Designing a solar oven by angel.g

  1. 1. DESIGNING A SOLAR OVENBy Angel GallegosMonday, May 20, 13
  2. 2. Imagine for design #1• Idea 1• Our materials are white foam flat.• We need 3 units of white foam flat.• The advantages of this idea is that when we put it on thesides we could cover the holes that the box has except thebox where the terminator goes so we can trap heat.• The disadvantages of this idea is we could get a higherimpact score.Monday, May 20, 13
  3. 3. Imagine for design #2• Idea 2• Our materials are felt flat and foam flat• We need 2 units for felt flat and 1 unit for foam flat• The advantages are the felt would hold more heat.• The disadvantages would be that the felt might not getthat much heat and get a higher impact score.Monday, May 20, 13

  10. 10. Create for design #1• Our heat score is our solar oven maximum temperaturesubtracted from the oven control: 40-55=-15• Our time score is the number of minutes it took to cooldown which was 6 minutes.• Our total impact score was 9 points.• Our total score for the solar oven was -18.Monday, May 20, 13
  11. 11. Improve for design #1• The total score for our first solar system oven was 18• The parts of our solar oven that worked well was the aluminumfoil because the aluminum reflected the heat to the box.• The part of the solar oven that did not work was the foambecause we thought the foam would hold the heat but the foamdid not hold heat.• We are going to try to improve our heat and impact score• We are going to improve impact and heat by using items thatare recycled and we could use items that observes heat.Monday, May 20, 13

  18. 18. Design #2 create• Our heat score is our solar oven maximum temperaturesubtracted from the control oven: 44-53=-9• Our time score is the number of minutes it took to coolwhich was 2 minutes.• Our impact score is 22 points.• Our new total score for the solar oven is -19.Monday, May 20, 13
  19. 19. Reflection• Our improved design did not work well because in our first score we got-18 and in our second score we got -19 and we thought our new materialswould make a better insulator than our other materials.• The materials we changed where white foam to black foam and we addedaluminum.• Our materials worked poorly because when we put our aluminum we put iton each of the sides, and we just spread out the black foam all around theside of the felt and with the felt we just put all around the floor of the box.So I think that when it spread out the black foam did not get much sunlightbecause when we spread it out around the felt not much sun light could getto the black foam.• If could improve again we would shred our materials, because when we putmaterials in the cooler shred was a better insulator. We would also placeour aluminum where the light reflects to hold more heat in the black foam.We would also put our black foam where it would get more sunlight.Monday, May 20, 13
