Science class 5 chapter 6 full details

Olympiad exams are currently expected in all schools. Students are exposed to national competitions at a young age. Exams for the Science Olympiad concentrate on conceptual learning and logical reasoning. They give students a chance to compete against one another while also enhancing their understanding of their own abilities in any subject. In this article, you will get detailed information about science chapter 6 for class 5: Importance of Water.

Throughout India, the Science Olympiad is a well-known exam. This test consists of two levels. The first level is comprised of elementary scientific concepts. At the second level, students are tested on complex scientific theories. Students who successfully complete the first exam in the Olympiad move on to the second.

The school connects online and organizes the National Science Olympiad for students from all over the country. The National Science Olympiad is open to students in grades 1 to 12. Students who need student materials or have questions answered can register on School Connect Online’s website. School Connect Online provides Olympiad preparation study materials. School Connect Online offers free downloadable materials for NSO preparation, such as syllabus, sample papers, previous year question papers, important question papers, etc. Experts who have mastered the subjects and are familiar with the trends of Olympiad test papers solve resources such as sample papers, previous year papers, and so on.

Detailed notes about science chapter 6 for class 5: Importance of Water.


Water is an extremely valuable natural resource. Water is required for the survival of all living things. We can’t imagine a world without it. Water is required by animals and plants to complete their daily metabolic activities. Water is required for plants to synthesize their food through the photosynthesis process.

On average, a person consumes 600 to 700 liters of water per day. We can all go days without food, but we can’t imagine going a day without water; even plants become dry and shed their leaves without it.

Let us learn more about the significance of water.

What is the definition of water?

Water is one of the few natural resources that can be found in sufficient quantities. It is a requirement for the survival of life on the planet Earth. It’s commonly used for drinking, washing, bathing, cleaning, cooking, irrigation, and other industrial and domestic purposes.

Sources of Water

Water can be found in a variety of places. Water covers approximately 97 percent of the Earth’s surface. The following are the three main sources of water:


Water bodies such as wells and springs are examples of groundwater.

Surface water consists of various water bodies such as the sea, oceans, reservoirs, rivers, streams, ponds, lakes, and tanks.

The Value of Water

Water is required for a variety of daily activities, including:

Bathing, cleaning, cooking, drinking, and washing are examples of domestic activities.

Irrigation, farming, gardening, and frost control are all examples of agricultural applications.

Other Industrial Use Cases

Apart from that, we drink water for the following reasons:

  • Keep yourself hydrated.
  • Joints should be lubricated
  • Control your body’s temperature.
  • In the body, nutrients and waste are transported.
  • Water loss from the digestive tract and body tissues must be balanced.

Water Cycle

Water is always moving. The water cycle is a process that describes the continuous movement of water from the earth’s surface and is usually carried out in four stages. The sun controls the entire cycle, which is also known as the hydrological cycle.

Evaporation: At this stage, the sun’s heat heats the water in oceans and other bodies of water, causing it to evaporate as vapours, which rise to form clouds.

Condensation: Condensation occurs when the water vapour in the clouds cools.

Precipitation: The cooled water vapours in the clouds condense into droplets, which are then released as Precipitation back to the earth’s surface as rain or snow.

Collection: Rainwater collects on the ground and flows into the river, ponds, and well before returning to the sea.

As previously stated, water covers approximately 97 percent of the Earth’s surface. Only 2 to 3 percent of the water is safe to drink. The rest of the water is saltwater, and two-thirds of the freshwater on the planet is frozen in glaciers, making these water resources mostly inaccessible to humans.

As a result, we must all work to reduce the waste of this natural resource and conserve water for future needs.
