The Water Cycle

This is a short and simple write up on the water cycle which can be read out to children just like you would read out a story. Make you sure you modulate your voice and make it interesting for the child as you read.

Have you ever wondered how it rains?

How does water come down from the sky?

Do you know that the water that comes down from the sky was once here on earth?

In fact, it stays on earth for a while and then goes back to the sky. It comes down again when it rains and goes back up again. This goes on and on as a cycle. It is called the water cycle.

This is the story of the water cycle.

The sun shines and gives out heat.

The heat from the sun reaches the water that is present in all the ponds, lakes, rivers and oceans.

This heat causes the water to turn into water vapour or steam.

We cannot see this water vapour. It has no form or colour or smell.

The water vapour then rises up into the air

Once up there, it becomes cool and turns into droplets of water.

These droplets of water gather together and from the clouds that we see in the sky.

When a lot of water droplets are held together, the clouds become heavy. So, the air cannot hold them up in the sky any longer.

When this happens, it starts raining and the water in the clouds comes back to earth.

The rain water falls back into the ponds, lakes, rivers and oceans.

A pat of it also seeps into the earth and becomes ‘ground water’. This ground water is  used up by plants and animals.

The water that comes back to the ponds, lakes, rivers and oceans goes back to the sky again as water vapour and comes down in the form of rain.

This cycle goes on and on. The same water goes up and comes down all the time.

This is the water cycle.
