Journey of Rain

Rain Drops

Drip drop drip drop, they drop from the sky

Drip drop drip drop, they fall on the ground

Everywhere with a lovely sound

Drip drop drip drop, they seep into the ground

To grow healthy saplings all around

On hot sunny days, they go back to the sky

To come again on another cloudy day

Drip drop drip drop, they drop all the way

To keep all of us happy

Water from Glaciers

A large glacier in the mountains — A glacier is a slow-moving block of ice.

A water drop character on a mountain — I am a water drop from the snowy mountains. I flow from the glacier when the weather becomes warm.

Small streams forming from melting snow — From the glacier many of us join together to form small streams.

A river flowing through a valley — Many mountain streams join together to form a river.

A cascading waterfall — Sometimes rivers or streams flow down as waterfalls.

As a river, I continue my journey across forests, villages and cities. Farmers use me for farming and people use me for drinking, cooking and for other needs. I finally reach the sea.

Sources of Water

Raindrop character I am a raindrop. I fall on the earth and fill ponds, lakes and rivers. Rivers flow while lakes and ponds do not. Lakes are bigger than ponds.

I fall on the ground and seep underground too. People dig wells and borewells to reach me. They also use pumps to lift me up from the ground. People use me for their needs.

Think! Why do lakes and ponds have less water in summer? Discuss.
