Understanding the concept

Water is an incredibly important substance for all living things! Everything around us, from tiny plants to big animals and humans, needs water to survive. But where does all this water come from? The main source of all water on Earth is rain. When it rains, water fills up rivers, lakes, and even seeps into the ground to become groundwater, which we can access through wells. Rivers are natural flowing bodies of water that often start in mountains and flow towards the sea, providing water along their course. Wells are holes dug into the ground to reach this underground water. Besides these natural sources, humans also create reservoirs and dams to store water. Once we have water, we use it for so many things every single day. We drink water to stay healthy, use it for bathing and washing clothes to keep clean, and it's essential for cooking our food. Farmers use water to irrigate their crops, helping plants grow so we can have food. Industries also need water for manufacturing products. Understanding these different sources and uses helps us appreciate water and learn why it's so important to conserve it.

Tips for parents & teachers

• Encourage your child to observe and list all the ways they use water at home during a typical day.
• Discuss where the water they use at home comes from, whether it's tap water or from another source.
• After completing the worksheet, review incorrect answers together to ensure understanding and clarify any misconceptions.
• Extend the learning by having your child draw their journey of water from a source to their home.
• Prompt your child to think about what would happen if a particular water source dried up, to encourage critical thinking.
