A 60 minute lesson in which students will investigate how blubber works as an insulator.
Prior to conducting the lesson, review the procedure and equipment required for the experiment.
Latex or rubber gloves
Vegetable fat (such as copha)
Watch the Animals of the Ice: Emperor Penguin video on YouTube. Discuss how many animals living in the coldest environments on Earth (such as Antarctica) have a thick layer of blubber to protect them from the freezing temperatures.
Explain to the students that they will be working in small groups to investigate whether or not blubber is an effective insulator (that is, can trap heat).
