This activity shows students how certain animals stay warm in the winter by providing a life-like representation of the effects blubber. A zip-lock baggy containing Crisco is placed into a bucket of ice water. Students then place their hand into the baggy and note the temperature. I chose this activity because it provides an actual representation of how animals stay warm in the winter that students would likely remember in the future. If the lesson is properly constructed, this activity also encourages critical thinking, making predictions, and discussing observations. When using this activity in my classroom, I would first discuss various polar animals with my students, making sure to ask them their opinion on how the animals manage to stay warm. This would then lead to a discussion on how humans stay warm. After creating a list of various ways in which humans adapt to cold weather, I would conduct the "blubber" activity. I would then explain to students that polar animals have an extra layer of fat, called blubber, to keep them warm. As a class, we would then discuss how certain human adaptations mimic the polar animals' survival techniques.

I have used this activity many times along with adaptations for survival. Very clear and concrete experience for students.
