When you're thirsty, nothing is better than a nice cool drink of water!

法助動詞 A2

Oh, and it looks like my plant could use a drink, too!

Did you ever stop to think about where our water comes from?

Sure, when you get a drink of water, it might come from a faucet or a bottle…and I give

my flower here water from a watering can...

The water that comes out of the faucet and the watering can may once have been part of

a cloud...or a snowflake...or even the ocean!

...and it's because of something called the water cycle.

Now, a cycle is a set of steps that repeat over and over.

When you get to the last step in a cycle, you go back to the beginning and go through

For example, every year there are four seasons...spring, summer, fall and winter.

And when when winter's over...it's time for spring again!

We go back to the beginning of the cycle.

In the water cycle, all of the water on Earth goes through a set of steps that repeat over

Let's start with the step in the water cycle where we open up our umbrellas…

But a lot of it flows into little creeks and streams, and then ends up in rivers, lakes...and

And then something really interesting happens.

You might have noticed that after it rains, some water is left on the ground, like in

It seems like it's there one day, but then, after a little while ...it's gone!

When the sun comes out and the ground gets warm, water can change into a different form.

We call this form water vapor...and water vapor is a gas.

The air we breathe, it's a bunch of different gases mixed together!

And like the gases that make up air, you can't see water vapor gas.

When the sun shines on rivers, lakes, and oceans, some of the water changes into water

And then the water vapor goes up high...very high...up into the sky.

So, when the water vapor gets high enough, it starts to get cool.

And as water vapor cools down ... it changes back into little drops of liquid water.

You can actually see water vapor change into water drops right at home!

All you need is a mirror or window...and your mouth!

Put your face close to the mirror or window, open your mouth nice and wide...and breathe

That's because there's water vapor in your warm breath.

And when the water vapor in your breath touches the cool glass, it changes into teeny tiny

A lot of the droplets together make the glass look cloudy.

And up in the sky, a lot of water droplets together make … clouds!

When there's a lot of water in a cloud, the cloud starts to get darker.

And as the clouds get grayer, the water in them gets heavier.

When the water gets too heavy, it falls...right back out of the clouds, as rain.

And rain is where we started in the cycle!

We made it all the way back to the beginning!

Now the water cycle can start over again.

All the water on our great big Earth goes through this same cycle, over and over.

And soon that water ends up in a river, lake, or ocean.

From there, it heats up and turns into vapor.

And when the vapor rises into the sky and cools off, it comes right back down!

So the water that you drink, and the water that's in my watering can right now, might

once have been part of a raindrop that fell into the ocean on the other side of the world!

Think about that next time you take a drink!

Do you have a question about the weather...or anything else?
