Pretend a grizzly bear and a rattlesnake meet in the desert. Look at the facts. Then you pick.

Would they meet?

Almost never. Their homes sit next to each other.

This is pretend and based on facts. Real animals usually hide or leave.

Read the facts. Make your card. The page waits to pick.

THE SCIENCE PICK

Grizzly Bear!

A STOMP

You skipped a final pick. The facts still stamp a champ.

On the desert, Grizzly Bear wins. Grizzly Bear is a lot heavier. Rattlesnake would still win some meetings at home.

In the wild, most animals skip a fight. We still judge who the bodies and the place would favor.

Science card: Grizzly Bear 6 · Rattlesnake 1 · ties 1.

Your card: Grizzly Bear 0 · Rattlesnake 0.

The last page follows the whole animal — body plus home — not one bar chart.
