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

Would they meet?

No. Stegosaurus and Rattlesnake 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.

Stegosaurus lives in places like grassland.

Rattlesnake

Rattlesnake's home is the north american deserts, not grassland.

No. Stegosaurus and Rattlesnake did not live at the same time. This meeting is pretend.

THE SCIENCE PICK

Stegosaurus!

A STOMP

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

On grassland, Stegosaurus wins. Stegosaurus likes grassland more. 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: Stegosaurus 4 · Rattlesnake 2 · ties 2.

Your card: Stegosaurus 0 · Rattlesnake 0.

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