February 27th is International Polar Bear Day! What a wonderful time to discuss the Arctic, preservation and Arctic wildlife. Polar Bears are fascinating creatures.
Experiment with Blubber!
My children (and I) really enjoyed one experiment in particular – the Blubber Glove. In this experiment you use Crisco as “blubber” and test its insulation effect in ice water. At first I thought – Crisco – no way!! But I gave it a shot and it was awesome. You only need two storage bags, Crisco, duct tape and ice water! Now that is my kind of science project.
It was pretty quick to prep our Blubber Glove and the kids could not imagine what we were doing with it!! I love it when I can stump the kids. So, we discussed polar bears and how they live in such a COLD climate. We would never survive but the polar bears have a special layer of fat to help them endure the cold.
At first I was a little skeptical of how well it would work. Mara (pictured above) tried it first. Of course she is a very reasonable kid and easy to please so I immediately had to try it for myself. I was astounded at the difference a seemingly thin layer of Crisco made! Then imagine a thicker layer and no wonder polar bears are comfy. Definitely one of the most worthwhile experiments we have done.
