Think what would Happen if

1. Ayesha put a puffed puri in a bowl of water. Would it sink or float?

Ans: It would float on the surface of the water.


2. You put a steel plate on water. Would it sink or float? What would happen to a spoon?

Ans: When you put a steel plate in water, it would sink and a spoon would also sink because metals are generally denser than water.


3. Would the cap of a plastic bottle sink or float on water?

Ans: The cap of a plastic bottle would typically float on water. 


4. Have you seen that some things float on water while others sink? Think how this happens!

Ans: Things float or sink on water based on their density. Objects denser than water sink because they displace less water than their weight. Objects less dense than water float because they displace water equal to their weight.


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. Write your observations in the table given below:

1. Mark [✓] for the things that float. Mark [✕] for those that sink.

  1. Plastic bottle cap

  2. Plastic cup

  3. Wooden stick

  4. Cork

  5. Ping pong ball

Items that typically sink in water:

  1. Steel plate

  2. Iron nail

  3. Coin (like a penny or nickel)

  4. Key

  5. Rock


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

1. The iron nail ______ in water but the katori ______. I think this happened because _________________________________

Ans:The iron nail sank into water, but the katori floated. I think this happened because the iron nail displaced less amount of water than the katori displaced.

2. The empty plastic bottle ______ on water. The bottle filled with water ______ because ______________________________

Ans: The empty plastic bottle floated on water. The bottle filled with water sank because the bottle filled with water displaced less amount of water than the empty bottle displaced.


3. The aluminium foil ______ when it was spread out. When pressed tightly into a ball it __________. This may have happened because ____________________________________

Ans: The aluminium foil floated when it was spread out. When pressed tightly into a ball, it sank. This may have happened because when pressed tightly into a ball it would have displaced less amount of weight than the aluminium foil spread out.


Is it Magic?

1. Take some water in a glass. Put a lemon in it. Now keep putting salt in the water, half a spoon at a time. Were you able to float your lemon in water?

Ans: Yes, adding salt to water increases its density, which can make objects like a lemon float instead of sinking. This happens because saltwater becomes denser than freshwater, providing more buoyant force to support the lemon's weight.


2. What do you think, the lemon floated in salty water, because……

Ans: the salt increased the density of the water.


What Dissolved, What Did Not?

1. Suggest some ways to Hamid for quickly dissolving sugar

Ans: Here are some ways for Hamid to quickly dissolve sugar:

  1. Stir vigorously with a spoon.

  2. Heat the water (if applicable) to increase solubility.

  3. Crush the sugar into smaller granules before adding it to water.


Do this Experiment

1. Make groups of four friends. For the experiment you will need 4-5 glasses or bowls, spoons, water, and the things listed in the table. Take some water in each glass. Now try to dissolve one thing in one glass. Observe what happens and note in the table


Things

Did it dissolve or not?

What happened after keeping for 2 minutes?

1. salt

Yes

Salt got mixed well with the water.

2. Soil

No

Soil does not get mixed with water. Instead it settles down at the bottom.

3. Chalk powder

No

Chalk powder too settles down at the bottom by turning the water into white colour.

4. 1 spoon milk

Yes

Milk gets mixed with water by turning the water into white colour.

5. Oil

No

Oil doesn’t get mixed with water instead it floats on water.


Tell

1. Could you see the salt after it dissolved in water? If no, why?

Ans: No, you cannot see the salt after it dissolves in water because salt is soluble in water


2. Does that mean that now the water does not have salt? If it has, then where is the salt?

Ans: Yes, the water still contains salt after it dissolves. The salt ions are dispersed throughout the water, making a solution where salt is present but not visible.


3. What difference did you see – in the water with salt, and the water with chalk powder – after keeping for some time?

Ans: After some time, the water with salt remained clear, while the water with chalk powder appeared cloudy.


4. Which of the two would you be able to separate from the water by straining with a cloth – salt or chalk powder?

Ans: You would be able to separate chalk powder from the water by straining with a cloth, but you cannot separate dissolved salt from water using this method.


5. Do you think the oil got dissolved in the water? Why do you think so?

Ans: No, oil does not dissolve in water. It just floats on the water.

Racing drops


Ayesha put two drops of oil on the lid of her tiffin box. Next to that, she put two drops of water and two drops of sugar solution. She tilted the lid. She saw some drops slid down quickly, while some were left behind.


1. You also try to do the same and then tell – which drop went ahead? Why did it slide faster?

Ans: Water drops slide quicker than oil or sugar solution drops because both oil and sugar solution are thicker than water and stick to the box, making sliding difficult.


Where did the Water Go?

One day Ayesha’s mother put some water to boil on the stove for making tea. She got busy with something and forgot about it. When she remembered and came to check, she found very little water left in the pan.


1. Think where did the water go?

Ans: The water evaporated, leaving less water in the pan.


2. Why did Chittibabu and Chinnababu keep their mango jelly in the sun?

Ans: Chittibabu and Chinnababu placed their mango jelly in the sun to evaporate the water in it.


3. At your house, what things are made by drying in the sun?

Answer: At my home, we make papad, pickles, sabudana papad, and mango jelly by drying them in the sun.


What we have Learnt

1. You have washed your handkerchief and you want to dry it quickly. What all can you do?

Ans: To dry a washed handkerchief, first, squeeze it, spread it out properly, and leave it in the sun. You can also use ironing to dry it.


2. What things do you put in water to make tea? Which of those things dissolves in water?

Ans: To make tea, you put tea leaves (or tea bags), sugar, and milk in water. Out of these, sugar dissolves in water.


3. You have been given some mishri pieces (lumps of sugar). Suggest some ways to dissolve them quickly.

Ans: We can dissolve mishri pieces quickly in two ways.

  • By stirring powdered mishri in water.

  • By heating the mixture of water and crushed or powdered mishri.

4. What happened when Ayesha flattened dough and sank in water?

Ayesha stood there watching her mother roll the puri out and drop it into the hot oil. The puri slid to the bottom of the pan first, she noticed. The puri rose to the surface and began to float in the oil as it puffed up. One puri did not puff up or float as well as the rest. Ayesha took some dough and rolled it into a ball after seeing this. She pressed it flat and placed it in a bowl of water. Unfortunately, it sank to the bottom and remained there.

5. What happened when soap slipped in water?

Ayesha took a bath in the evening. “Ayesha, you have spilled the soap in the water again,” her mother said as she walked out. Remove it and place it in the soap case.” Ayesha was rushing and the soap case slipped from her grasp. It began to float on water. Ayesha placed the soap in the soap case with care. Even with the soap in it, she noticed that the case continued to float.

6. What happened when Ayesha put salt while boiling eggs?

Ammi had a fever when Ayesha woke up in the morning. Abbu poured some tea and went to Ammi's house to offer her medicine. “You boil eggs,” he told Ayesha. Add some salt to the water as well.” Ayesha poured some water into a pot. She accidentally added too much salt to the water. She noticed the eggs at the bottom of the pot rose a little and began to float!

7. What was the experiment with oil?

Ayesha and Hamid got into an altercation while experimenting. After swirling it, Ayesha noticed that the oil had dissolved in the water. Hamid was adamantly opposed. “Look, the tiny yellow oil drops are still visible in the water,” he added. Ayesha sprayed two drops of oil on her tiffin box's lid. She then added two drops of water and two drops of sugar solution to the mix. She swung the lid open. Some drips slid down fast, but others remained behind. Read more about this chapter on Vedantu. The solution PDFs, revision material, or any study material provided by Vedantu is free of cost.

8. Why do some objects float while others sink in water?

Objects float or sink based on their density relative to water. If an object is less dense than water, it floats; if it is denser, it sinks.

9. What happens when you heat water during an experiment? 

Heating water can speed up the dissolving process of certain substances, like sugar, and change the behaviour of floating objects due to temperature changes affecting density and surface tension.

10. What are the practical applications of learning about water experiments in daily life?

Understanding water properties helps in everyday tasks like cooking, cleaning, and even in scientific and environmental studies, helping in better decision-making and problem-solving.
