Imagine design #1

Our materials are Cotten , 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 warm up a little faster .

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

Idea #1

Imagine for design # 1Idea # 2

The materials that we are going to use is foam and cotton .

We need 3 units .

The advantages of the idea it is going to cook food faster .

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

Plan for design Materials Units We will use the

materials for

Cotton 1We will put it on

one side the another .

White cloth 1We will put it on the other side of

the Cotton .

News paper 1 We will put it on the bottom .

Create design #1Out heat score is our solar oven maximum temperature subtracted from the control oven 60°c-55°c=5.

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

Our total impact was 6 points.

Our total score for the solar oven is 2 points

Improve for design #1

The score for our solar oven was 2 points .

The parts of our solar oven design that did not worked we'll 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 score.

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 time score is the number of minutes it took to cool down witch was 3 minutes

Our tool impact score was 11 points

Reflection Our improved design did not work because our first design's temperature went to 60°c and our improved design's temperature was 50°c.

The materials we changed were that we took out the cloth and the newspaper and the cloth was replaced by cotton and the newspaper was replaced by foam.

The materials were poor insulators because it did not warm up the oven that quickly which means the cotton was a poor insulator because it is thin.

If we were to improve we would take out the cotton because when we put more of it it did not heat up as fast or good like last time because cotton is thin and so that's why it did not heat of fast and good.
