Ans. The cap of the plastic bottles would float on water.

4.Have you seen that some things float on water while others sink? Think how this happens?
Ans. Yes, I have observed that certain things float on water while others sink. Everything displaces water equal to its volume. If the displaced water is more than the weight of a thing, then the thing floats, otherwise it sinks in water.

Do This and Find Out
Do this experiment in groups of four friends. Each group will need a big pot filled with water and the things listed in the table. Put each thing one-by-one in water and observe.
1.Mark (✓) for the things that float. Mark (X) for those that sink.

2.Find out from the other groups which things floated and which sank in the water?
Ans. A ball, a Styrofoam ball, etc. can float on water. An iron nail, a key, etc. will sink in water.

3.After doing the experiment, fill in the blanks:

    2. The empty plastic bottle……on water. The bottle filled with water……because……
    3. The aluminium foil…….when it was spread out. When pressed tightly into a ball it…….This may have happened           because…..
Ans.1. Iron nail sank in water but the katori floated. I think this happened because iron nail could displace less amount of water than what   was displaced by the katori.
2. The empty plastic bottle floated. The bottle filled with water sank because the filled bottle could displace less amount of water compared to its weight.
3. The aluminium foil floated when it was spread out. When pressed tightly into a ball it sank. This may have happened because aluminium foil spread out could displace more water compared to its weight.

Think and Find Out
1.Look at the area around your school. Are there any fields, farms, pucca roads, drains, etc. Is the area sloping, rocky or flat? Think, what will happen here when it rains? Where will the rain water go-into the drains, pipes or pits? Is some water also getting soaked into the soil?
Ans. Yes, there are fields, pucca roads and drains near my school. The area is somewhat sloping. When it rains, the rainwater easily goes into the drain and then to the nearby pond.

2.How do you think the rainwater that falls on the roof will reach the underground tank? Draw the path.
Ans. The water from the roofs goes to the pipes.
These pipes carry the water to the underground tank.

3.Have you ever faced a shortage of water in your area? If yes, then what was the reason for it?
Ans. Yes, we do face shortage of water in my area. This usually happens because of erratic supply from the Jal Board.Talk to your grandmother or any elderly person. Find out, when they were of your age.

4.From where did they get water for the house? Has there been a change now?
Ans. They used to get water from nearby rivers, ponds, wells, bavdis or hand pumps. The situation has changed now. We get water through pipelines of the ‘Jal Board’.

5.What kind of water arrangements were made for travellers—for example piau, mashak (leather bag) or any other? Now what do people do about water when they travel?
Ans. Earlier, kings and rich merchants used to build piau for travellers. Drinking water was served for free at these piaus. Mashak was used for carrying water. Nowadays, people carry bottled water when they travel.

Find Out
1.Is there a lake, well or stepwell near your house or school? Visit it and find out more about it.
How old is it? Who got it built?
Ans. Yes, there is a big pond near my house. People say that it is more than hundred years old. The king of the Raj period built it.

2.What kind of buildings Eire around it?
Ans. There are some ruins of the old palace and some new houses around it.

Ans. Yes, an annual boating festival is celebrated in this pond.

6.Is there any water today or is it dry?
Ans. The pond is full of water.

There are two old wells in the area where Punita lives. Her grandmother says that about fifteen-twenty years ago there was water in these wells. The wells could have dried up because:
• Water is being pumped up from under the ground, with the help of electric motors.
• The lakes in which rain water used to collect are no longer there.
• The soil around trees and parks is now covered with cement.
1.Is there some other reason for this? Explain. .
Ans. Apart from the reasons given above, there can be some other reasons also. Almost all the trees have been cut. The well is not being maintained.

The Story Today
1.Let us see the different ways in which the people manage water today. See the picture and discuss. Do you get water hat. If you get win your house by any of these ways?
Put a tick (right) on tater by some other way, write in your notebook.
• We get water from the Jal Board. We have connected a motor with the supply line. This helps us in storing water in the rooftop tank.
• The slum area near my house gets water from a Jal Board tanker which comes once in a day.
• In my grandfather’s village there are some hand pumps which draw underground water.
• I have seen some ladies in the village bringing water from the nearby canal.

1.Everyone has the right to live. Yet, is everybody getting enough water to live or even water to drink? Why is it that some people have to buy drinking water? Should it be like this? Water on this earth is for one and all. Some people draw out water from the ground by deep borewells. How far is it correct? Have you ever seen this? Why do some people put a pump directly in the Jal Board pipe line? What problems would other people face due to this? Do you have any such experience?
Ans. It is a harsh fact that everybody is not getting enough water to even drink. Drinking water is scarce and hence some people have to buy drinking water. It should not be like this. Drawing water by deep borewells is not a correct practice. I have seen many rich people, installing deep bore wells. Some people also directly put a pump in the Jal Board pipe line. Due to this, other people do not get sufficient water. In most of the houses in my colony, people have put pump directly into the Jal Board pipe line.

An old pond was cleaned of debris and was made deeper. People also planted trees around the village. This helped them to solve their water problems.
