We did that simple experiment where you put Crisco in a plastic bag and let the children hold it with an ice cube on top, so they can see how it keeps your hand warm. We did that as a demonstration of the blubber many arctic animals have. As a follow-up activity, I asked the kids to write about what a new use for blubber could be, using their imaginations.
for a coat
for the animals and the homeless...so they won't get sick.
To play a cool prank on your mom. :)
