Water is essential because people, plants and animals need it to live. It supports daily activities and helps sustain ecosystems.
Living things depend on water, and the chapter connects water with life on Earth.
Water can be found as liquid water and as ice. It can also occur as water vapour in the air.
The chapter discusses water in different forms and its movement through the water cycle.
Freshwater is found in sources such as rivers and lakes and is important for drinking and many other needs. Saltwater is found in seas and oceans and contains more dissolved salts.
The chapter distinguishes freshwater and saltwater sources.
Water evaporates, rises into the air, cools and condenses into clouds, and returns to the ground as precipitation. Water then collects or flows over land, and the cycle continues.
The water cycle describes water moving continuously between the land, water bodies and air.
Rainwater may flow over the land, enter the soil or collect in low places. Flowing water can shape the land and feed streams and other water bodies.
The chapter explains the movement of water and its role in shaping land.
Water is limited and is needed by people, plants, animals and ecosystems. Saving it helps ensure that enough remains for different needs.
The chapter presents water as a unique and limited essence of life.
Students can close taps properly, report leaking taps and use only the water they need. The school can also check its water storage and encourage everyone to save water.
These actions apply the chapter’s emphasis on water conservation to school life.
Freshwater habitats provide living spaces for many plants and animals. They also support wider ecosystems and are connected to the water people use.
The chapter links freshwater sources with habitats and life.
The community may have less water available for drinking, cooking, cleaning and growing food. Plants and animals that depend on local water sources may also be affected.
This follows from the chapter’s explanation that water is limited and supports many forms of life.
Students could observe where the water flows and where it collects after rain. They could share their findings with teachers and suggest ways to guide or collect rainwater safely, while protecting the area from waste.
The chapter encourages observing rainwater in the neighbourhood and thinking about water planning and conservation.
