chapter: 6 | Water | solutions | Class 4 | Evs |
I. Conceptual Understanding
1. Why do we need tanks?
โข Tanks are needed to store water for various uses like drinking, irrigation, and for cattle. They also help to increase the groundwater level and provide water during dry seasons.
2. How are tanks being polluted?
โข Tanks are polluted by activities like bathing, washing clothes, cattle, and vehicles in the tank, throwing household wastes and animal carcasses, using the tank as toilets, and immersing idols made with chemicals. Additionally, sewage water and chemical effluents from factories also contribute to pollution.
3. How should we conserve our tanks?
โข We should stop polluting tanks by avoiding harmful practices such as dumping waste and chemicals. Proper maintenance should be done by removing weeds, cleaning tanks regularly, and ensuring proper water channels to refill the tanks.
II. Questioning and Hypothesis
4. Ask your teacher what will happen if all the tanks dry up.
โข If all the tanks dry up, it would lead to water scarcity, affecting drinking water, agriculture, and cattle. Groundwater levels would decrease, and people would struggle for their daily water needs.
III. Experiments and Field Observations
5. With the help of your teacher, visit a nearby field. Observe how water is supplied to the fields. Draw a block diagram.
โข (This is a field activity where students are expected to visit a field and observe the water supply system, then create a diagram based on their observations.)
IV. Information Skills and Projects
6. Collect information about a tank in your village and write the history of the tank.
โข (This is a project-based activity where students are asked to gather information from elders or local sources about a village tank and document its history.)
V. Drawing and Model Making
7. Prepare a chart showing the water cycle.
โข (Students should create a chart that illustrates the process of evaporation, condensation, and precipitation, explaining how the water cycle works.)
water cycle
The water cycle, also known as the hydrological cycle, is the continuous process by which water moves through the Earth’s atmosphere, surface, and underground. It consists of several key steps:
1. Evaporation
- The cycle starts when the Sun heats up water in oceans, rivers, lakes, and other bodies of water, causing it to turn into water vapor. This process, known as evaporation, transfers water from the Earth’s surface into the atmosphere as gas.
2. Condensation
- As water vapor rises, it cools down and turns back into liquid, forming tiny droplets in the atmosphere. This process, called condensation, leads to the formation of clouds. When these droplets gather together, they create larger water droplets.
3. Precipitation
- When the clouds become heavy with water droplets, they release this water back to the Earth in the form of precipitation. Precipitation can be rain, snow, sleet, or hail, depending on the temperature and weather conditions.
4. Collection
- After precipitation, the water collects on the Earth’s surface in oceans, lakes, rivers, and groundwater. Some of it seeps into the ground, replenishing aquifers, while the rest flows into rivers and streams, eventually making its way back to larger bodies of water.
5. Runoff and Infiltration
- The water that falls on the ground can flow over the surface as runoff, joining rivers and streams. Some water also seeps into the ground, a process known as infiltration, which replenishes groundwater supplies.
6. Transpiration
- Plants absorb water from the soil and release it into the atmosphere through their leaves in a process called transpiration. This process also contributes to the moisture in the atmosphere.
Continuous Cycle
- This cycle repeats as the water evaporates again, forms clouds, and falls as precipitation. The water cycle is essential for life, as it distributes fresh water across the planet, helping to maintain ecosystems, weather patterns, and life itself.
The water cycle is a natural recycling system that keeps water circulating throughout Earth, making it one of the most important natural processes for sustaining life.
VI. Appreciation
8. Prepare some slogans to stop pollution of water.
โข Example slogans:
โข โSave water, save life!โ
โข โKeep our tanks clean for a healthy future!โ
โข โSay no to water pollution, yes to clean water!โ
โข โProtect water bodies, protect life!โ
Chapter: 7 | professions and service |

- Agricultural Officer โ Provides seeds, tools, and guidance on modern farming techniques.
- Bank Manager โ Offers loans at low interest rates to help farmers with financial support.
- Electrical Engineer โ Ensures power supply needed for operating pumps, machinery, and other equipment on the farm.
3. Write how a plumber helps you.
A plumber helps by installing and repairing water systems, such as pipes, taps, and drainage systems in homes and buildings. They ensure that we have access to clean water and that wastewater is properly managed, which is essential for hygiene and daily activities like cooking, cleaning, and bathing.
II. Questioning and Hypothesis.
4. What questions would you like to ask a grocer in your village about his/her profession?
Here are some questions I would ask a grocer in my village about their profession:
- Where do you get the fruits and vegetables you sell?
- How do you decide the prices for different items?
- What challenges do you face in your work?
- How do you make sure that the items you sell are fresh?
- What are the most popular items that people buy from your store?
III. Experiments and Field Observations.
5. Visit a cobbler in your village. Observe how he repairs the shoes.
I visited the cobbler in my village and watched how he repairs shoes. First, he looks at the broken shoe to see what needs fixing. Then, he uses glue to stick any parts that have come loose. If the sole is damaged, he carefully removes it and puts on a new one with glue and nails. He also uses a needle and strong thread to stitch any torn parts. Finally, he polishes the shoes to make them look new again. It was interesting to see how he works with his tools and makes old shoes useful again!
IV. Information Skills and Projects.
6. Collect pictures of tools used by different professionals from newspapers and prepare a scrap book.
To complete this activity, collect pictures of tools used by various professionals. Look in newspapers, magazines, or even online (with the help of an adult) to find pictures. Here are some ideas:
- Doctor’s Tools โ Stethoscope, thermometer, and blood pressure monitor.
- Tailor’s Tools โ Scissors, measuring tape, and sewing machine.

V. Drawing and Model making.
7. Draw and colour the picture of a sickle or any tool in your workbook.
VI. Appreciation.
8. How would you appreciate the services of a scavenger in your village?
I would appreciate the services of a scavenger in my village by saying thank you for the hard work they do every day to keep our surroundings clean. They collect garbage and keep the streets and public places tidy, which helps prevent the spread of diseases. I would also show respect by greeting them kindly, helping spread awareness about their important work, and encouraging others to keep the area clean so their job becomes easier. Their work is valuable, and we should respect and thank them for keeping our village safe and healthy.
9. Look at the pictures and write how you feel about them.
Looking at these pictures, I feel happy and appreciative. They show a farmer taking care of his buffalo by cleaning, feeding, and milking it. It shows the hard work and care involved in looking after animals that help us in our daily lives. The farmer looks gentle and kind to the buffalo, and the bond between them is heartwarming. This reminds me how important animals are in farming and how farmers work hard to provide us with milk and other resources. It also shows that taking good care of animals is essential and that we should respect both farmers and their animals.
