Science for Students: What Makes a Good Insulator? Energy will always be transferred from the object with a higher temperature to one with a lower temperature In other words, heat will always flow from hot to cold When we try to insulate something, we are trying to keep the energy from being transferred from a hotter object to a colder one
In this experiment, we'll be testing different materials to find the best heat insulator Once you're done with the experiment, you'll understand why certain materials hold heat better than others
