Pretend a otter and a sea lion meet in the coast. 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

Sea Lion!

A STOMP

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

On the coast, Sea Lion wins. Sea Lion likes the coast more. Otter 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 2 · Sea Lion 4 · ties 2.

Your card: Otter 0 · Sea Lion 0.

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