Designing a solar oven By:Aubrey Young

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

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.
