Rattlesnake

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

Would they meet?

No. Wild otters and rattlesnakes would not meet. We still look at the facts.

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

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

Otter can go 30 km/h. That is not very fast.

Rattlesnake

Rattlesnake can go 8 km/h. That is slow.

A fast animal can miss. A slow one only has to connect.

THE SCIENCE PICK

Otter!

A SQUEAKER

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

On the desert, Otter wins. Otter 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: Otter 4 · Rattlesnake 4.

Your card: Otter 0 · Rattlesnake 0.

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