Make blubber gloves

Learn about polar animals' adaptations with this experiment from the Nat Geo Kids book Try This! Extreme.

Extremely cold climates are full of life. What kind of adaptations do polar animals have to allow them to thrive in these environments? Learn about one survival tool with this experiment!

WHAT TO EXPECT

Some of the materials placed in the bag around the subject’s hand will prevent cold from reaching her hand better than others.

WHAT'S GOING ON

Fat—even a vegetable-based fat like shortening—insulates animals from cold. So the shortening provides a decent substitute for blubber, the layer of fat that seals, whales, walrus, polar bears, and other marine animals in polar climates have under their skin.

Other materials, such as foam, keep drinks warm because they don’t conduct heat, so the heat doesn’t escape through the sides and bottom of the cup.

By the way, the bucket full of icy water is similar to the temperature and texture of the water around ice floes—where animals like seals and whales tend to live.
