WATER O’ WATER!- TEXT

WATER O’ WATER!

ENVIRONMENTALSTUDIES

CBSE CLASS III

In this lesson we are going to learn about need and uses of water.

In this nani and her grandson were discussing about the uses for water. Let us see what there r discussing.

I’ll wash my face with water,

Said Munna to his Nani.

We all quench our thirst with water,

We are all alive because of water.

Water has been with us for ages,

Its story can fill so many pages!

From the first stanza munna learn that water is useful for all living thing. Without water living thing cannot survive on the earth. We use water in different ways.

We need water for drinking, bathing, washing, and for cleaning our houses. We get drinking water from rivers, lakes, well, rain etc.We store drinking in pots and tanks.

Let us see the second stanza………….. wat munna is s

Somewhere it is dew,

Somewhere it is snow,

steam is also water as you know.

Water has forms so many,

that is what says my Nani.

Dew is the change of water from a vapor to a liquid. Dew  is the water form of droplets that appears on thin, exposed objects in the morning or evening due to condensation. 

while you are going to morning walk you may observe the dew. They can cool the temperature by shading us from the sun's light and heat.

Snow is the small, soft, white pieces of ice that sometimes fall from the sky, when it is cold, you can also see snow in Shimla during winter months.

Steam is the form of water vapor. when water is boiled at 100C water changes in to gas. water has three states of matter. It can changes into solids, liquids and gases.

Let us see the third stanza……

The river flow, the waterfalls sing,

And water swells in lakes and springs.

Life on earth it has brought,

watered fields and life they got.

19. But when the water breaks in floods,

Great misfortune it always works.

The primary effects of flooding include loss of life, damage to buildings and other structures, including bridges, sewerage systems, roadways, and canals. Floods also frequently damage power transmission and sometimes power generation.
