Hairy, Fat and Warm
Grade Level: 6th; Type: Zoology
The goal of this experiment is to demonstrate the way that external and internal physical characteristics contribute to an animal’s warmth. Animals with thick coats of fur and/or feathers and animals with a layer of blubber beneath their skin can tolerate extreme cold conditions. Both the external coat and the insulating fat trap warm air near the body, refusing to let the heat escape.
