Imagine for design #1For our materials we will use 1 unit of Cotten,1 unit of rocks,1 unit of cloth
Some advantages of this Idea is that it is less of an impact on the environment
Some disadvantages of this idea is it will take longer to heat up, cloth and Cotten are not natural, we can only use one unit each

Imagine for design #2
We used 1 unit of rocks,2 units of news paper
Some advantage to this idea is use less material,less impact on environment,good insulator, and it heats faster
Some disadvantages is the news paper has ink,less heather,and it is more toxic

Material UnitsWe will use material by
Rocks 1Placing it on
the bottom of solar oven.
Cloth 1Use to trap and instate
heat.
Cotten 1Use to instate
heat.

Create for design #1Our heat score is our solar oven maximum temperature subtracted from the control oven:55-55=0
Our time score is the number of minutes it took to cool down witch was 5 minutes
Our total impact score was 2 points
Our total score for the solar oven is 3 points

Improve for design #1The total score for our first dolor oven was 3 points
The parts of our solar oven that worked well were the rocks one Cotten because over time the rocks heat up and help heat the box and the Cotten is spread so it keeps more heat
The cloth did not work as well cause it keep falling
We are going to try to improve our score heat score
We will improve our heat score by removing the cloth and adding sand because it traps the heat

Plan for design #2Materials Units
How will we use the materials
Sand 1 Unit Place on bottom
Cotten 1 UnitSherd and put on edge of box
Rocks 1 UnitPlace on top of
sand

ReflectionOur improved design worked well because the materials that we used trapped the heat really well. We know this because the temperature increased. The material we changed was sand. The sand was a good insulator because It kept the heat in the box.
If we could improve again we would not change anything because with the shredded stuff we have in there like the cotton takes up more space to trap in the heat.
