Blubber Glove Experiment

In the Arctic Ocean, blue whales swim in very cold water.  They don't get cold because of their blubber, or fat.

Question: How long can we keep our hands in a bucket of ice water if we wear a blubber glove?

Hypothesis:

Zane predicts that he can keep his hand in ice water for 3 seconds without the blubber glove.  He predicts he can keep his hand in the ice water forever with the blubber glove.

Zoe predicts that she can keep her hand in the ice water for 10 seconds without the blubber glove.  She predicts that she can keep her hand in the ice water for 100 seconds with the blubber glove.

Procedure:

1.Fill a bucket with cold water and ice.
2.Fill a plastic bag with shortening (blubber).
3.Place one hand in the ice water and set a timer.  Take the hand out of the ice water when it gets too cold.
4.Place one hand in the plastic bag filled with shortening.  Set a timer and remove the hand when it gets too cold.

Results:

Zane kept his hand in the ice water for 6 seconds.  Zoe kept her hand in the ice water for 14 seconds.  With the blubber glove, Zane kept his hand in the ice water for 2 minutes and his hand did not get cold.  Zoe kept her hand in the ice water for 2 minutes and 25 seconds and her hand did not get cold.

Conclusion:

The blubber glove kept our hands warm even in the ice cold water.
