What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why can cold lake water be dangerous even on a warm day?

The Big Idea

Lake water can be cold even on a hot day! That can be dangerous. Why?

Still Cold

Step one: Still Cold. Lake water can stay surprisingly cold for months after the air warms up. A hot beach day doesn't mean the water is warm.

Cold-Water Shock

Step two: Cold-Water Shock. Jumping into cold water can make you gasp and breathe fast. Arms and legs can get weak quickly, and that's called cold-water shock.

Staying Safe

Step three: Staying Safe. Wear a life jacket, enter slowly, and swim with a buddy near shore. If you fall in, stay calm, float on your back, and call for help.

A Closer Look

Let's take a closer look! Always. Ease in. Stay close. Stay calm.

Quick Facts

Quick facts! Water pulls heat from your body about twenty-five times faster than air does. Cold makes you gasp. Wear a life jacket. Float and call for help.

Think Like a Scientist

Now, think like a scientist! Fill a bowl with ice water. Dip your hand in for ten seconds. Take it out and dry it. Notice how it feels. How quickly did it get numb?

Outro
