Class 5 EVS Chapter 1 Notes Water The Essence of Life
Class 5 Water The Essence of Life Notes
→ Freshwater: Water that is not salty and is safe for drinking and everyday use. It is found in rivers, lakes, ponds, and underground.
→ Salt Pan: Large flatlands where seawater is dried to collect salt.
→ Saltwater: Water that contains a lot of salt, and not suitable for drinking. It is mostly found in oceans and seas.
→ Water Cycle: The continuous movement of water in nature in which water evaporates from water bodies, forms clouds, and falls back to Earth as rain.
→ River: A natural stream of freshwater that flows across the land and usually ends in a sea or ocean.
→ Lake: A large body of freshwater surrounded by land.
→ Groundwater: Water that is stored deep underground in the soil and rocks. It can be drawn using wells, borewells, and handpumps.
→ Pond: A small body of still water, smaller than a lake, usually natural or manmade.
→ Groundwater Recharge: The process by which rainwater soaks into the ground and refills underground water sources.
→ Soak Pit: It is a covered hole in the ground that helps water soak into the soil.
→ Concrete Road: Roads in cities that are made using a mixture of cement, gravel, and water.
→ Paved Area: A place that is covered with materials like concrete, bricks, or tiles. It is usually flat and used for footpaths or parking spaces.
→ Surface Water: Water found on the surface of the Earth in lakes, rivers, ponds, and reservoirs.
Amazing Facts
- ‘Johods’ in Rajasthan are traditional small earthen dams built to collect rainwater and recharge groundwater.
- Wular Lake in Jammu and Kashmir is one of the largest freshwater lakes in Asia. It helps regulate river flow to prevent floods.
- The Fishing Cat, found in India’s wetlands, has partially webbed paws, making it an excellent swimmer who dives for fish.
- The Keibul Lamjao National Park in Manipur is the only floating national park in the world. It is famous for its unique ‘phumdis’ (floating islands) and the endangered Sangai deer.
- The world’s tallest statue is the ‘Statue of Unity’ in India, standing 182 metres tall.
- Hiware Bazar in Maharashtra is a successful example of a water-positive village. Local communities have contributed to its watershed management and rainwater harvesting.
- India’s first water museum – Jal Shakti Museum in New Delhi – celebrates India’s water heritage and innovation, inspiring citizens to conserve water.
→ Marshy Land: Wet and soft land that is often covered with water. It supports special plants and animals adapted to wet conditions.

→ Dune: A hill of sand formed by the wind, usually found in deserts.
→ Pincer: Some insects have a claw-like body part used for defence, catching food, or other tasks.
→ Edge Plants: Tall and grass-like plants that grow along the edges of ponds or lakes, such as reeds.
→ Free Floating Plants: Plants that float freely on the surface of water, such as water hyacinth.
→ Rooted Floating Plants: Plants that are rooted in the pond bed but have leaves and flowers floating on the surface, such as lotus and water lily.
→ Aquarium: A glass tank where aquatic plants and animals are kept and observed.
→ Waterproof: A material or surface that does not allow water to pass through, such as the waxy coating on leaves.
→ Aquatic Plants: Plants that grow in or around water and have special features like floating leaves, waxy coatings, or long roots.
→ Aquatic Animals: Animals that live in water and are adapted to swimming, breathing, or surviving in aquatic habitats.
→ Watershed Management: The careful planning and conservation of water resources in a particular area to prevent water shortage and improve supply.
→ Rainwater Harvesting: The method of collecting and storing rainwater for future use, especially to recharge groundwater.
Water The Essence of Life Class 5 Notes
It is raining. Afreen rushed to the window where Jyoti was already watching tiny raindrops slide down the glass. “Where do you think all this water comes from, and where does it go?” asked Afreen. Come, let us follow the journey of water. But first, let us see how much water there is on Earth.
Although most of the Earth’s surface is covered with water, the majority of it is salty, leaving less
amount of freshwater. All living beings-people, animals, birds, and plants-depend on freshwater to survive. It is essential for drinking, growing crops, and carrying out daily activities. Many plants and animals also live in freshwater. Without water, life would not be possible.
Now, imagine if all the water on earth were in this glass, then the freshwater would only be as much as in a teaspoon!
