Round & round it goes

The WaterCycle

Water goes up, makes a cloud, falls down, and swims home. Then it does it all again — forever!

Evaporation

UP, UP, UP!

The sun warms the sea. Water turns into an invisible gas called vapour and floats way up into the sky.

Did you know? A puddle that vanishes has been lifted up by the sun!

The four big steps

Every drop on Earth walks the same four steps — over and over and over.

1

Evaporation

Water goes up

The sun heats the sea and the puddles. Water floats up as vapour — you can't see it!

2

Condensation

A cloud is made

Up high it is cold. Vapour cools down, huddles together and makes a fluffy cloud.

3

Precipitation

Rain comes down

The cloud gets heavy, heavy, heavy… then pitter patter! Rain, snow or hail falls down.

4

Collection

Water goes home

Rain fills the rivers, the lakes and the sea. Everything is ready to go round again!

2

Follow little Drippy

Press Next and go on one drop's journey. Grown-ups can press 🔊 to read it aloud.

💧

This is Drippy. Drippy is one tiny drop of water — and Drippy has been travelling round the Earth for millions of years!

3

Make it rain!

Slide the sun and the cold air and watch the sky answer back.

Hunt for it at home

The water cycle is happening in your kitchen right now. Look!

🫖

The wobbly stuff

Ask a grown-up to show you a boiling kettle. That clear wobble above the spout is water vapour — step 1!

🪞

The foggy mirror

After a hot shower the mirror is wet and cloudy. The vapour got cold and turned back into water — step 2!

💧

The shrinking puddle

A puddle gets smaller and smaller on a sunny day, even with nobody drinking it. The sun took it up!

🕸️

Wet grass, dry sky

Grass in the morning is wet although it didn't rain. Cold nights squeeze water out of the air. That's dew.

Rainbow hunting

After the rain, if the sun comes out, look for a rainbow. Sunlight + raindrops = colours!
