Imagine for design # 1Idea # 1

Our materials are cotton , newspaper and white cloth .

We need 3 units .

The advantage of this idea is they are not going to hurt the environment and it will probably warm up a little faster .

The disadvantages of this idea is it will burn to much .

Idea # 2

Our materials are cotton and foam.

We need 3 units .

The advantages of this idea it's going to cook faster .

The disadvantages of this idea is it will not help the environment .

Create for design # 1

Our heat score is our solar oven maximum temperature subtracted from the control oven 60 ° c - 55 ° c = 5 ° c

Our time score is the number of minutes it took to cool down which was 3 minutes .

Our total impact score was 6 points .

Our total score for the solar oven is 2 points .

Improve for design # 1The total score for our first solar oven was 2 points .

The parts of our solar oven design that did worked well were cotton and cloth because it helped it heat faster .

The parts of our solar oven design that did not work well were the newspaper because it did not helped to heat it faster .

We are going to try to improve our heat , time and impact scores .

We will improve our heat , time and impact score by using different materials like dark cloth , foam and cotton because it will help get a high score .

Our heat score is our solar oven maximum temperature subtracted from the control oven : 52 - 53 = -1 .

Our time score is the number of minutes it took to cool down which was 3 minutes .

Our total impact score was 11 points .

Our new total score for the solar oven is - 9 .

Reflection Our improved design did not work well because it did not have good insulators . The materials we change were light cloth and newspaper . The foam was a poor insulator because we did not place the foam in the right place so it did not warm up quickly. In the data chart the highest score was 52.1 with our improved design, but we had the highest temperature of 60 with our first design.

If we would improve again we would change the materials because the temperature did not go that high. To get a higher temperature, we would put our insulators directly in the sun to heat up.
