Did you know that blubber has three functions? It acts as a source of energy, buoyancy, and insulation. Take a peek into Mr. Stone's classroom as they explore how blubber helps marine mammals survive the icy waters of the arctic. This was a very appropriate activity for today, since our own temperature in Virginia has hit a record low. I hope we don't adapt to the cold by developing a layer of blubber!
