Mariana design a solar oven

  1. 1. Designing a Solar OvenBy; Mariana LopezMonday, May 20, 13
  2. 2. Imagine for Design #1Idea # 1Our materials are we used cotton for one side. We also usednewspaper for the bottom . And we also used light cloth to put iton one side.We need 3 units.The advantage of this idea is it will warm up a little bit faster. Andthey are not going to hurt the environment.The disadvantage of this idea is that it will probably burn to much.Monday, May 20, 13
  3. 3. Imagine for Design # 1Idea # 2Our material we are going to used foam in the bottom.And will used the cotton to the sides of the box.We need 3 units.The advantage of this idea its going to cook faster.The disadvantage of this idea it does not help theenvironment.Monday, May 20, 13

  11. 11. Improve for Design #1The total score for our first solar oven was 2.The parts of our solar oven design that work well were the cotton andthe cloth because helped a little to heat it up faster.The parts of our solar oven design that did not work well were thenewspaper because did not worked well for the project.We are going to try to improve our Heat Score Time Score Impact Score.We will improve our Heat Score Time ScoreImpact Score by usingdifferent materials like dark cloth , foam and cotton because it will helpget a high score.Monday, May 20, 13

  19. 19. ReflectionOur improve design did not work well because we didnt have agood insulator. The materials we changed were cloth & thenewspaper. The materials were poor insulator because the clothit was to light for the project and it didnt warm up so the clothneeded to be darker.If we could improve again, we would change the materialsbecause the materials were bad insulators or maybe because theruler felt a lot of times which closed our box.In the first design the highest temperature was 59.7°c and thesecond time with our improved design we got 52.1°c.Monday, May 20, 13
