Water is essential for every living organism. We need water to drink, cook, clean and bathe. We also require this natural resource for agriculture, industries and transportation as in boats and ships.
The Earth is covered with 70% water and often called the ‘Blue Planet’. Even though we have so much water on the earth, only 1% is usable as the rest is either salt water, as found in seas and oceans or is frozen in ice-caps.
With an increase in population, the demand for this limited resource is also increasing. Today, water scarcity is a problem faced by many people throughout the world. It is high time we take steps to use this important resource judiciously so that we have enough water for everyone in the future. Teachers must inculcate this value and awareness among the children. This lesson plan has been developed with that objective in mind.

Sir C.V. Raman is an Indian physicist. He was awarded the Nobel Prize in 1930 for his work on molecular scattering of light and for the discovery of the Raman Effect. In this present lesson Raman vividly made an effort to bring about the importance of water. Since the time immemorial, man has sought in vain for an imaginary elixir of life, the divine Amrita. A draught of amrita was thought to confer immortality. But in the words of Sir C.V. Raman, the true elixir of life the plain water.
Sir C.V Raman recollects the day he was standing on the line which separates the Libyan Desert from the valley of the Nile in Egypt. On one side was visible a sea of billowing sand without any life and on the other side lay one of the greatest, most fertile and densely populated areas to be found anywhere on the earth. It was teeming with life and vegetation. It was due to the water of the river Nile. The ancient civilization of Egypt was created and sustained by the life giving waters which comedown year after year with unfailing regularity. He gives this example to emphasize that the common water is the most potent and the most wonderful thing on the face of our earth.
I hope its help you....!!! :)
