Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How does a chuckwalla lock itself into a rock crack?

The Big Idea

A chuckwalla hides in a rock crack. And then it puffs up! Why?

Desert Lizard

Step one: Desert Lizard. The chuckwalla is a large desert lizard of the southwestern United States. It's wide and flat, which helps it fit in cracks.

Puffing Up

Step two: Puffing Up. When it feels disturbed, it squeezes into a narrow crack between rocks. Then it gulps air to puff up its body, wedging itself tightly in place.

Can't Be Pulled

Step three: Can't Be Pulled. This stops other animals from pulling it out. It breathes out later to slip free. It's a clever way to hide.

Think Like a Scientist

Now, think like a scientist! With a grown-up, put a deflated balloon in a clear cup with its opening over the rim. Blow it up. Notice how it presses against the walls. Try to pull it out. Let the air out to free it.
