Procedure:
our team will design a renewable composite insulation material.
Design Constraints:
· Composite insulation material must produce minimum heat loss, representing good insulating value.
· Composite insulation material must have overall uniform thickness less than or equal to one inch.
· Composite insulation material must have consistent internal composition.
· Individual insulation material(s) must be environmentally friendly.
· Individual insulation material(s) must be recyclable.
· Individual insulation material(s) must be economical.
· Composite insulation material dimensions must not exceed the overall dimensions of heat box apparatus top.
· The change in temperature inside the box is directly related to the heat absorbed or released by the air in the box.
· Composite insulation material must have overall uniform thickness less than or equal to one inch.

This is what we brainstorm the insulation would look like. we thought that the materials might be a bit weird but we just wanted to experiment with different types of materials.
The Insulation:

This is the material we came up with.It's made from aluminum, cardboard, rice and to seal it we used duck tape. It's about one inch thick and we think it will be a good insulator because it contains aluminum which is use from microwaves to coffer mugs. Were not using the same amount but we know it will keep heat in which is our purpose. We put in the cardboard and rice to experiment and see if they are good insulators.
Our Data:

This are the measurements of the box. The box contains the heat source which is a 20watts light bulb. The insulation is on top of the box so it can trap the heat. As we know heat rises so we don't need to worry about covering the sides.

This is the data we got from the program we used to calculate the temperature.
Tin1= The temperature outside
Tmax1= Maximum temperature inside.
T Final= Final temperature inside
Tin= The temperature outside
T max= the max temperature outside.
T Final= the final temperature outside
t1= The time to cool up and to cool down.

Tmax1= Maximum temperature inside.

t1= The time to cool up and to cool down.
Conclusion
A good insulation has to trap heat in. The material must be able to keep heat in for a good number of minutes or hours. Our insulation beginning temperature was 52.25. After a 1,200 seconds or 20 minute it cool down to 44.5. That means that it went 8 degrees lower. I sadly think that its not a good insulator. 8 degrees is a lot of temperature drop. I wouldn't want my pizza to be 8 degrees cooler than when they first made it. If i were to do this again i would just put in materials that trap heat in and recyclable like plastic bags. The best recyclable insulation would be cotton balls and bags because they trap heat. Or material couldn't trap heat mainly because the material were bad.

We thought of all the things that we didn't have on the other insulation and came up with this one. We still have the aluminum which we thought was a big factor of insulation , and we added new things like cotton ball and a plastic bag. Our hypothesis is that this insulation will work better because it has more materials that we know are good insulation from past experience.

This was our data that we collected in our second insulation test. we think that this insulation we don't know yet why but or hypothesis it that it wasent closed.
