Why Do Lizards Switch Between Sun and Shade All Day?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do lizards switch between sun and shade all day?

The Big Idea

A lizard is cold-blooded, so it uses the outside world to set its body temperature! In the morning it basks on a warm rock to heat up. When it gets too hot, it dashes into shade or a burrow.

Warm Up

Step one: warm up. On a cool morning, a lizard basks on a sunny rock. The warmth gives its body energy to move fast.

Cool Down

Step two: cool down. When the lizard gets too hot, it runs to shade or a burrow. It does not sweat the way people do, so it must use the shade.

Stay in Range

Step three: stay in range. By switching between sun and shade all day, the lizard keeps its body within a safe temperature range. It is like using a thermostat with its feet.

A Closer Look

Let's take a closer look! A sunny rock gives warmth. The lizard lies flat to soak up the heat. Shade cools it when it is too warm. A warm lizard can run fast and hunt well. Too cold or too hot makes it slow.

Quick Facts

Quick facts! A lizard that gets too hot or too cold cannot hunt or run well. Cold-blooded animals use less food than warm-blooded ones. A lizard may make many trips between sun and shade each day. Watch wild lizards from a distance, and never touch or chase wildlife.

Think Like a Scientist

Now, think like a scientist! With a grown-up, watch a lizard, bug, or butterfly from a distance for ten minutes. Notice whether it chooses sunny or shady spots. Never touch or chase wildlife. Write down what you saw.

Outro

Lizards move between sun and shade to keep their bodies just right. Science is amazing! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books. Available for purchase or download! Bye for now!
