Cotton is a good insulating material
with the cotton insulator, the degree loss decreased by 3 degrees
Cotton is used to make blankets and sweaters so it should be a good insulation material
The hardest thing was to figure out the design of the insulator
A new skill I learned is how to use the electrical thermometer
We were trying to make the best insulator with the materials we have
We first came up with a design, then made a paper prototype, and finally we made our final product
One thing I am proud of is that 2 sixth graders actually managed to put together a working insulator
One limitation is the variety of materials is very limited
