Division 8 learned that polar bears have unique structural features that enable it to live in its frigid environment. Polar bears have:
- an outer layer of fur called “guard hair” which are thin clear tubes filled with air. Guard hair is waterproof.
- a layer of dense fur called “under fur”
- black skin that absorbs heat from the sun
- a 4-6 inch layer of blubber under the skin
We did some experiments to see how these features work. Ask me what we did.
