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

Would they meet?

No. Wild rattlesnakes and jaguars 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.

Jaguar's home is the amazon rainforest, not the desert.

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

THE SCIENCE PICK

Jaguar!

A STOMP

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

On the desert, Jaguar wins. Jaguar 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: Rattlesnake 1 · Jaguar 7.

Your card: Rattlesnake 0 · Jaguar 0.

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