Why Does a Wave Stay in One Place While the River Rushes Through It?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why does a wave stay in one place while the river rushes through it?

The Big Idea

A river wave can stay in one place while the water rushes through it! It is called a standing wave. The water moves, but the shape stays the same.

Fast Water Meets a Rock

Step one: fast water meets an obstacle. Where fast water flows over a big rock or a ledge, it can pile up. The pile of water forms a wave.

The Shape Stays

Step two: the shape stays. New water keeps replacing the old water that rushes through. So the wave looks frozen even though the water moves fast.

Powerful Waves

Step three: powerful waves. Surfers on some rivers ride standing waves. Standing waves are powerful, so only trained river users should use them.

A Closer Look

Let's take a closer look at a standing wave! A rock or ledge sits in the river. Fast water rushes over it. The water piles into a wave. New water replaces the old water, again and again. So the wave stays in one spot.

Quick Facts

Quick facts! A river wave stays put because new water keeps replacing the old. Surfers on some rivers ride standing waves. Standing waves are powerful, so only trained experts should use them. Watch them from a safe spot, with a grown-up.

Think Like a Scientist

Now, think like a scientist! With a grown-up, run water from a tap onto a flat plate in the sink. Look for the small circle where the water jumps up. The shape stays still while water moves. Turn off the tap when you are done. You just made a standing wave!
