Blubber!

Not only do we talk about the layer of blubber that penguins have, but we sure try to figure out what it is and how it works! Below is a picture of the blubber mitts that we used in an icy cold bucket of water.  Brrrr!

Here is a sample of what some of the children have to say:
"It's warm! You don't even feel the coldness."
"This hand is cold. This hand is warmer."
"The hand without the blubber mitt is cold. The hand with the blubber mitt doesn't make my hand cold."
"The blubber mitt makes that water not so freezing!"
"The blubber mitt is warmer. Blubber keeps the penguins warm."



Seems to me like they are getting the idea! Want to explore it at home? Place a ziploc bag inside of another one and add lard or shortening in between the two. Seal closed by using duct or masking tape at the top and you're ready to go.
