In this article an oceanographer discusses her development of an activity to help students explore polar-related questions more fully. "The Polar Insulation Investigation" builds on students' natural interest in "things polar" and introduces them to animal adaptations in a unique way. The aim of the exploration is to determine the role of animal coverings (e.g. blubber, fur, and feathers) and to see which is the best insulator. It also provides an opportunity to develop and practice skills for measuring temperature.
