Year 6 Unit 2.2 Water Conservation

Water is essential for survival and covers over 70% of the Earth’s surface, with more than 97% found in oceans. Fresh water makes up less than 3% of the Earth’s total water supply, with more than 68% of that being found in ice and glaciers, and the remaining 30% as groundwater. Only a small fraction of fresh water, less than 0.3%, is found in rivers, streams, lakes, swamps, and ponds. Please identify the sources of fresh water in the pictures and check the corresponding box.

There are additional sources of water, which are created by humans. The following images display examples of man-made sources of water. Please identify and drag them into the corresponding box.

Desalination plants are another source of man-made water. The accompanying image depicts a desalination plant. The following paragraph will describe how seawater can be converted into drinking water and other uses.

Water is essential for the survival of living organisms, including plants. The diagram below illustrates how plants utilise water. Please carefully study the diagram and accompanying passage, then answer the questions provided.

Plants create their own food through a process called photosynthesis. They combine water from the soil and carbon dioxide in the air with light energy in the leaves to produce food. In addition to food, this process also results in the release of oxygen into the air.

For plants to grow well, they require minerals, which are transported to various parts of the plant through water.

Animals require water in order to survive. The diagrams below illustrate the human transport system. Please examine the diagrams and provide answers to the following questions:

Water is essential to our bodies, composing 60% of our overall makeup. We consume approximately 2 liters of water daily. Water serves a number of functions in our bodies, including the transportation of vital nutrients and oxygen to all areas of the body, regulation of body temperature, and moisturizing of our skin, eyes, and nasal passages.

Questions:

What percentage of our body is composed of water?

Water is essential to our bodies, composing 60% of our overall makeup. We consume approximately 2 liters of water daily. Water serves a number of functions in our bodies, including the transportation of vital nutrients and oxygen to all areas of the body, regulation of body temperature, and moisturising of our skin, eyes, and nasal passages.

Questions:

What are some of the functions of water in our bodies?

Animals require water not only for survival, but also for reproduction. Fish, for example, lay their eggs in water and spend their lives submerged. Similarly, frogs and toads lay their eggs in water and also spend a portion of their lives under water.

Questions:

What do animals require in addition to food and air in order to survive?

Animals require water not only for survival, but also for reproduction. Fish, for example, lay their eggs in water and spend their lives submerged. Similarly, frogs and toads lay their eggs in water and also spend a portion of their lives under water.

Questions:

Where do frogs and toads lay their eggs?

We consume a significant amount of water, but unfortunately, a considerable amount of it gets wasted. It is crucial to conserve water to ensure that clean water is always available for daily use. At home, we can take the following actions to conserve water. Please identify the actions using their corresponding captions.

Although 70% of the Earth’s surface is covered with water, only less than 3% is fresh water. Fresh water can be found in rivers, lakes, ponds, glaciers, and underground. It is crucial that we protect our water resources, such as rivers, lakes, and underground, from pollution. Please read the passage below and answer the following questions.

Many sources of fresh water are polluted with waste materials from homes, industries, agriculture, and soil erosion. Polluted water can cause health problems and harm or even kill fish, birds, otters, and other animals that depend on the water for survival.
