Sources of Water
Rain is the main natural source of water on Earth. Rainwater fills up rivers, lakes, ponds, and wells, which we use every day.
Uses of Water
We need water for drinking, cooking, bathing, washing clothes, and watering plants. Animals and plants also need water to live.
States of Water
Water exists in three forms: solid (ice), liquid (water), and gas (water vapour). Water changes its form when heated or cooled.
Water Conservation
Saving water is very important because pure drinking water is limited. We must never waste water and always fix leaking taps quickly.

Collecting and storing rainwater for future use is called rainwater harvesting. It is a smart way to save water for dry days.
