Fibre to Fabric - Animal Fibres - Class 7 Science

Clothes are an important part of our lives. We wear clothes to cover us, to protect us from extreme weather condition and harmful insects and animals. Clothes worn by people also give information about their social, geographical and economic conditions. In this chapter we will learn about Natural fibres - silk and wool.

Fabric - The material that is used to make clothing is called fabric.
Fibre - Fibre is the basic material from which the fabric that you use is made. Fibres are spun into yarn. This yarn is then woven or knitted into a fabric.Fibres are classified into two types:

Natural Fibres

Synthetic Fibres

Silk

Properties of Silk:

Smooth texture and shiny look

One of the strongest fibres

One of the most expensive fabrics

Silk is produced from silkworms

History

According to a Chinese Legend, around 5000 years ago, the queen of Emperor Huang-ti was having tea in the garden when one yellow colored cocoon feel into her tea and strands of thread separated from it. She discovered the thread to be strong and started weaving it into fabric. Hence, started the silk industry of China. The Chinese kept the silk production a secret for many years while trading it with other civilizations and making huge profits. The route taken by the Chinese traders for the exchange of silk is known as silk route. Eventually silkworms were smuggled out of China and production of silk began in other countries. China till date remains the largest producer of silk in the world.

Making of Silk

Silk is made from cocoons which silkworms spin around themselves. A single thread of a cocoon can be upto 1600 metres long. The structure of silk is like protein. It is a poor conductor of heat and keeps the body warm in winter and cool in summer. The silk producing insects are actually the larvae of silk moth, Bombyx mori, are domesticated for large production of silk.

Raising silkworms

A silk moth lays about 200-300 eggs and dies. The eggs are kept in temperature range of 25 to 31 C in highly humid conditions, for a gestation period of about three weeks. After that worms hatch out. The worms are then kept in bamboo trays and fed on mulberry leaves. The worms are protected from harmful insects by wrapping the trays with cotton cloth. The worms are continuously fed, cleaned and moved for 2-3 weeks, after that worms stop feeding, each silkworm now secretes liquid silk from an opening under its mouth. Within 2-3 days, they form a full cocoon around themselves called pupa. The pupa undergoes many changes inside the cocoon. A few weeks later, the adult moth comes out of the cocoon.

Extracting thread

The cocoons are then put in pots of boiling water to kill the insect inside and to make the outer coating soft and loose. Then the threads are pulled out by a special technique called reeling of silk.

Dyeing and spinning

The silk after reeling is dyed in different colors and spun into yarn. Different qualities of silk are separated based on the length and texture of the yarn.

Weaving

The yarn is then woven into beautiful fabrics.

Wool

Sources and Making of wool

Animals like sheep, yak, llama, alpaca, few breeds of goats etc. bear fine hair on their bodies to keep them warm. These fibres are the source of wool for us. Sometimes, special breeds of sheep are chosen to produce offspring which have very fine hair. This is called selective breeding.

Rearing and breeding

Sheep are reared and bred in herds in the mountains and open areas. Sheep feed mostly on grass and leaves; they are also given grains, corns and oil cakes. When the sheep have a thick layer of hair on their body, they are ready for shaving.

Shearing

Shearing is the process of removing the hair coat from a sheep’s body. The hair coat is removed using mechanical razors. Shearing is mainly done in summer as the temperature is hot and sheep can live without the fur. The hair removed from the sheep’s body is called fleece.

Scouring

The fleece contains lot of grease, skin and other waste materials. It is thoroughly washed with soap or detergents or diluted acid solution so that the fleece is clear of waste. This is called scouring.

Sorting

After washing and drying, wool fibres are separated into different categories based on the texture. This process is known as sorting.

Removing of burr

Here the fluffy fibres known as burr are removed and the wool is washed again.

Dyeing

The wool is then dyed into different colors.

Making yarn

After dyeing, the wool is combed either manually or in machines. Lastly the fibres undergo spinning to form the woolen yarn. The woolen warn is then knitted into clothes.

Occupational Hazards

Exposure to chemical agents

Many chemicals are used during the process of making wool from fleece and silk from silkworm. The chemicals are primarily used during dyeing, bleaching, washing etc. such chemicals can pose health hazards like respiratory disorders, skin problems, allergies, cancer etc.

Exposure to dust and fibres

The exposure of workers to dust from materials like silk, wool, cotton, flax, jute during weaving, spinning, cutting, packaging can cause allergies, nasal or bladder cancer.

Nicholas Nye - Class 9 English

Nicholas Nye

By, Walter De La Marie

Thistle and darnell and dock grew there,
And a bush, in the corner, of may,
On the orchard wall I used to sprawl
In the blazing heat of the day;

Half asleep and half awake,
While the birds went twittering by,
And nobody there my lone to share
But Nicholas Nye.

Nicholas Nye was lean and gray,
Lame of leg and old,
More than a score of donkey’s years
He had been since he was foaled;
He munched the thistles, purple and spiked,
Would sometimes stoop and sigh,
And turn his head, as if he’d said,
'Poor Nicholas Nye!'

Alone with his shadow he’d drowse in the meadow,
Lazily swinging his tail,
At break of day he used to bray,-
Not much too hearty and hale;
But a wonderful gumption was under his skin,
And a clean calm light in his eye,
And once in a while; he’d smile:-
Would Nicholas Nye.

Seem to be smiling at me, he would,
From his bush in the corner, of may,-
Bony and ownerless, widowed and worn,
Knobble-kneed, lonely and gray;
And over the grass would seem to pass
‘Neath the deep dark blue of the sky,
Something much better than words between me
And Nicholas Nye.

But dusk would come in the apple boughs,
The green of the glow-worm shine,
The birds in nest would crouch to rest,
And home I’d trudge to mine;
And there, in the moonlight, dark with dew,
Asking not wherefore nor why,
Would brood like a ghost, and as still as a post,
Old Nicholas Nye

darnet    a type of grass commounly found growing in fields in Europe

The Tide Rises, the Tide Falls - Class 9 English

The Tide Rises, the Tide Falls

By, Henry Wadsworth Longfellow

The tide rises, the tide falls,
The twilight darkens, the curlew calls;
Along the sea-sands damp and brown
The traveller hastens towards the town,
    And the tide rises, the tide falls.

Darkness settles on roofs and walls,
But the sea, the sea in the darkness calls;
The little waves, with their soft, white hands,
Efface the footprints in the sands,
    And the tide rises, the tide falls.

The morning breaks; the steeds in their stalls
Stamp and neigh, as the hostler calls;
The day returns, but nevermore
Returns the traveller to the shore,
    And the tide rises, the tide falls.

Word meanings:

twilight    the light from the sky when the sun is below the horizon

curlew    a large wading bird

hastens    walking hurriedly

efface    to erase a mark from a surface

hostler    person employed to care for horses

The Sultanate: Important Developments:

Relationship between the ruler and the nobles

There was no rule of succession, anyone could become ruler, Turkish nobleman generally thought they were equal to the rulers as the rulers could not boast of a noble family name or the natural right to rule. The Chahalgani were a group of Turkish noblemen who enjoyed high administrative positions under Iltutmish. When Iltutmish died they tried to put a puppet on the throne who they could rule, Razia failed to suppress them and was killed. However Ghiyas-ud-din Balban succeeded in superssing the Chahalgani. He introduced rituals like Sijda and Paibos(lying on the ground and kissing the monarch’s feet) to show his superiority, he did not let the noble have their say and thus strengthened the monarchy.

Empire Building

During the early phase the Sultans only administered areas which were covered by the army known as garrison grounds. The materials (crops, money, and other material amenities) needed for such garrison grounds to grow were not available, so the Sultans conducted raids in areas where such materials were available. Ghiyas-ud-did Balban, Ala-ud-din Khalji and Muhammad bin Tughlaq solved these problems as they captured new areas. The Sultanate took the shape of Empire during the reign of Ala-ud-din Khalji and Muhammad bin Tughlaq.

Sultanate administration

Administration - First in the line of power was the Sultan. Under him were his Trusted Nobles (Turkish and Non-Turkish) and Ulama (religious people who advised the Sultan on judicial and religious matters)
Sulatanate Provinces Heads

The Sulatanate was divided into proviences called the iqtas. These were under the charge of walis or muftis.

The iqtas were further divided into shiqs and iqtas were under the charge of shiqdars.

The shiqs were further divided into parganas and parganas were under the charge of amils.

The parganas consisted of villages and these were headed by muqqaddams or headmen.

Patwaris and munifs were the other important officials, patwaris kept land records while the munifs looked after the collection of land revenue.

The samantas (landlord or chieftains) who ruled the hinterlands were brought under the direct control of the Sultan.

Sultanate in operation – The Tughlaqs

Muhammad Bin Tughlaq was a learned man well versed in religion and philosophy. He tried ways to strengthen the Sultanate most of which failed but his experiments were acknowledged. He transferred the capital of Delhi to Devgiri in the Deccan so that he could control the Southern territories. He ordered many trustworthy officers, Sufi saints to move to Devgiri which was then renamed Daulatabad. The road from Delhi to Daulatabad was long many people died on the way, though the expirement failed but it improved communication between North and South India.

Muhammad bin Tughlaq introduced the token currency as it was new system of monetization so it created confusion between traders and common people, people also started forging and the circulation of coins became more in market and the coins lost their value in market so the coin system was withdrawn.

He planned to raise a large army to attact the Mongols, so he raised taxes in the Doab region to feed his army but this region was in the grip of famine, so the peasants revolted there. His policy of appointing talented and efficient men to high offices failed due to the opposition of the nobles. Though his experiments failed still he is considered the most progressive Sultans of his time.

Decline of the Sultanate

The decline started in the Tughlaq Dynasty because of new kingdoms emerging in Malwa, Bengal, Gujarat and South India. It also further lost its authority due to the invasion of Timur. The South kingdoms had their own systems of rule while in the North the Rajputs and the Afghans emerged as important regional powers.

Motion and Time - Class 7 Science

Motion and Time

Important Points

Motion is always relative to a stationary point

To measure slow and fast motion, time is needed

SI unit of time is s(second)

Speed is the distance travelled by a body in a unit time.
SI unit of speed is m/s
Speed = Distance covered / Time taken

A uniform motion is when a body covers equal distance in equal intervals of time

A non-uniform motion is when a body covers unequal distances in equal intervals of time

Speed can be calculated from a distance-time graph by calculating its slope

The time period of a simple pendulum is the time taken to complete one oscillation
The time period of a simple pendulum does not depend upon the mass of the body

---

Simple Pendulum

A simple pendulum contains a small mass(called bob), suspended from a fixed point through a long string or rod
The bob moves freely under gravity
The motion of pendulum is called oscillatory motion
When the bob of pendulum moves from one point, goes on the opposite side and comes back to its original position, it is said to complete one oscillation
The time taken by the pendulum to complete one oscillation is called its time period
The time period is independent of the mass of the bob
The time period of a pendulum depends upon the length of the string from which the bob is suspended. Longer the string, greater is the time period

Units of Time

60 seconds(s) = 1 minute(min)
60 min = 1 hour(hr)
24 hrs = 1 day
30 days = 1 month
365 days = 1 year
12 months = 1 year
10 years = 1 decade
100 years = 1 century
1000 years = 1 millineum

Practice Time

Force - Class 9 Science

Important Points

Force - Force generally denotes push or pull. Force can :
i. produce motion
ii. stop motion
iii. change the direction of motion
iv. change the dimension in a body
The SI unit of Force is N

Newton's Laws of Motion

Newton's First Law of Motion - A body will continue in its state of rest or uniform motion in a straight line, unless compelled by some unbalance applied force to change its state of rest or uniform motion.

Newton's Second Law of Motion - The rate of change of momentum of a body is directly proportional to the applied unbalanced force and takes place in the same direction in which the force is applied.

Newton's Third Law of Motion - To every action there is an equal and opposite reaction.

Momentum - The force(impact) which a body possesses due to the combined effect of mass and velocity is called momentum. Momentum is denoted by p, where p = m*v where m-mass, v-velocity
The SI unit of momentum is kgms^-1

Mass - Mass is the measure of an object's inertia, more the mass more the inertia. It is a property of material , so it does not change with place.
The SI unit of mass is kg

Law of Conservation of Momentum - In a given system, the sum total of momentum is a constant quantity, provided no external force acts on the body or
In a given system, when two or more bodies interact and no external force acts on them, the total momentum of all bodies is conserved.

Inertia - Mass of a body is the measure of its inertia, i.e., the more the mass of a body, the more is its inertia.

Law of Inertia - The tendency of a body to continue in its state of rest or uniform motion in a straight line, unless some external unbalanced force is applied.

Inertia of rest - The tendency of a body at rest to remain at rest unless acted by an external force is called inertia of rest.

Inertia of motion - The tendency of a body in motion to remain in uniform motion in a straight line unless acted by an external force is called inertia of motion.

Questions and Answers

• Give two examples from everyday life where the Newton's third law of motion comes into place.
Ans. Example 1 - Rubber Ball rebounding: When we hit a rubber ball on the ground with some force(action), the ground reacts in opposite direction with an equal force and hence the rubber ball rebounds.
Example 2. Hurting of hand when we hammer a nail on a wodden plank - When we hit a nail with hammer on a wooden plank we apply a force then the nail reacts back with equal force on the hammer. As the hammer is held firmly in our hand, therefore, we feel hurt in our hand.


• Why does a boatman push the river bank backward with a long bamboo pole, on launching his boat in water? Explain.
Ans. It is based on Newton's third law of motion. When the boatman standing in the boat, pushes the river bank backward with a long bamboo pole, the surface of the bank reacts back and pushes the pole in the forward direction. As the pole is in the hands of the boatman, standing in the boat, the whole system moves in the forward direction.


• Why is it difficult to walk on marshy land? Explain.
Ans. It is based on Newton's third law of motion. When we push the marshy soil with our feet the soil yields. Thus, the reaction of the marshy soil is not as much as the action done on it. This makes it difficult to walk on marshy land.


• Why does a boatman push water backward with the oars, while rowing a boat? Explain.
Ans. It is based on Newton's third law of motion. When a boatman pushes water backward with the oars then water also exerts a reaction force which enables the boat to move forward.


• Why does a boatman tie his boat to a pillar, before allowing the passengers to step on the river bank? Explain.
Ans. When the passengers start disembarking, they push the floor of the boat backward with the feet. Now the boat is in water, and the water yields under the impact of this force. Thus, the boat starts sliding backward. To avoid the boat from sliding backward into water, the boatman ties his boat with a rope to a pillar before allowing passengers to disembark.


• Why do the birds flap their wings downward while taking a flight? Explain.
Ans. It is based on Newton's third law of motion. When the birds flap their wings downward they do action on the wind. The wind in turn reacts back and pushes the wings and hence the birds fly in the upward direction.


• Do the action and reaction act on the same body or different bodies? How are the action and reaction related to each other in :
  (a)magnitude and (b)direction? Do they act simultaneously or not?
Ans. Action and reaction act on two different bodies. Action and reaction are equal in magnitude but they act in opposite directions so there is simultaneous action and reaction.


• Why does a gun recoil backward when fired? Explain.
Ans. When the bullet under the impact of exploding gun powder moves out of the barrel from gun with a certain momentum, the gun, in order to conserve momentum, moves with the same momentum (momentum equal to that of bullet) in backward direction. So the net momentum is again zero. Thus, the gun recoils backward.


• Why does an inflated baloon rise up vertically for some distance, when punctured from below? Explain.
Ans. Initially, the balloon and the air in it, are in a state of rest and hence, have zero momentum. However, when the balloon is punctured from below, the air rushes out of it in downward direction with a certain momentum. Thus, in order to conserve momentum the balloon rises up vertically with the same momentum.


• Why do the pieces of cracker fall in all directions when it is burst? Explain.
Ans. When a cracker is not burst the momentum of the cracker is zero. When it is being burst the pieces move in all directions with certain momentum. However, if we add up the momentum of various pieces, the sum total of momentum will be zero.


• Why is it easier to stop a tennis ball than a cricket ball, moving at the same speed? Explain.
Ans. It is easier to stop a tennis ball than a cricket ball, moving at the same speed because the momentum of the cricket ball will be more compared to the tennis ball as the latter's mass is higher than the former's mass hence force required to stop the tennis ball will be less compared to the cricket ball.

The Vagabond - Class 7 English

Summary of the poem

R.L. Stevenson's poem "The Vagabond" is about the life of a vagabond(wanderer). The narrator wants to live a carefree life amidst the heaven, the land, the birds, the river. He does not yearn for wealth, friends, love, hope. He stresses repeatedly that he only wants the heaven above and the road below him, so that he can go places without worrying about the comforts of life. Nothing can reduce his spirit of wandering. He speaks of harsh conditions in autumn and winter but these also cannot deter his yearn to be on road.

3^rd Stanza

This stanza tells about the hardships of life staying outdoors in autumn and in winter. He says that let the leaves of autumn fall on him that represents the beginning of old age. In autumn, the field looks barren as the leaves have withered off trees. The birds around are silent and are no longer singing on the trees. The cold is severe in winter that blood freezes and fingers turn blue. The fields are snow laden. The fireside is the only place that can give some warmth and relief. However, the narrator further states that even such harsh conditions will not stop him from living in the open because all he years is freedom from anything else.
