ENVIRONMENTAL STUDIES:

CBSE CLASS III

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.

A BEAUTIFUL CLOTH- TEXT

A BEAUTIFUL CLOTH

CBSE CLASS III

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,

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.
