie vasquez

  1. 1. Designing A Solar OvenBy Natalie VasquezMonday, May 20, 13
  2. 2. Imagine design #1Our materials are Cotten , newspaper and white cloth .We need 3 units .The advantage of this idea is they are not going to hurtthe environment and it will warm up a little faster .The disadvantage of this idea is it will burn to much .Idea #1Monday, May 20, 13
  3. 3. Imagine for design # 1Idea # 2The materials that we are going to use is foam andcotton .We need 3 units .The advantages of the idea it is going to cook food faster .The disadvantages of this idea is it will not help theenvironment .Monday, May 20, 13

  10. 10. Create design #1Out heat score is our solar oven maximum temperaturesubtracted from the control oven 60°c-55°c=5.Our time score is the number of minutes it took to cooldown witch was 3 minuets.Our total impact was 6 points.Our total score for the solar oven is 2 pointsMonday, May 20, 13
  11. 11. Improve for design #1The score for our solar oven was 2 points .The parts of our solar oven design that did not worked well werecotton and cloth because it helped it heat faster.The parts of our solar oven design that did not work well were thenews paper because it did not helped to heat it faster.We are going to try to improve our heat ,time and impact score.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

  18. 18. Creating for design #2Our heat score is our solar oven maximum temperaturesubtracted from the control oven 52-53=-1Our time score is the number of minutes it took tocool down witch was 3 minutesOur tool impact score was 11 pointsOut new impact score for the solar oven is -9Monday, May 20, 13
  19. 19. ReflectionOur improved design did not work because our first designstemperature went to 60°c and our improved designs temperature was50°c.The materials we changed were that we took out the cloth and thenewspaper and the cloth was replaced by cotton and the newspaperwas replaced by foam.The materials were poor insulators because it did not warm up theoven that quickly which means the cotton was a poor insulatorbecause it is thin.If we were to improve we would take out the cotton because when weput more of it it did not heat up as fast or good like last time becausecotton is thin and so thats why it did not heat of fast and good.Monday, May 20, 13
