  2. 2. Imagine for Design #1Idea #1Our materials are cloth ( to line the insideperimeter of the solar oven)rocks ( to puton the bottom of the solar oven), andCotten ( to put in the side holes)We need one unit for each material.The advantages to this idea is that it will notimpact the environment a lot, the food willbe heather, and the materials are all goodinsulators.The disadvantages are that we can only useone unit each, cloth and Cotten are notnatural, and it will take longer to heat up.Monday, May 20, 13
  3. 3. Imagine for Design # 2Idea #2Our materials are rocks ( to line thebottom of the solar oven) and newspaper( to fill the side holes and line the edge ofthe solar oven).We will need 1 unit for the rocks and 2 unitsfor the newspaper.The advantages for this idea are that ituses less materials are used, the materialsare good insulators, and will heat morequickly.The disadvantages are that the newspaperhas ink so it would be less heather.Monday, May 20, 13

  12. 12. Improve for design #1The total score for our first solar ovenwas 3 points.The parts in our solar oven that workedwell were rocks and Cotten becauseover time the rocks were hot and theyhelped heat the solar oven and theCotten can spread out easily so it cantrap more heat.The parts that did not work well werecloth because the cloth was in littlepieces around the box instead of layers.We are going to try to improve our heatscoreWe will improve our heat score byadding more rocks because when therocks heat up they help heat the box ifwe add more it might heat up morequickly.Monday, May 20, 13

  19. 19. ReflectionOur improved solar oven did better than the original because boththe sand and the rocks helped to heat the box.The Materials that worked are sand and rocks because the sandand rocks keep heat inside themselves so they heat the box too.The material that did not work as well is the cotton because thecotton was at the bottom of the box but, maybe if we put it higheron the box it might work better.If we were to improve the solar oven agin we would keep the sandand rocks because they are good insulators and add 1 more unit tothe rocks and put the other unit of rocks on the walls.Monday, May 20, 13
