Water - Class 2 Science - New St. Mery English School

Water is one of the most important gifts of nature. All living things — humans, animals, and plants — need water to live and grow. We use water every day for drinking, cooking, bathing, washing clothes, and cleaning. Without water, life on Earth would not be possible.

Water comes from many sources such as rivers, lakes, ponds, wells, and rain. Rain is the main source of fresh water on Earth. It is very important for us to use water carefully and not waste it, because clean water is limited.

In this lesson, we will learn about the uses of water, its sources, and why we should save water. Water is life, so let us understand its value and protect it.
