Question 12.
Write various steps involved in making ghee from milk, what changes do you find, during this process?
Answer:
Production of ghee from milk involves various stages.

Stage 1: Milk changing to curd: (Curdling of milk): Milk is heated gently to boiling temperature and allowed to cool.
To the warm milk, a very small quantity of curd is added and stirred well.
The vessel is kept undisturbed for a few hours.
Then a white semi-solid mass appears in the vessel. It is curd.
Observed change : There is a slight difference in colour from milk to curd. Milk is slightly sweet and curd is slightly sour in taste.

Stage 2 : Butter from curd : Sufficient water is added to the curd. It is well churned.
Butter forms and floats over the liquid. The butter is hand-picked.
Observed change: Butter is a semi-solid mass. It separates from the butter milk.

Stage 3 : Butter to ghee : The butter is heated on a low flame for sometime. When we notice the smell of ghee we stop further heating. Ghee is formed.
Change observed : Semi solid butter is changed into ghee in liquid state which has a characteristic fragrance on heating.

Stage 4 : Separation of ghee from the residue : The mass is allowed to cool. Then it is filtered using a clean cloth. Residue is left over in the cloth. Ghee is collected in the vessel.
All the changes involved in making ghee from milk are permanent changes. They are all irreversible

TS Board 6th Class Science Guide Telangana 9th Lesson Plants: Parts and Functions Textbook Questions and Answers.

TS 6th Class Science 9th Lesson Questions and Answers Telangana – Plants: Parts and Functions

Question 1.
What are the important parts of a plant ?
Answer:
Stem (trunk), branches, leaves, twigs (small branches) and roots are the important parts of a plant.

Question 2.
How will you tell which part of a plant is the stem and which is the root?
Answer:

• We can identify stem and root parts by the following way.
• The part which bears branches, leaves, flowers and flower buds is called stem.
• The stem bears entire aerial part of the plant.
• The part of the plant which helps in anchoring the plant body to the soil is called root.
• Roots absorb water and minerals from the soil.

Question 3.
Collect any plant from your surroundings. Draw its root structure. What can you say about its root system?
(Or)
Draw a neat labelled diagram of root system of tridax plant.
Answer:

• The root system in the collected plant exhibits tap root system
• In this plant, the main root becomes thick. This main root is called tap root.
• From the main root, small sideward roots are formed. These small roots are called lateral roots.

Question 4.
John has no place in his house but he wants to plant vegetables like tomato in his house. Suggest him different ways to do so.
Answer:

• If John’s house is with reinforced concrete cement roof (slab), there are alternative methods of harvesting vegetable plants like tomato.
• The following methods can be followed by John.
• By introducing the small height wooden pots (or rectangular tubs) along with collected humus or vermicompost.
• By preparing cement tubs is also a possible method of growing tomato plantations. The cement tubs are to be filled with humus or compost.
• If John’s house is not with RCC roof, he has to do the following.
• Hanging the potted tomato plants outside his house to allow them for better aeration. This also helps him to grow the plants.

Question 5.
What will happen if a plant doesn’t have any leaves?
Answer:

• Leaves are the essential food factories of plants. They synthesize food for whole plant by the process of photosynthesis.
• Appearance and development of more leaves lead to synthesis of more food in the plant.
• If number of leaves decrease in the plant, there will be a decrease in food production.
• Except in few plants, leaves are the only prime sources for synthesis of food.
• Therefore, if a plant doesn’t have any leaves it will die soon.

Question 6.
How does the stem help the plant?
Answer:
Functions of Stem:

• Gives support to branches, leaves and fruits.
• Establishes connection between roots and leaves.
• Supplies water and minerals dissolved in water from roots to leaves, flowers and fruits.
• In young plants, the stem also performs photosynthesis.
• In some plants, stem stores food material.

Question 7.
What type of venation is found in the leaves of plants with fibrous roots?
Answer:
Parallel venation is found in the leaves of plants like grass, coconut, date palm etc. These plants possess fibrous roots.

Question 8.
If the leaves have reticulate venation, what would be the type of root?
Answer:
Naturally, the plants which have tap root system possess reticulate venation.
The veins and veinlets divide into small branches. Eg: Datura (Ummetta), Guava.

Question 9.
Explain the various parts of a plant with the help of a diagram.

Answer:
The plant diagram that is drawn above shows the following important parts.

• Stem: Stem is the main part of the plant. It supports the entire aerial part of the plant.
• Branches: Stem of the plant divides into so many branches. Branches are the other main parts of the plant. They bear leaves, flowers, buds and fruits.
• Leaves: Leaves are the main sources of the plant. They prepare food for the plant. They are called food factories of the plant.
• Flowers: Flowers are the reproductive parts of the plant. They develop into fruits.
• Stem tp: This is the growing region of the plant.
• Roots: Roots are the anchors which fix the plant firmly to the soil. These provide water and minerals to other parts of the plant.

Question 10.
Explain the parts of a leaf with the help of a diagram.

Answer:
There are five important parts in a leaf. They are.
1. Leaf base 2. Petiole 3. Lamina or leaf blade 4. Midrib 5. Veins.

1. Leaf base: This is the lower part of the leaf where the leaf attaches to the stem near the node.
2. Petiole: The stem – like part of the leaf that joins the leaf blade to the stem is called petiole.
3. Lamina or leaf blade : This is the green, expanded portion of the leaf.
4. Veins : Many ridged branched structures that spread on the lamina are called veins. They spread as veinlets.
5. Midrib : The long vein present in the middle of the lamina is called as Midrib.

Question 11.
How can you show that plants absorb water through their roots?
(Or)
Roots of plant absorb water and minerals that are present in the soil. How can you prove this with experiment?
Answer:
Aim : To show that the plants absorb water through their roots.
Apparatus : Two glass tumblers, two plants having soft stems, ink bottle, water or ink filler.
Procedure : Two glass tumblers are taken and filled with water. Two plants having soft stems, along with their roots are placed in the tumblers. Few drops of red ink are added in one of the tumblers. Then the water is changed into red colour. Both the tumblers are undisturbed for 2- 3 hours.
Observation : Red spots are seen in the stem which is in red coloured water. No spots are seen in other plant which is in colourless water.
Inference: It is concluded that roots help in taking up of water. The coloured water enters the stem through roots. Roots have the capacity of absorbing minerals and water from the soil.
Result : Plants absorb water through their roots.

Question 12.
Rajani said “Respiration takes place in leaves”. Is she correct? How can you support this statement?
Answer:
Plants respire as animals perform with special organs. But we cannot recognize external respiration (exhalation and inhalation). Respiring of gases is done through stomata which appear on the leaf surface and lenticels present on the bark of the stem and root surfaces. The mechanism of cellular respiration or internal respiration is very recognisable as it is seen in the animals.

Question 13.
Collect the leaves of various plants. Prepare a herbarium. Write a brief report on their shapes, size and venation.
Answer:
Aim of the project: To collect various plant leaves to find out their shapes, sizes and venation.
There are two types of leaves based on their shape and venation. Based on the shapes, they are two types.

• Simple type
• Compound type.

There are two types of venation

• Reticulate venation
• Parallel venation.

Tabulation of information:

Question 14.
Prepare a greeting card with dry leaves.
Answer:
Aim : To prepare a greeting card with dry leaves.
Requirement: Banyan tree leaf, chart with accurate length and width (6 x 4 inches)
Procedure:

• The collected banyan leaf is soaked in the lime water for one or two days.
• As a result, all the green part disappears.
• Only veins and veinlets are left in the leaf. It looks like a skeleton structure of the leaf.
• Then, gently a picture is drawn on that leaf.
• Painted leaf is pasted on the chart piece with specific length and width.
• Finally, the beautiful greeting card is ready.

Question 15.
Your teacher suggested not to harm other plants when you collect plants for observation. Why did she suggest so?
Answer:
Her suggestion is reasonable. Because,

• to observe the plant parts, it is not needed to pluck the parts from the plant.
• if we continue to pick up the plants, removing from the soil, their population will gradually decrease.
• decreasing plant population is dangerous to the earth and other organisms.
• plants give us oxygen and take carbondioxide from us.
• they provide plenty of food to the man.
• plants stop the clouds and help in giving rains. Due to all the above reasons our teacher suggested us to think of destructing plants for research work.

Question 16.
Observe a plant which has healthy green leaves and beautiful flowers. Write your feeling about the plant in your notebook.
Answer:

• When we see a plant with lush green coloured leaves and beautiful flowers, we wonder at the glance of such plant.
• Naturally, we like to protect beautiful plantations.
• Our feelings make a plan to conserve the living organisms, to sustain the better nature inhalance.
• The beauty of the flowers makes us relax and its fragrance gives us aroma.
• The green colour of the leaves gives us good scenery and good visible colour. Green colour is quite healthy for eyes.
• We also feel to grow the plants having green colour and beautiful flowers in our surroundings.

TS 6th Class Science 9th Lesson Notes Plants: Parts and Functions

• The important parts of a plant are roots, stems and leaves.
• Tap root system and fibrous root system are two types of root systems seen in plants.

• The stem carries the water absorbed by the roots to different parts of the plant.
• Leaf base, petiole and lamina are all parts of a leaf.
• Tap root : In some plants, the main root becomes thick and has thin rootlets. This main root is known as ‘tap root’ and the rootlets are called lateral roots.
• Fibrous root : Hair like roots of the plants are called fibrous root.
• Leaf : Leaves are involved in preparing food. They also help in exchange of gases and transpiration.
• Petiole : The stalk of the leaf attached to stem.
• Lamina : The green expanded portion of leaf.
• Stomata : The bean shaped part that you see in the leaf acts like our nose. These are called ‘stomata’.
• Reticulate venation : Branched appearence of veins on the leaf.
• Parallel venation : Parallel appearence of veins on the leaf.

Question 12.
Collect news items about handloom workers and cotton growers. Analyse one news item in your own way.
Answer:
Handloom workers – the life is miserable
March 16- Pochampalli : Hand loom workers in the state are facing lot of burdens. Since they are accustomed only to handloorn industry, they are not able to find any other suitable livelihood to feed the family. Middlemen make selfish business by cheating the labourers at work places.

Handloom workers spend their whole time at the work. But getting wages is very less. It is not enough to fulfill the family needs. Interestingly, retail business men also see profit as middlemen bring lot of work through unauthorised marketing.

The Umnin of handloom workers urged the government to take necessary action in favour of hiking their daily wages. They also insisted to see transparent business which brings at least sharing in the profit from the handloom industry owners.

Time should help the cotton growers:

April 17 – Gadwal : Cotton growers have had bitter experiences due to unfavourahie weather conditions and lack of support from the government. Middle men and some brokers cheat the farmers by not giving the profitable price for the harvested cotton. Unfair activities to earn the money becomes main motto of raw material buyers.

They huy the harvested crop at low cost, hut they sell it to the price which is two times more than the price paid to farmers. In this way the farmers are cheated. Many times, farmers requested the government to help them.

Analysis on the report: If handloom department encourages the workers they will renew their life. Middle men dealing should he abolished which will bring the profit up in favour of labourers. Government should help the workers by providing facilities such as free education to the children, free health insurance scheme etc.

Government should take authentic steps to do business by the workers through which they rejuvenate their livelihood. The handloom weaving is an old tradition. The tradition and techniques used by weavers produce finest quality textiles which machine made textiles can not give. Yet, the handloom sector is facing a lot of problems. The government efforts to restructure handlooms are to be appreciated.

Question 13.

TS Board Telangana SCERT Class 6 Science Solutions 7th Lesson Separation of Substances Textbook Questions and Answers.

TS 6th Class Science 7th Lesson Questions and Answers Telangana – Separation of Substances

Question 1.
Is it possible to separate sugar mixed with wheat flour? If yes, how will you do it? If powdered sugar is mixed with wheatflour, how do you separate them?
Answer:

• Yes, it is possible to separate sugar mixed with wheat flour.
• They can be separated by sieving, using a sieve with a proper pore – size. The flour particles are very fine and pass through the holes of the sieve. The sugar particles being large are left on the sieve.
• The mixture containing powdered sugar and wheat flour is dissolved in water. Sugar only dissolves. Flour does not dissolve. They are separated by filtration, using a filter paper. Flour remains in the filter paper. It is dried. We get the flour. The sugar solution is slowly evaporated. Water evaporates. Sugar is left over in the dish. Thus, flour and sugar are separated.

Question 2.
Why is hand picking necessary after win nowing?
Answer:

• Some undesirable substances such as pieces of stones remain in rice or dal. After winnowing also they can be separated by hand picking.
• This is possible because the particles of the undesirable substances are different from the food grains in colour, shape and size and easily identified with eye.
• This method is convenient when the undesirable components are present in small quantities.

Question 3.
Srikar accidentally mixed mustard seeds with rice and salt. How can he separate them?
Answer:
The separation is done in 3 steps:

• Mustard seeds are separated by sieving.
• The mixture containing rice and salt is shaken with water, salt dissolves, leaving rice. They are separated by filtration using a filter paper. Rice collects on the filter paper.
• Now the salt solution is carefully evaporated by crystallization process. Then water escapes, leaving the salt in the dish. Thus mustard seeds, rice and salt are separated from their mixture.

Question 4.
Which separation process is used when one component is in a mixture:
a. Heavier than the other?
Answer: Winnowing

b. Bigger than the other?
Answer: Hand picking

c. Different shape and colour from the other?
Answer: Hand picking

d. One is soluble in water and the other is not?
Answer:  Filtration and then crystallization.

e. One floats and the other sinks in water?
Answer: Decantation using a sieve. The floating substance collects in the sieve. The heavier substance remains in the container.

Question 5.
Visit a nearby dairy and report about the processes used to separate cream from milk.
Answer:

• Certain amount of milk is allowed into a container.
• The container’s plug (spigot) is closed tightly at the bottom of container.
• It is undisturbed for 24 hours.
• Then plug is opened. It is observed that the skimmed milk (butter less milk) comes out, leaving the creamlime floating at the top.
• Once the milk layer becomes thik at the end, it is separated and collected from the container.

Question 6.
Divya suggested some methods to separate mixtures given below. Are they correct? Find whether they are possible or not. Give reasons.
a. Pure water can be obtained from seawater by the process of filtration.
Answer:
Not possible.
Reason: Sea water contains many dissolved salts. These salts cannot be separated from water by filtration.

b. Cheese is removed from curdled milk by the process of decantation.
Answer:
Possible.
Reason: When milk curdles, it separates into solid and liquid parts. The solid part is separated from the liquid part, by decantation.

c. Separation of sugar from tea can be done by filtration.
Answer:
Not possible.
Reason: Sugar dissolves in tea. So it cannot be separated by filtration.

Question 10.
Draw a picture of the article used for separation of mixture in your house.
Answer:

Question 11.
Kiran observed his father separating husk and grains by winnowing method in the field and appreciated how wind flow helped in separation. On evaporation salt is formed from sea water. Isn’t it? How would you appreciate this process?
Answer:
1. Kiran’s father stood on a high platform and allowed the mixture of grain and husk to drop slowly from the flat pan. The wind carried away the husk forward. The grains fell vertically downward. Thus a separate heap of grain is formed.

2. Sea water is allowed to stand in shallow pits. Water gets heated by sunlight and slowly turns into water vapour and escapes out. (Process is called evaporation). In a few days, the water evaporates completely leaving behind solid salts (a mixture of salts). Common salt is thus obtained from this mixture of salts by further purification.

TS 6th Class Science 7th Lesson Notes Separation of Substances

• We separate the components of mixtures for different purposes in our daily life.
• Items like tea, lemon juice, soil etc., contain more than one substance. So they are called, mixtures.
• There are natural mixtures, as well as man-made mixtures.
• We make use of several properties of the materials for separating the desired items from the mixture.
• An Example:
  When a mixture of water, sand and mud is allowed to remain undisturbed for sometime, sand along with the mud settles down at the bottom of the container. These are called, sediments. This process of separation of sand and mud from water is called sedimentation.
• Mixture: Combination of more than one substance is called a mixture.
• Separation: We follow different methods to separate substances from a mixture.
• Hand picking: The substances which are carefully chosen and separated by hand from the mixture is called hand picking.
• Winnowing: The method of separating the heavier material from the lighter material. Separating the substances in the mixture by wind or by blowing air is called winnowing.
• Sedimentation: The solid material that settles at the bottom of a liquid is called a sediment’, and the process is called sedimentation.
• Decantation: The process of separation of clear upper liquid from the sediment is called decantation.
• Sieving: It is a method used to separate fine particles from large particles in a mixture using sieve.
• Filtration: It is a process of filtering a substance.
• Crystallization: Crystallization is a process used to separate dissolved solid substances from a liquid.
• Distillation: The process used to remove impurities from water is called distillation.
• Sublimation : The process in which a substance changes directly from solid to gaseous form and vice-versa is called sublimation.
• Chromatography : The process of separating the components of mixture, by passing it through a material.

TS 6th Class Science 6th Lesson Questions and Answers Telangana – Habitat

Question 1.
What is a habitat?
Answer:
Habitat is a dwelling place for plants and animals that gives them optimum conditions of life.

Question 2.
Name some plants and animals that live in terrestrial habitat.
Answer:
Examples of terrestrial plants: Neem, mango, jasmine, guava, apple, orange, lemon tree, grapes etc.
Terrestrial animals : Tiger, lion, sheep, cow, cat, dog, donkey, monkey etc.

Question 3.
Why can’t fish live on land?
Answer:
Body of the fish is adjusted to water habitat. Living habits of fish are only helpful to the water life. The respiratory organs of fish are ‘gills’ which are helpful to take oxygen dissolved in water, It can’t take oxygen in the air with its gills. So fish cannot live on land.

Question 4.
“Animal skin is a habitat for some organisms.” What do you understand by this statement?
Answer:

• We often find some microbial organisms and insects on animal bodies and on human bodies. (Man is also an animal scientifically)
• So, animal skin is the habitat for some organisms.

Question 5.
Identify the habitat in which the following live. More than one organism may be present in one habitat.
Our intestine, pond margin, kitchen, garden, tree, underground, grass
(or)
Write about different habitats around us.
Answer:

• Our intestine : Bacteria, hookworms

• Underground : Snakes, rats, earthworms, crabs etc.
• Grass : Bacteria, grasshoppers etc.

Question 6.
What happens if a habitat is disturbed or destroyed?
(or)
What will happen If we do not protect the habitats of the plants and animals?
Answer:
If a habitat is disturbed or destroyed, the living world in that habitat is also disturbed. Destroying particular habitat affects balance in the habitat. Plants and animals living in that habitat may suffer from all the living problems.

Pollution or natural problems will be seen in the habitat. Animals may suffer from lack of food, oxygen and shelter. Plants lose their capacity of getting necessary things for their lives. If these organisms are harmed, then it is indirectly harming ourselves. It disturbs our quality and better life.

Question 7.
Why do some animals change their habitat ?
Answer:
Animals change their habitat for the following reasons.

• To search for suitable residing area.
• To obtain food material from the new habitat.
• To protect their lives from the enemies.
• To save lives from the natural disasters like cyclones, earth quakes etc.
• Animals change their habitat to live with their same animal races also.

Question 8.
Observe a spider in its web and write how a spider shares its habitat.
Answer:

• Spider is a unique insect in the animal kingdom.
• Naturally it lives in undisturbed areas like corners of the houses, house roofs, and in old buildings.
• To make a shelter it releases saliva in the form of threads. The thread like structures released by a spider form a web.
• At the centre of the web the spider performs some of its activities.
• The web is used for protecting the spider from enemies, helps in taking rest and to capture its prey.

Note : Students have to design the above diagram based on their school and its surroundings.

Question 15.
Prepare an article to deliver a speech in Literary Association meeting on Animals also have a right to live”.
Answer:
Speech: Respected class teacher and dear friends ! Today, I want to share my feelings about the animals’ right to live. Man is a social animal along with other animals on this planet. Man should love other animals as he loves himself. We feel that we have a right to live like anything at any cost.

Then why shouldn’t other animals have the same rights as we have. It is a must to see the animals enjoy their rights to live along with us.

• Animals are partners of our habitat. Their also have a right to live.
• We people are encroaching on their habitats.
• If we cut a tree, birds that live on it lose their nests and fall in danger.
• We often sec dogs, cows, monkeys suffrring from lack of food and shelter.

What should we do?:
Every one should discriminately think about other animals and their rights to live in nature. To maintain perfect balance of the nature we should see that all the creatures must be protected from dangers.

BLUE CROSS is a voluntary organisation to work for animal rights and protection. With such voluntary organisation we should get awareness on conserving the animals and their lives.

One who loves other creatures knows the true value of love. Hope you agree with me. Thank you for listening to my speech.

Question 13.
We use so many wooden items in our daily life. Is it good to use wood? What happens by excessive use of it? What is the reason? Is there any alternative for this?
Answer:
Uses of wood:

• Indeed the things made of wood are environment eco – friendly products.
• Wooden items do not caust harm to the environment.
• To make the items with wood, we should depend on forests and domestic plants.

Demerits of cuffing trees:

• Cutting trees for wooden items severely affects the decrease in forests and all the plantations is called deforestation.
• Deforestation leads to imbalance in nature and there will be a decrease in rainfall.
• Oxygen in the atmosphere decreases.
• Deforestation causes topmost soil erosion. Thus in turn it results in losing of soil fertility. Due to soil erosion we lose food grain harvestation.

Alternative steps to avoid cutting trees for wooden items:

• One way is to grow the wood giving plants in the waste land areas with the help of our society.
• The wooden furniture, once we purchase them from the shop, should be used them without damage.
• We should not cut down non-wood giving trees along with wood giving plants unnecessarily.
• We have to find a solution to convert any waste and already used material into wooden like furniture.

TS Board Telangana SCERT Class 6 Science Solutions 3rd Lesson Rain: Where Does it Come From? Textbook Questions and Answers.

TS 6th Class Science 3rd Lesson Questions and Answers Telangana – Rain: Where Does it Come From?

Question 1.
How are clouds formed ? Explain.
Answer:

• On a sunny day, the sun heats up the ground as well as the water in seas, oceans, rivers, ponds etc. This water converts into water vapour by the process of evaporation.
• Evaporation is the process of water changing into water vapour.
• Evaporation is a natural process which takes place on the earth.
• Water evaporates continuously from the surfaces of water bodies like seas, oceans, rivers, ponds etc., and changes into water vapour due to the heat supplied by sunlight.
• The water vapour entered into air through the process of evaporation forms clouds in the sky.

Question 2.
How does the rain water reach from clouds to rivers or oceans ?
(Or)
Describe the relationship between oceans and rains.
Answer:

• The water in the water bodies gets heated up and converts into water vapour by the process of evaporation.
• When water vapour reaches higher levels it condenses due to contact with cool air and forms water droplets.
• These droplets remain floating in air at higher levels of the atmosphere and appear as clouds.

Question 3.
When do clouds become cool ?
(Or)
Explain the changes that take place in clouds before it rain.
(Or)
How do you imagine that it is likely to rain ?
(Or)
Water vapour converts into clouds. How clouds turn into rain ?
(Or)
Krishnaveni said, “The raining takes place from clouds”. What are the observations you make at the time of raining?
Answer:

• Winds bring the clouds from the sea to the land. Clouds are nothing but evaporated water.
• The colder air in the upper layers of the atmosphere cools the clouds.
• The clouds moving in air are generally at higher levels.
• Sometimes the cool breeze coming along with air makes the clouds cooler.
• These cool clouds bring rain.

Question 4.
Explain the relationship between the heat of sun and evaporation.
Answer:

• On a warm day, the sun heats the ground as well as the water in the water bodies.
• This water converts into water vapour by the process of evaporation.
• More the sun heats up the water from water bodies, the more evaporation of water occurs.
• The formation of clouds depends on the amount of water that evaporates due to sun heat.

Question 5.
Why do we experience cloud like smoke near our mouth while we speak during the winter season?Answer:

• In winter, the air in our atmosphere is very cool as compared to the air coming out from our mouth.
• Water vapour present in the air coming out from our mouth gets cooled suddenly to form very tiny droplets.
• These tiny droplets concentrated in a limited area, appear like smoke or a small cloud near our mouth.

Question 6.
Correct the given sentence if necessary.
“If the size of water drops decreases in the clouds, they can no longer hold the water drops.”
Answer:

• The given sentence is not applicable for the characteristic feature of the appearance of the clouds.
• When water vapour reaches higher levels it condenses due to contact with cool air and forms small drops or water droplets.
• These tiny droplets remain floating in air at higher levels of the atmosphere and appear as clouds.
• Therefore if the size of water drops decreases in the clouds, they can hold water drops.

Question 7.
Which of the following days is more suitable for drying of washed clothes? Explain why.
a. Windy day b. Cloudy day
Answer:

• Windy day is more suitable than the cloudy day for drying of washed clothes.
• The rate of evaporation increases with the wind flow.
• Cloudy atmosphere has less capacity of evaporating water into vapour than windy atmosphere. The evaporation will be slow.
• Clothes dry faster in windy atmosphere, and slower in cloudy regions.

Question 8.
Which of the following statements are right (Or) wrong?
a. Evaporation takes place quickly when more heat is supplied.
b. For condensation of water vapour, it should be cooled.
c. Water vapour is obtained from water by its evaporation.
Answer:
The three given statements are true to their nature.
a. Evaporation takes place quickly when more heat is supplied.
b. When water vapour gets cooled, it turns into water. Cool air converts water vapour into water droplets which in turn finally into water by the process of condensation.
c. The process of changing of water into water vapour is called evaporation.

The beauty of seven colours of crayon
I am smiling at nature that goes on
Greet me, I greet you forever and ever
See me, I see you and leave you never
Oh God ! What a great creation you make
For the leisure of creatures and their sake

Question 11.
Clouds once seen at a particular point, may not be there after sometime? Why?
Answer:

• The clouds once seen at a particular point may not be there after sometime.
• This is because of the movement of clouds from high pressure areas to lower pressure areas.
• Pressure influences the movement of clouds.
• The difference in pressures in two different areas leads to the movement of air.
• Thus the clouds also move along with air from high pressure area to low pressure area.

Question 12.
Revanth blew air from his mouth onto the mirror while he was getting ready togo to school. He observed that the image in the mirror was not clear. Do you have any doubts to raise in this situation ? Prepare questions on your doubts.
Answer:
Revanth blew air from his mouth onto the mirror. He confused at the appearance of moist layer on the mirror. He doubted and may have questioned himself in the following way.

• What is the reason for the formation of some moist layer on the mirror?
• Why did the mirror become unclear after blowing air on it by mouth?
• What comes out of my mouth while blowing?
• Does it happen even for other animals also?

Question 13.
If it is raining in a village you don’t find rain another village. Why do you think it is happening so?
Answer:

• Often we see that there may be rain in some area, where it may not be in its adjacent areas.
• This is because of condensation of clouds due cool air which affects on them in the specific area.
• Occurance of winds won’t be same in all the areas. Pressure influences on the presence of air.
• Clouds along with winds move from high pressure area to low pressure area at which cool air occurs.
• That why rain is seen only in some areas, where we can’t see it in its adjacent areas.

Question 14.
If condensation fails to occur in nature what happens?
Answer:
If there is no occurance of condensation in the water, water cycle stops due to lack of rains.
If there are no rains water sources will not be filled with water.
Even ground water level decreases.
Low percentage of water levels in the natural water bodies cause damage to the living kingdom, thus it finally lead to destruction of nature.
Hence condensation process is very essential in the water cycle.

Question 15.
Why does the driver of a vehicle wipe the glass inside, even if the wiper is working on outer surface of the glass when he drives in rain?
Answer:

• The driver wipes the glass inside, even wiper is working on outer surface of the glass when he drives in rain.
• Because of the natural process called condensation rain that falls on the glass of the cabin cools its surface.
• Air inside the drivers cabin contains water vapour which is warmer than the outside surface of the glass.
• Due to the cold glass, air close to its inner surface will also become cooler.
• This changes the water vapour in the air of the inner surface of the glass into water and forms small drops on the inner surface.

Similarly predict and find out in which direction you keep your head while sleeping at night, the directions you face while you are reading, eating etc.
Answer:
1. Naturally any architecture professional designs the house blue print in East – West direction. This is because of one reason by allowing morning sun-rays into the house and better ventilation.

2. Compass is used to find out the specific direction of its construction. I clearly found that it is in East-West direction.

3. Head is kept either in East-West (or) West-East direction while sleeping. This is to avoid North-South direction of the magnetic influence.

4. Our elders advise us to sit for study in East-West direction, we avoid sitting North – South direction. We do the same thing while taking meals. For the above reasons we avoid North-South direction of the magnetic influence.

Question 7.
Prepare a toy using magnets and write the procedure of preparation briefly.
Answer:
Aim : To prepare a toy using magnets.
Apparatus : Two bar magnets, a toy (car or doll)

Procedure:

Question 10.
Sometimes people use magnets to keep the doors open and sometimes to close the doors firmly. Think and say how it is possible and how we should arrange the magnets in each case.
(or)
Magnets are used in closing and opening of doors and windows. How is it possible ? Think and write.
Answer:

• It is possible to close and open the doors firmly.
• The facility of this is based on the magnetic property of two magnets.
• The magnetic property says unlike poles of magnets attract, like poles of magnets repel.
• We can do this by changing the direction of table magnet. The suspended one also changes its direction.

Application of Magnetic property to the doors:

• When doors are opened firmly, it is because of placing two magnets facing each other with like poles in two doors. This results in firm opening of doors.
• When doors are closed firmly, it is because of placing of two magnets facing each other with unlike poles in two doors. This results in firm closing of the doors.

Question 11.
Does the Earth behave as a magnet? How do you prove it?
Answer:
Aim : To prove the magnetic behaviour of the Earth.
Apparatus : Two bar magnets, thread, table etc.

Procedure:

• A bar magnet is placed on the table. Another bar magnet is suspended very close to the first one kept on the table.
• It is observed that the north pole of the suspended bar magnet points towards the south pole of the magnet placed on the table.
• The south pole of the suspended bar magnet points towards the north pole of the bar magnet kept on the table.
• Later the first bar magnet is removed from the table. But the suspended magnet is still hanging on the table.

Observation:

• The suspended magnet comes to rest in the North-South direction.
• It is said that there is some magnet below the suspended one, which makes it to come to rest in that particular direction.

Result : It is evident that the earth possesses magnetic property which acts upon the suspended bar magnet.
Inference : The earth exhibits greater magnetic property with north and south poles.

Question 12.
If you have two similar bars, one a magnet and another a piece of iron, can you find out which one of these is a magnet? Explain the process.
Answer:

• The substance which exhibits magnetic property attracts the other magnetic material. This occurs in case of magnet.
• Because it attracts the other bar, which is iron.
• When both the bars are kept closely, the true magnet bar attracts the iron bar.
• On the other hand iron bar doesnt show attractive property on true magnet.
• By the following way we can recognise true magnet and magnetic substance.

Question 13.
Teacher said that earth is a magnet. But Sree Vidya has some doubts and she asked her teacher some questions. What may be the questions?
Answer:

• If Earth possesses magnetic property why don’t all the iron material attract towards any one of the poles of the Earth?
• How can we prove the magnetic property of the Earth?
• What is the advantage of magnetic property of Earth for living kind?
• Where are south and north poles of Earth’s magnet?

Question 14.
Surya was wonder struck to know that Earth is a big magnet and appreciated efforts of scientists to discover this. Do you notice any such things In magnets to appreciate? Explain.
Answer:

• Isaac Newton discovered that the Earth possesses magnetic property. He proved it by observing fall of apple from the plant.
• Indeed we should appreciate the great power of magnetism.
• Because of the magnetic property, the Earth revolves round the sun in the name of gravitational force.
• The moon revolves round the Earth with specific magnetic property influenced by Earth.
• In favour of living kind the earth sustains all the organisms.
• Due to above reasons we can appreciate the magnets and the concept of magnetism which exist in the nature.

Question 15.
Kiran wants to prepare a toy using some magnets to make people under stand the slogan “Reject bad food and accept only good food.” Can you help him to prepare the toy? If yes, how?
Answer:
1. Applying the magnetic property for making a toy magnet to conduct the programme is interesting.

2. The junk food box is placed on one side of the table. Good food box is kept on the other side.

3. Each item of the junk food with bar magnet facing its specific pole is arranged. Likewise to the good food items having magnet facing its specific pole.

4. Moving the toy magnet in front of junk food, keeps away from them. Because of the facing pole of the toy magnet is as same as pole of the junk food items.

5. Moving the toy magnet in front of the good food items, attract them,because of unlike poles of the food items magnet and toy magnet.We should emphasise the magnetic property of the two bar magnets in our day to day life. To conduct an awareness programme on food items, toy magnet game will be very interesting.
