Every Drop Counts Class 5 NCERT EVS Chapter Guide

Chapter Overview: Why Every Drop Counts

This chapter teaches that water is a shared natural resource, not an unlimited gift. Some families get water easily from taps, while others walk long distances or wait for tankers. The difference may happen because of low rainfall, dry climate, overuse of groundwater, broken pipes, pollution, or poor storage. The chapter also reminds us that people in the past built clever structures to collect rainwater. When we understand how water reaches our homes and how quickly it can be wasted, we become more careful citizens. In EVS, the main idea is not to memorise names only, but to observe, compare and think: Where does my water come from? How is it stored? Who may not have enough?

Important Terms in Every Drop Counts

Water scarcity

A situation where people do not have enough clean water for drinking, cooking, washing, farming or animals.

Rainwater harvesting

Collecting and storing rainwater so it can be used later or allowed to seep into the ground.

Stepwell

A deep well with steps going down to the water level. People could climb down as the water level changed.

Johad

A small traditional water storage structure, often made in villages to collect rainwater and recharge groundwater.

Groundwater

Water present below the ground in spaces between soil and rocks. Wells and handpumps often use groundwater.

How Traditional Rainwater Storage Works

1. Rain falls on land or roofs — In dry places, people know that rainfall may come only for a short time. So they do not let rainwater simply flow away into drains.
2. Water is guided to a storage place — Slopes, channels or roof pipes carry the water towards a tank, johad, pond or stepwell. This is like giving rainwater a safe path.
3. Silt and dirt settle down — When water stands in a tank or pond, heavier mud particles can settle at the bottom. Cleaner water remains above for careful use.
4. Water is used slowly through the year — People draw only what is needed for drinking, cooking, animals or crops. Because the supply is limited, wasting water is avoided.
5. Some water seeps underground — Stored water can slowly go into the soil and recharge groundwater. This helps wells and handpumps have water for a longer time.

Worked EVS Examples from Daily Life

• Example 1: A tap is dripping in a school wash area. Step 1: Observe the problem: even small drops fall again and again. Step 2: Think of the effect: a bucket may fill after some time, which means clean water is being wasted. Step 3: Decide action: close the tap tightly or inform a teacher/helper if it is broken. Learning: water conservation starts with noticing small wastage.
• Example 2: A village gets rain for only a few weeks. Step 1: The villagers cannot depend on rain every day. Step 2: They build a johad or tank to collect rainwater. Step 3: The stored water helps people and animals during dry months. Learning: storing water during rainy days helps during water shortage.
• Example 3: Two homes wash vegetables differently. Home A washes under a running tap; Home B washes in a bowl and uses that water for plants. Step 1: Compare use: running tap uses more water. Step 2: Check reuse: bowl water can be reused if it has no soap. Step 3: Choose better habit: Home B saves clean water. Learning: reuse is an important part of water care.

Exam Tip: Write Answers Like an EVS Observer

In Class 5 EVS, answers should show observation and reasoning. If the question asks why old water structures were useful, do not write only one word such as storage. Explain that they collected rainwater, helped during dry months and sometimes recharged groundwater. For value-based questions, include practical actions: closing taps, repairing leaks, reusing water where safe, and not dirtying ponds or wells.

Common Mistakes to Avoid

• Do not think water scarcity happens only because there is no rain. Overuse, pollution, leakage and poor storage can also create shortage.
• Do not write that all stored water is safe to drink. Drinking water must be clean and protected from dirt and germs.
• Do not confuse a stepwell with an ordinary well. A stepwell has steps so people can go down as the water level changes.
• Do not treat water saving as only an adult job. Children can close taps, report leaks and avoid wasting water while brushing or washing.
• Do not memorise names without purpose. Always connect johad, tank and stepwell to rainwater storage and careful use.

Practice Questions with Solutions

• Q: Why is the chapter called Every Drop Counts? A: Step 1: The chapter shows that water is necessary for drinking, cooking, cleaning, farming and animals. Step 2: It explains that many places do not have enough clean water all the time. Step 3: So even a small amount of water should not be wasted. Final answer: The chapter is called Every Drop Counts because every small drop of water is valuable and should be saved.
• Q: Name two traditional methods of storing water and explain one use of each. A: Step 1: Recall traditional structures from the chapter, such as stepwells, johads and tanks. Step 2: Choose two: stepwell and johad. Step 3: Explain their use: a stepwell lets people reach stored water by steps, and a johad collects rainwater and helps recharge groundwater. Final answer: Two traditional methods are stepwells and johads. Stepwells store water at a depth, while johads collect rainwater for later use and groundwater recharge.
• Q: Riya leaves the tap running while brushing. What should she do and why? A: Step 1: Identify the waste: clean water is flowing even when it is not needed. Step 2: Suggest the correct habit: she should close the tap while brushing and open it only when needed. Step 3: Give the reason: saved water can be used for important needs and helps reduce wastage. Final answer: Riya should close the tap while brushing because running taps waste clean water unnecessarily.
• Q: How can rainwater harvesting help a dry village? A: Step 1: In a dry village, rainfall may be low or seasonal. Step 2: Rainwater harvesting collects water from rain instead of letting it flow away. Step 3: Stored water can be used later, and some of it can seep into the ground to support wells. Final answer: Rainwater harvesting helps a dry village by storing rainwater for dry days and recharging groundwater.
