potato potatoes

hero heroes

mosquito mosquitoes

However, some nouns that end with –o form their plural in the normal way – piano- pianos,

studio- studios, photo- photos.

If a noun ends with a –y and the –y has a consonant before it, its plural is formed by

changing the –y into –ies. Eg:

You must remember that the plural of ‘man-servant’ is ‘men-servants’.

Scissors, spectacles, shorts, trousers, clothes (stitched) are used in the plural form.

Eg: Her spectacles are new. (Plural verb –are)

Mathematics, news, politics and innings appear to be plural but they are used as

singular nouns. Eg:

Abstract nouns like love, anger, beauty are not countable and have no plural form.

Names of materials or substances like copper, wood, paper, stone, iron (known as

material nouns) are not countable. They are used only in the singular form.

Eg: Gold is precious.

We say – The child is collecting stones. (‘stones’ implies pieces of stone)

It is incorrect to say – This cottage is made of stones. We would say - This cottage is

made of stone.

Class 6 S.St. Worksheet – 5 (History& Civics)

Chapter – 2 The River Valley Civilisations

(Part II Summary)

Egyptian Civilisation

Egypt, often called the ‘Gift of the Nile’, was the seat of another great Bronze Age

civilisation. The annual floods of the river Nile provided fertile land and water for

irrigation. Hence, the Nile valley became a seat of civilisation in spite of being

surrounded by deserts. The history of ancient Egypt between 3000 BC and 1000 BC can

be divided into three phases- the Old kingdom, the Middle kingdom and the New

kingdom.

Source Materials – The literary source materials are in the form of hieroglyphic writings

on papyrus and engravings on pillars, walls of tombs and palaces.

The archaeological source materials include the following –

Building structures like pyramids, temples, pillars, canals and ditches

Statues of various mythological figures and rulers.

Artefacts and other goods like bronze tools, weapons, ivory and stone.

Town Planning –

In the city of Amarna in ancient Egypt, a royal road ran parallel to the river Nile.

It connected the northern and the central parts of the city.

The luxurious stone residences of the royalty and high officials were situated in

the north.

The king’s official residence, temples, administrative buildings, storehouses and

clusters of mud-brick houses of ordinary people were situated in the centre.

Social Life

The king was regarded as a god, and his will was law.

He was given the title pharaoh. He was at the top of the

social ladder, followed by the priests and officials.

The craftsmen and farmers came next, and the

slaves occupied the lowest rung.

Women could own and inherit property.

Some women, like Queen Hatshepsut,

even ascended the throne. Stone bust of a pharaoh

Occupations

Agriculture was the chief occupation of the people. Dogs, goats, donkeys, pigs,

camels, oxen and horses were domesticated.

The Egyptians were skilled at weaving, stone working, ivory making, glass

making and carpentry.

Trade seems to have been carried on by land and sea, and along the Nile as well.

Religion

The sun god Re was the most important Egyptian god. The moon, the floods

and other natural phenomena were also worshipped. There were some local

gods too, represented by the symbols of certain animals like the crocodile,

jackal and cow.

The Egyptians believed in life after death. Accordingly, they embalmed dead

bodies by applying salt and chemicals on dead bodies to preserve them. These

embalmed bodies are called mummies. The coffins were buried in tombs,

along with the personal belongings of the dead.Fabulous riches were found in

the tomb of the pharaoh Tutankhamun.

Script - The Egyptian script is called hieroglyphic, meaning ‘sacred carving’. The

Egyptians wrote with reed pens on the dried and flattened stems of a local plant called

papyrus. The script consisted of symbols representing different ideas and sounds.

The walls of Egyptian monuments were decorated with hieroglyphics.

Developments in science and technology

The Egyptians devised a system of counting in tens. They also learnt how to

calculate the areas of triangles and rectangles.

The Egyptians developed a solar calendar. They observed that the interval between

two floods was 365 days, and divided this period into 12 months of 30 days each.

The remaining five days were set aside for festivals. The Egyptian year, therefore,

fell short of the solar year by one fourth of a day only.The Egyptian year began

when Sirius, the brightest star, appeared in the morning sky.

The most wonderful creations of the Egyptians are the pyramids, which were built

as tombs of pharaohs. Each one contained a king’s mummy and his precious

belongings.The Great Pyramid at Giza near Cairo was built for the pharaoh Khufu.

They also built temples decorated with huge statues and massive columns.The

Egyptians also made figures of a mythological animal called the sphinx.The

sphinx usually had the body of a lion and the head of a man.

The Pyramids at Giza The Great Sphinx at Giza.

Chinese Civilisation

The Bronze Age civilisation in China developed along the river Hwang- Ho around 1765

BC. The Hwang- Ho is called the ‘ Sorrow of China’ as it often changes its course after a

flood’ causing a lot of damage. The Chinese civilisation flourished first under the Shang

dynasty and then under the Chou dynasty.

Source materials- The literary source materials include records maintained on bamboo

strips, bone and silk scrolls.

The archaeological source materials include the following.

Building structures like large platforms which

bear impressions of buildings such as palaces,

administrative buildings, temples and workshops

for the production of various kinds of goods.

Bronze tools, weapons and vessels, porcelain,

jade, pottery, bamboo and silk goods; tortoise

shells and bones used for predictions by oracles.

Town Planning

The ancient Chinese city of Anyang in the Henan province of China was laid out on both

sides of a river. Along the city streets were situated palaces, temples and administrative

buildings. Along these streets were workshops involved in making pottery, jade and

porcelain goods, and bronze- casting.

Social Life

The king held the highest position in society. He was assisted by a class of nobles

who gave him military support and received land grants in return.

As wars were frequent, soldiers held an important position in society.

The merchants and craftsmen came next, followed by the farmers.

The slaves were at the lowest level of society.

Occupations

Agriculture was the chief occupation of the people. The Chinese grew millets, rice

and wheat. They had an elaborate system of irrigation.

The Chinese wove linen and acquired special skills in making silk from the

cocoons of silkworms.

They were skilled potters, and made remarkable porcelain crockery.

They mastered metallurgical skills as well, especially bronze-casting.

Religion

The Chinese worshipped the forces of nature. Ancestor worship also prevailed in

ancient China.

The Chinese consulted oracles, or priests, to learn about the future. The oracles

held tortoise shells or cattle bones over fire. When cracks appeared, they

interpreted them to predict the future.

Script – Initially, the Chinese script was pictographic,

that means words were represented by pictures. Later on,

pictures were replaced by signs, each sign representing

an idea.The script was written with artistic brushstrokes

on silk, bone or bamboo strips.

Early Chinese script on bone

Developments in science and technology –

The Chinese calculated the length of the year very accurately as 365 ¼ days. They did

this by combining solar and lunar calculations. They could even predict eclipses.

Class 6 Science Worksheet-5 (Chemistry)

Topic:The kinetic theory of matter

The idea that all substances contain incredibly small moving particles is called kinetic

theory of Matter.

The main points of kinetic theory are

1. All Matter is made up of tiny, invisible,moving particles. These particles are

actually atoms,molecules and ions.

2. Particles of different substances have different sizes

3. Small particles move faster than larger particles at the same temperature

4. As the temperature rises, the particles possess more energy and move around

faster.

5. In a solid , the particles are very close and they can only vibrate about fixed

position.

6. In a liquid, the particles are further apart.They have more energy and they can

roll around each other.

7. In a gas,the particles are far apart. They move very fast and randomly in all the

space they can find..

Change of state

Matter can be changed from one form to another e.g. ice (solid) on heating changes to

water (liquid) and on further heating changes to steam(gas).

Class 6 Maths Worksheet-5

TOPIC- FUNDAMENTAL OPERATIONS ON WHOLE NUMBERS

Properties Of Addition:-

1) Closure Property :- If ‘a’ and ‘b’ are whole numbers then a + b is also a whole

number. Example:- 18 +4 = 22

2) Commutative Property :- If ‘a’ and ‘b’ are any whole numbers

then ‘a+b’ = ‘b+a’ Example:- 20+10=30; And 10+20=30

3) Associative Law :- If a,b and c are a ny whole numbers then (a+b)+c =

a+(b+c).

Example:- (8+13)+6=21+6=27; 8+(13+6)= 8+19 =27.

4) Additive Identity :- If ‘a’ is any whole number then a+0 = a = 0+a

Example :- 25 +0 =25 ; 0+25 =25.

5) Cancellation Law :- If a, b and c are whole numbers then a+c = b+c; a=b.

Example :- If ‘x’ is a whole number, then x+5 =3 +5 ; x = 3

Properties of Multiplication :-

1) Closure Property :- If ‘a’ and ‘b’ are any two whole numbers then ‘a x b’ is also a

whole number. Example :- 23 x 3 = 69.

2) Commutative Property :- If ‘a’ and ‘b’ are any two whole numbers then

a x b = b x a. Example :- 9x7 =63 ; 7 x 9=63

3) Associative Law :- If ‘a’, ‘ b’ and ‘c’ are any whole numbers then

(a x b) xc = a x ( b x c) Example :- (7 x9) x5 =63 x5 =315;7x(9x5)=7 x45 =315

4) Distributive law:- If a, b and c are any whole numbers then

a x (b+c) = a x b+a x c

5) Multiplicative identity:- If a is any whole number, then a x 1 = a = 1 x a

Example:- 25x1=25=1x25

6) Multiplication by zero:- If a is any whole number, then a x 0=0=0 x a

Example:- 72 x 0=0=0x72

7) Cancellation law:- If a and b are any whole number and c is a non-zero whole

number then a x c = b x c; a=b

Example:- If y is a whole number, then
