hi! so I have to make an experiment on heat loss & insulation and so, I did an experiment on which material insulates best against the wind of a fan--styrofoam, plastic or aluminum can. each has hot water in it but the styrofoam took the longest for the hot water to cool because its the best insulator.
how does this model a penguin's way of insulating? is there any connection with what makes styrofoam a good insulator and a penguin's feather? PLS HELP
