Class 2

🎯 Learning Objectives

📖 Let Us Begin!

Water is very important. We cannot live without water. We drink water, cook with water, and bathe with water.

Plants and animals also need water to live. Water is a precious gift of nature.

Let us learn about water!

Uses of Water

We use water in many ways every day:

We drink water to stay healthy. We cook food with water. We bathe with water to keep clean. We wash clothes and utensils with water. We water plants with water. Farmers use water to grow crops.

Sita counted how many times she used water in one morning. She drank water, brushed her teeth, bathed, and helped water the plants. Water is used so many times!

Sources of Water

Where does water come from? Here are the main sources:

SourceAbout It
RainRain falls from clouds. It fills rivers, ponds, and wells.
RiverRivers carry water from mountains to the sea. We get water from rivers.
WellWater is found under the ground. We dig wells to get it.
Tap / PipeWater comes to our homes through pipes from a water tank or river.
Pond / LakePonds and lakes collect rainwater. Animals drink from them.

Clean Water and Dirty Water

Clean water is safe to drink. It has no colour, no smell, and no dirt. We get clean water from taps and filtered water.

Dirty water has mud, germs, or waste in it. We should never drink dirty water. It can make us sick.

Always drink clean, filtered water. If water looks muddy or smells bad, do not drink it!

How to Save Water

Water is precious. We must not waste it. Here is how we can save water:

Close the tap when not using it. Take a short bath. Do not let water drip from taps. Water plants with a mug, not a pipe. Tell elders if a tap is leaking.
