children have read about trees, water, houses, animals, vehicles and many other things. You must have thought about them as well.
 Can you tell, why did we try to know and think about all these things?
How are we linked to the things shown in the picture? 
Come, let us find out Let's see, with what other things can we join the house to. Think – What is a house made of ?

Wood – Which comes from trees.
Bricks – Which are made from water and clay.
Clay – We get from the soil, and
Water – we get it from rivers, ponds, wells or rain.
It must be clear to you with which pictures or words you need to join the house.In the same way, join all the things with other things related to them. While doing so, you might need to write the names of a few more things.
The world in which we called as environment. We can see trees, rivers, mountains, sun, land, animals, human beings, soil in the nature.These things include both living and non-living.
plants animals and human beings are living things. The living things are called the Biotic components of environment. Non –living things include air, water, light, soil etc. they are called the A biotic components of the environment.
The  biotic and ABIOTIC components of the environment interact with each other. They depend on one another. This relationship is called ecosystem.
Human beings depend on plants and animals for their food and other needs and so are animals on plants. We depend on non-living things also. Air, water and soil are the non-living . living things depend on non-living things for their existence.
Animals directly are indirectly depend in plants for their food. animals depends on plants for food, oxygen and shelther.
Plants use carbondioxide released by animals during respiration while making their food.The plants in trun are dependent on the soil for food. Plants require nutrients for sustaining life. Decompose the dead animals in soil and release nutrients.
Animals help in dispersal of seeds and fruits so that they get favorable environment, to germinate and grow.
Thus, we see that living and non-living components of environment are interdependent. They support each other and maintain a balance in nature. Man should not disturb this balance through his activities.



Sajida's sister gave her a very beautiful dupatta. The dupatta had beautiful embroidery and small mirrors stuck on it. After finishing dinner, Sajida tried to wear the dupatta in different ways.

Soon she got tired playing with the dupatta and fell asleep wearing it. She was thinking about the dupatta even in her dream. How would such a beautiful dupatta have been made?  Let us know different of clothes at  that made from different materials.
Clothing  is and has been made from many materials. Clothing is generally made of cloth. There are many different types of cloth, with different names and uses. Different types of cloth are used for different types of clothing.
Cloths are made  from the. They are made up of two types of fibers. Natural fibers  these comes from plants and animals which are available in nature. synthetic fibers these are from chemicals. these are also called man-made fibers.
Natural fibers these comes from nature. Example cotton, silk, wool etc.
Cotton comes from plant. We use cotton in summer season. They observe sweat and keep our body cool.
Silk comes from silk worm called cocoon. We wear silk clothes in rainy season. It gives a special appearances. They do not observe water. So clothes can dry without sunlight.

Woolen clothes are made from wool. Wool comes from sheep hair by shearing. We wear woolen in winter season to keep our body warm.
Synthetic fibers
As fibers manufactured from using the industrial process, synthetic fibers aren’t found in nature. Recent years have seen increased demand for synthetic fabrics such as nylon, polyester and spandex. Readily available and affordable, synthetic fabrics are integral to a wealth of clothing designs.
Some clothing is made from synthetic fibers, which are man made and generally not  biodegradable. These are made primarily from  petrochemicals.
Common man-made materials include:
Nylon is first produced in 1935. Nylon is thermoplastic silky material. It became famous from1940.It was intended to be a synthetic replacement for silk  and substituted for it in many different products after silk became scarce during World War II.
Polyesters include naturally-occurring chemicals and synthetics. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not. Polyesters may change shape after the application of heat and are combustible at high temperatures.
Spandex (elastane) is known for its exceptional elasticity. It is stronger and more durable than rubber, its major non-synthetic competitor. It was invented in 1959 by Charles Lewis French Jr. and Taylor.
We wear clothes studied to the climate. Clothes should be clean and comfortable. Clothes protect us against heat, cold, rain, dust and insects.



The hand which fits on the hand in the picture is your right hand. Place your other hand on a page in your notebook and trace its outline with your right hand to get a picture. The hand whose outline you have just traced is your left hand.

Let us sing a song.
Put your right hand in,
Put your right hand out,
Put your right hand in,
and just turn around.

Put your left hand in
Put your left hand out,
Put your left hand in,
and just turn around

The Rules Of The Road Regulations,1989 was brought into effect from July 1, 1989. It deals with basic facts such as overtaking, traffic signals, , speed limits.
Guide Ruchira from home to school. Find the school in the picture. Also find the way from Ruchira’s home to her school. Now, with a coloured pencil trace the way from Ruchira’s home to her school.

For a road with a sidewalk only on one side, it is recommended to use the sidewalk for traveling in either direction (with traffic or against traffic). Again the sidewalk helps separate you from the automobiles.

If no sidewalks exist on the road, it is recommended to walk facing oncoming traffic on the same side of the road as the oncoming traffic.
 Also, you should get as far to the side of the road as possible to provide additional space between you and oncoming cars.When bicycling, you will want to ride on the right (going in the same 

If you observe the pedestrian traffic in India, not everyone walks on the left side, in fact the pedestrian traffic moves in both directions. So, there are people who walk on their right side as well.
Despite the fact that walking on the right gives a better view of the oncoming vehicular traffic, some possible reasons for why pedestrians walk on their left or right:
With our Road Symbol Signs and Traffic Symbol Signs you can make your traffic directions as simple and seamless as possible. 
Everyone who has a drivers license is required to understand the meaning of each of these signs. Our Traffic Symbol Signs put the options in your hands.



Come, let us play a game together. You must be familiar with this game. All the children stand in a circle.
Let one child stand in the centre and play a tune. Everyone must run in a circle as long as the music plays. The child who is playing the music, will suddenly stop it and call out a small number like ‘five’, ‘four’ or ‘two’ loudly. Children have to form groups according to the number called out.
The children who cannot join any group will have to leavethe game. Continue to play this game till only two children are left in the circle.
All of us prefer to live with people than to live alone. We always live in groups. Let’s see one such group – Gurleen, Nagarajan and their children Tanya and Samar.
The people in the picture you saw belong to one family. We often see pictures or photographs of such families. Where do we see such a family? Are all families similar to this one ? Let us read about a few families.


Sitamma lives in her ancestral house in a small city Guntoor. Her dada, dadi, younger chacha and bua live on the ground floor. In one portion of the first floor, Sitamma lives with her father, mother and younger sister Gitamma. In the other portion live her tauji and his three children.
Her taiji died just a few months ago. Her elder chacha and the new chachi live in one of the rooms on the terrace. They are newly married.
Before dinner, Sitamma’s mother teaches all the children. Food for the whole family is cooked in the same kitchen on the ground floor. They all make special effort to be together at dinner time.

Nowadays, tauji ’s younger daughter sleeps with Sitamma’s mother at night. In the morning Sitamma helps her get ready for school.

Tara lives with her amma and nana in Chennai. Her amma Meenakshi is not married. She has adopted Tara. Meenakshi goes to the office in the morning and returns in the evening.
When Tara returns from school, her nana takes care of her. He is the one who feeds her, helps her to do homework and also plays with her.

During vacations, the three of them go to far off places and enjoy themselves. At times, Tara’s mausi, mausa and their children also come to their house. At such times they play together for long hours and also chit chat.

Sara and Habib live in a city. Both are employed. Habib is a clerk in a government office and Sara teaches in a school. Habib’s abbu is retired and lives with them.
In the evening, the three of them sit together and watch television or play cards. Abbu enjoys watching television with the others. He enjoys the discussion as well. On holidays, the neighbour’s children come to their house and create a lot of fun. Everybody enjoys together. They play games, go out and at times go for plays and movies.


Totaram lives with his father, uncle and cousin brothers in a colony in Mumbai. Totaram and his brothers have come to Mumbai to study. His father and uncle work here.
Everybody does the household work together. Food cooked by Totaram’s chacha is liked by everyone.Totaram’s father does the shopping.

A part of the money earned is sent to Totaram’s dada in the village. Totaram’s mother, dada, dadi, chachi and younger brothers and sisters live in their parental house in the village. Once a year, Totaram goes to his village. He misses his mother very much. He writes long letters to her.

Krishna and kavari

Krishna and Kaveri live with their father. In the morning, all the three leave home together. krishna lives kavari at school and goes to college. Their father go to the shop for the day.
Kaveri returns from school in the afternoon. She unlocks the house
and waits for Krishna. On returning from college,Krishna and kavari eat food together.Kaveri goes out to play after doing her school work.

 On returning she either plays carom with her brother or watches television. When father returns home, they cook food and then eat together.

During vacations, Kaveri goes to stay with her mother. Krishna
also stays there for a few days, but he likes to stay in his own
house – all his things and his father are here.

There may be other differences: some couples may marry at a young age and some people find a partner when they are older; some families with children are led by one parent because of death, separation, or divorce; some couples have no children, yet they consider themselves to be a family; some people have one child, while others have many children born to them.

Many families adopt a child or several children.  When we talk about our family, we usually refer to the people who live with us.
All of our relatives, such as cousins, aunts, uncles, and grandparents, are part of our family. Whether they live in a separate place down the block or across town, or even far away from us in another part of Canada or in a foreign land, they are still part of our family.
Not everyone knows all their grandparents  because they are no longer alive. These family members are remembered in stories told about the good times when you were a baby or before you were born.

 Nowadays, it is wonderful for families that even those who live far away can both hear and see each other through the use of computer web-cams and other modern communication systems.And all through it shines by God’s love.




Madho lives in Bajju- a small village in Rajasthan. It is hardly
a village ! All you see is sand all around. One can see some houses when the sand does not blow.
 Everyone in Madho’s family is upset. Every summer there is water scarcity in his place. This year, it is worse. It did not rain at all. His mother and sister have to walk a longer distance to fetch water as the nearby pond has also dried. Each day they spend hours just to get four pots of water. While walking on the hot sand their feet burn and blisters just cannot be avoided.

When the train carrying water comes they are very happy. Madho’s father goes to fetch water in his camel-cart. But this does not happen often.

People keep waiting days and days for water. Some people collect rain water. This is done by a special method  by making tanks (tanka). Do you know, what a tanka is and how it is built?

1To build a tanka, a pit is dug in the courtyard and it is made pucca. The tanka is kept covered with a lid. The roof of the house is made sloping so that the rainwater collected here flows through a pipe into the tanka.

A sieve is attached to the mouth of the pipe so that no dirt goes into the tanka. This water is used for drinking after it is cleaned.

Just like Madho, Sonal also faces water scarcity in her house. She lives in Bhavnagar. Water is supplied only for half an hour in a day. All the people of the area depend on only a single tap ! Can you imagine what happens ?

Sonal is determined to take water from the tap. Whenever she gets a chance she fills her bucket even if it is just drop by drop. Let us find out how many drops will fill a bowl or a mug.

Water scarcity can be defined as a lack of sufficient water, or not having access to safe water supplies.Water is a pressing need in many areas of the world.

That scarcity is spreading as water is needed to grow and process food, create energy, and power industry for a continually growing population. climate change is a key contributing factor.

Clean, potable water is an essential ingredient of a healthy human life, but 1.2 billion people lack access to water according to recent estimates from the International Water Management Institute cited in the worlds water.
Storing and Moving Water
Understanding where your water comes from will help you understand what you can do to mitigate the effects of drought. Your water supply might be from surface or from groundwater. Conserving water is the best way for us to make sure that we all have water even when we are in drought.

To make sure that they have enough water throughout the year, people build dam  to store water when they need it.then a dam is built on a river, a large lake, called a reservoir, is made. The reservoir “stores” the water for people’s use. Reservoirs can provide fish and wildlife habitat and also are often great places for us to boat and fish. They also can be used to produce power.

Groundwater and Wells
Another source of water is groundwater (water found below the surface of the earth). aquifers are like underground lakes. Just like lakes above the ground, aquifers can be different sizes. Some are very small and some are very large, like the Ogallala Aquifer.

people drill wells into aquifers so they can bring water to the surface to use. Water in aquifers can be just a few feet below the earth’s surface or hundreds of feet deep. The water that is closer to the surface is easier for us to use, but it can also be more easily polluted than the water that is much deeper. 

Canals and Pipelines

Water canals and pipelines have been built in many places to make sure that as many people as possible have access to water supplies. Canals and pipelines are used to transport water from reservoirs and wells to farmers for irrigation and cities for drinking water. Canals like the Central Arizona Project and the Los Angeles Aqueduct carry billions of gallons of water each year to areas that do not have enough water

We need fresh water for drinking, for our daily activities, and for growing our food. But almost all of the water on the surface of the earth is salt water from the oceans and seas. In fact, 97 percent of all water on earth is salt water.

People have been trying to find a way to use ocean water in place of fresh water for many years. With new technology, turning seawater into water that we can drink and use is becoming much easier and much cheaper. 

Desalination, or removing salt from seawater, is still expensive, but some cities in the United States and other countries are building desalination plants to help them meet their water needs. 

Cleaning of water
To clean water we should have sewage treatment plants. when it, can be used again at home, agriculture in industry etc. so again the process is started.

Different methods of saving water
Daily we use 20% water in kitchen, 20% in garden, 20% in laundry% and 40% of water in our bath rooms.
Turn off the tap when brushing your teeth. A running tap can use six litres of water per minute. Use the minimum amount of water needed for a bath by closing the drain first and filling the bath only 1/3 full. Stopper bath before turning water. The initial burst of cold water can be warmed by adding hot water later.
Make your garden water efficient. Less watering doesn't have to mean less gardening! Start opting for plants that don't mind going without a drink for a while. Your garden centre will be able to recommend plants that need less water.
Don't leave the tap running to clean dishes or vegetables. Use a bowl of water instead. A running tap uses 6 litres of water per minute.
Take shorter showers - we recommend four minutes. On average a shower uses 10 litres of water a minute. Fully load your washing machine. A full load uses less water than two half-loads.
Only flush the toilet if you need to. On average, each flush uses 7 litres of water. Keep a jug of water in the fridge. Planning ahead means there is no need to run the water until it gets cold.
Verify that your home is leak-free, because many homes have hidden water leaks. Fix leaking taps. A dripping tap can waste more than 60 litres of water per week.
Order a water butt. Collect rainwater to use on your plants and lawn. Never put water down the drain when there may be another use for it such as watering a plant or garden, or cleaning.Store drinking water in the refrigerator rather than letting the tap run every time you want a cool glass of water.
You have given some suggestions to re-use water. People use these methods only under conditions when there is a scarcity of water. Do you know, one of the reasons for the scarcity of water is because people waste it. Just think, how good it would be if everyone got water !
