Flowing, flowing, never done!

Where do you get water from ? (Page- 91)

1. Do you get water delivered in a tanker? If yes, find out where the tankers bring water from. Does your water come from a well, river or lake near your village or city?

2. Do you know anyone who faces difficulty in getting water every day?

Ans: I know some people who face difficulty getting water every day. They have to walk long distances to fetch water from wells or rivers.

Water in Our Daily Lives (Page - 92)

Write 

1. List all the activities you can think of for which we need water.

Ans: Drinking, cooking, bathing, washing clothes, cleaning dishes, watering plants, flushing toilets, and cleaning the house.

2. How many mugs of water do you need to brush your teeth? How much water do you use to take a shower?

Ans: I need about one mug of water to brush my teeth and approximately 1 Bucket of water for a shower.

3. Have you ever faced a situation when you did not get any water? What did you do then?

Ans: Yes, there was a time when our water supply was interrupted due to maintenance work. We used stored water,  avoided activities like washing clothes, and fetched additional water from a nearby public tap.

4. Ask your Grandparents or any elder:

How did they get water? Did they use water in the same way as you do ?

Ans: They told me that they did not have taps like we do today. They had to fetch water from a nearby well or river.

How did they store water?

Ans:  They used big pots made of clay to store the water, and they were very careful not to waste it. They  said that they used less water than we do now because it was hard to get.

Write a short story about what you found out?

Ans: My grandparents told me that when they were young, there were no taps at home. Every day, they would walk to a well with pots to fetch water. They used a bucket to pull water from the well and carried it back home.

They stored the water in large clay pots and used it carefully, as getting water took time and effort. This story reminded me how lucky we are to have water so easily today.

Activity 3 (Page 94)

Put up an exhibition

1. Identify different vessels used to keep water in your home.

Stop for a Moment and Think ! (Page - 95)

Water comes down to earth as rain.

It slowly fills up our many sources—streams, rivers, ponds, lakes, wells, groundwater, etc.

From these sources we bring water to our homes in many ways.

We store it in many ways.

We use it in many ways.

What happens to water after we use it?

Ans: After we use water, it can become dirty. We should avoid using dirty water for drinking or cooking, but we can reuse it in other ways, like watering plants or flushing toilets. Some of the used water goes into drains and is treated before being released back into the environment. 

Activity 4 (Page -97)

Prepare a birdbath — offer water to birds in the hot summer months.

A birdbath contains water in a shallow plate for birds to drink and cool down.

• Take a shallow and wide container (an old big bowl or a base of an old pot or a bucket, less than 10 cm deep).
• Keep some stones in it for birds to perch. You may make the sides sloping by adding some smaller pebbles. Smaller pebbles also help insects to use this water.
• Add fresh water and keep the bowl in your yard, balcony, or terrace.
• Change the water frequently.
• Clean the birdbath with a scrubber twice a week. Do not use this scrubber for kitchen utensils; reserve it for the garden.

  

Let Us Reflect (Page - 98)

A. Write

1. You waited for rain and watched how raindrops fell to the ground. You collected rainwater and observed if it was clean or dirty. You saw what happened to the rainwater that fell in different places. Now write a few lines on your observations of the rain.

Ans: I observed that the rain started with small droplets, which gradually became larger. The rainwater collected in a clean vessel appeared clear, while the water collected from the ground looked muddy. On different surfaces, the rainwater either formed puddles or was absorbed into the soil. When the sun came out, the puddles slowly dried up, and the absorbed water seemed to disappear into the ground.

2. You found out the name and some information about a stream, river, well, pond, or lake near your place. Write it in a few lines: Is this water used for drinking? If yes, how is this water carried to your home? If it is not used, why not? Was it used in the past?

Ans: Near my place, there is a river called Yamuna. This water is used for drinking after it is treated in a water purification plant. The treated water is then transported through large pipes to water tanks in our locality, from where it is distributed to homes through a network of smaller pipes. In the past, the river water was used directly for drinking, but due to pollution, it now needs to be treated before use.

B. Draw

Draw a picture of your birdbath. Write the names of the birds and insects that come to drink water from your birdbath.

Ans:  The birdbath is a shallow bowl placed on a pedestal in my garden. It is filled with clean water and has a few stones for birds to perch on. The birds that come to drink include sparrows, pigeons, and occasionally a crow. Insects like bees and butterflies are also seen around the birdbath, especially on hot days.

C. Discuss (Page 99)

Water is very precious. We should be cautious about how we use it. We should not waste even a drop of water. Discuss among yourselves and list the activities in your house or outside, due to which water gets polluted or wasted. How can we avoid wastage of water? Think of three solutions with your group and write them in your notebook.

Ans:

Activities that waste water:

1. Leaving taps running while brushing teeth or washing dishes.
2. Overwatering gardens and plants.
3. Using excessive water for washing cars.

Solutions to avoid wastage:

1. Turn off taps when not in use, like while brushing teeth.
2. Water plants early in the morning or late in the evening to reduce evaporation.
3. Use a bucket instead of a hose to wash cars and clean driveways.
