Rubber Blubber Gloves

In this experiment, learners work in pairs to create two gloves -- one that contains a layer of shortening (blubber) inside, and one that doesn't. By putting both glove-covered hands in a bucket of cold water, learners will find out if the blubber-covered hand feels warmer than the hand without the fat layer. Use this activity to explain how marine mammals live in extremely cold environments. Learners will also discover what it means to have a variable and a control during an experiment.
