Pretend they meet in forest. Dinosaurs lived long ago. Look at the facts. Then you pick.

Would they meet?

No. Polar Bear and T. rex did not live at the same time. This meeting is pretend.

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

T. rex!

A STOMP

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

On forest, T. rex wins. T. rex likes forest more. Polar Bear 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: Polar Bear 3 · T. rex 5.

Your card: Polar Bear 0 · T. rex 0.

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