Cortni fluker solar oven

  1. 1. Designing a solar ovenBy cortni flukerMonday, May 20, 13
  2. 2. Imagine for design #1page 1• Our materials are sand,Cotten balls and foam.• We need 1 unit of sand,1 unit of foam,and 1 unit ofCotten balls.• The advantage of this idea is that the sunlight will goto the sand on the bottom of the box and heat up thesand and the sand will heat the box up.• The disadvantage of this idea is that if the materialsover heat then the materials will burn.Monday, May 20, 13
  3. 3. Imagine design #1page 2• Are materials are sand,andfoil.• We need 2 units for foil,and 1unit for sand.• The advantage of this idea isthat the sand,and the foil willheat up the box,and we willget a higher score.• The disadvantage is that thefoil will burn up and not workany more,or burn the box.Monday, May 20, 13

  10. 10. Create• 56.0°c - 55.0°c=1.0°c soour heat score is 1.0°c• It took our solar oven 4minutes so our time score is4 minutes• Our total impact score is 4points.• Our total score for the solaroven is 1 point.Monday, May 20, 13
  11. 11. Improve• The total score for are first solar oven was1 point.• The parts of our solar oven design thatdid not work well where the foam did notwork as well as,and the cotton balls didnot work well either because the lightdidnt really attract to those materials.• The parts of our solar oven design thatdid work well where the sand because thesun heated up the sand and that heatedup the box.• We are going to try to improve our heatscore .• We are going to improve the heat scoreby putting aluminum around the sides ofthe box.Monday, May 20, 13

  18. 18. Creat for design #2• Our heat score is our solar oven maximumtemperature subtract from the control oven99-53=46• Our time score is the number of minutes it took tocool down witch was 10 minutes• Our total impact score was 5 points• Our total score for the solar oven is 46+10-5=51so our total is 51Monday, May 20, 13
  19. 19. Reflection• Our improved design worked well cause ourtemperature went up and thats good that means thatwe got better insulators. Our materials we changedwere we took out the foam and added aluminum foiland took out the cotton balls. The materials workedwell because we got a higher score then we did thefirst time.• If we could improve again we would put shredded feltin the box because it would make the box hotter.Shredded materials makes the box hotter because ittakes up more space.Monday, May 20, 13
