Designing a Solar OvenBy: Diana AlvarezMonday, May 20, 13
Imagine for design #1Idea #1Our materials are cotton to put it on the side, we will use newspaper for the bottom, and we will also use with cloth to put it onthe other side.We need 1 unit for cloth, 1 unit for news paper and 1 unit for cottonThe advantage of this idea is that it will warm up a little bit fasterwith does materials. The materials we use are not going to hurt theenvironment.The disadvantage was that it will probably not heat to much.Monday, May 20, 13
Imagine for design #1Idea #2Our materials are foam to put them on the bottom and wewill also put and we will use cotton to put them on both sidesWe need 1 unit of foam and we also need 2 units of cottonThe advantage is that it is going the heat up faster because ofthe materials we haveThe disadvantage is that the materials we are going to sue willhurt more the environment then the other materials.Monday, May 20, 13

Create for design #1Our heat score is our solar oven maximum temperaturesubtracted from the control oven: 60° c - 55= 5Our time score is the number of minutes it took to cooldown which was 3 minutes.Our total score was 6 pointsOur total score for the solar oven is 2Monday, May 20, 13
Improve for design #1The total score for our ﬁrst solar oven was 2 pointsThe 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 thenews paper because it did not helped to heat it fasterWe are going to try to improve our heat, time and impact in scoreWe will improve our heat, time and impact score by using diﬀerentmaterials like dark cloth, foam and cotton because it will help gat ahigh scoreMonday, May 20, 13
Create for design #2Our heat score is our solar oven maximum temperaturesubtracted from the control oven: Heat score 52-53= -1Our time score is the number of minutes it took to cooldown which was Time score= 3 minutesOur total impact score was 11Our new total. Score for the solar oven is -1 + 3= -9Monday, May 20, 13
ReﬂectionOur improve design did not work well because the materials weused didnt keep that much the heat inside.The materials we changed were news paper and cloth and the newspaper was replaced by foam and cloth was replaced by cottonThe materials were bad insulators because the foam did not helpheat up the solar oven and the cotton also did not help worm up thesolar oven, the materials did not help keep the heat inside the solarovenIf we would improve again we would change the materials because Idont think the material are good insulators.Monday, May 20, 13
