Imagine for design #1Idea #1

Our materials are cotton to put it on the side, we will use news paper for the bottom, and we will also use with cloth to put it on the other side.

We need 1 unit for cloth, 1 unit for news paper and 1 unit for cotton

The advantage of this idea is that it will warm up a little bit faster with does materials. The materials we use are not going to hurt the environment.

The disadvantage was that it will probably not heat to much.

Imagine for design #1Idea #2

Our materials are foam to put them on the bottom and we will also put and we will use cotton to put them on both sides

We need 1 unit of foam and we also need 2 units of cotton

The advantage is that it is going the heat up faster because of the materials we have

The disadvantage is that the materials we are going to sue will hurt more the environment then the other materials.

Create for design #1

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

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

Our total score was 6 points

Our total score for the solar oven is 2

Improve for design #1

The 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 news paper because it did not helped to heat it faster

We are going to try to improve our heat, time and impact in score

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

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

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

Our total impact score was 11

Our new total. Score for the solar oven is -1 + 3= -9

Reflection Our improve design did not work well because the materials we used didn't keep that much the heat inside.

The materials we changed were news paper and cloth and the news paper was replaced by foam and cloth was replaced by cotton

The materials were bad insulators because the foam did not help heat up the solar oven and the cotton also did not help worm up the solar oven, the materials did not help keep the heat inside the solar oven

If we would improve again we would change the materials because I don't think the material are good insulators.
