Pretend a rattlesnake and a sea lion meet in the coast. Look at the facts. Then you pick.

Would they meet?

No. Wild rattlesnakes and sea lions 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.

Playful and noisy.

  • Sea Lion is big and not very fast.

Family: Fur seals and walruses.

Who would you pick for size?

TOOLKIT!

TOOLS

Rattlesnake

8 km/h

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

Sea Lion

30 km/h

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

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

Who takes the speed card?

Meeting biome: the coast. Colored land is where each animal actually lives.

Rattlesnake

Not their home · Lives in North America

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

Sea Lion

This is home · Lives in North America

Sea Lion lives in places like the coast.

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

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. 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 4 · Sea Lion 4.

Your card: Rattlesnake 0 · Sea Lion 0.

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

Send this fight

A friend can read the same facts.
