Third Grade Experiments With "Blubber Gloves"

Third Grade has been studying the Iditarod "Great Sled Race" in social studies.  As part of that, they are looking at how the animals in the Arctic have adapted to extremely cold temperatures.

The "Blubber Glove" - i.e. Crisco in between two Ziploc baggies, mimics blubber when they put their hands in ice water.  They all experienced that the "blubber glove" was warm, while the bare hand was cold!
