Clothes We Wear     We wear clothes to protect ourselves from heat, cold and dust. In the previous class you have learnt about the various types of clothes like shirt, trouser, sweater, etc. We wear different types of clothes at different times and in different seasons. We wear cotton clothes in summer. We wear woollen clothes in winter. We wear raincoat during rainy seasons. We wear uniform in school. We wear formal dress when we go to a party or attend any function.   Sources of Clothes We obtain clothes from both plants and animals.   Clothes obtained from animals We get the following types of clothes from animals: (i) Silk (ii) Wool   Silk We get silk from silkworm. Silkworm is a type of insect. They feed on mulberry leaves. They give out a long, sticky thread from their mouth. These thread are wrapped around their body and become their home, known as cocoon. The threads of cocoon are collected, processed and then woven to make silk.     Silk clothes   Wool Sheep gives us wool. The thick hair that grows on the body of a sheep is collected, then cleaned and made into woollen threads. Wool is used to knit sweaters, caps, shawls, etc. It keeps us warm during winter.                                 Sweater                       Whool   Clothes obtained from plants We get the following types of clothes from plants. (i) Cotton (ii) Jute   Cotton Cotton clothes are made from cotton plants. Cotton grows in pods. The pods are picked and thread is made from the cotton. Making thread from cotton is known as spinning. Weaving is the process of making clothes from thread.   Cotton Clothes   Jute Jute is one of the cheapest natural fibre, which is used for making things for our regular use. For example, rope, bag, mat, etc. are made up of jute fibres. Jute fibres are pale yellow in colour and are quite strong. They have a silky lustre and are also used in making clothes.                  Care of Clothes

• Naphthalene balls and dried leaves of neem keep insects away from the clothes.
• Clothes should be properly rinsed in water and regularly washed.
• Cotton clothes are washed with soap and water.
• Silk and woollen clothes need dry cleaning.

 

Water, Air, Weather and Seasons   Air and water are all around us. We cannot see air but can feel it when it is moving. All living beings need air and water to live and grow.               Water animals                                     Water plants   Water More than two third of the earth is covered with water. Water is found in rivers, lakes, oceans, seas, etc. These are called water bodies. Most of the water on the earth is salt water. Salt water is filled with salt and we cannot drink it. We need fresh water to drink, which is only a very little portion of all the available water on earth. Again, of the available fresh water, a major portion is glacier ice, at the north and south Poles. It is too far away from where most of the people live. Therefore, we cannot use it.   Uses of water

• Drinking
• Washing
• Bathing
• Transportation
• Heating and cooling
• In industry and for many other purposes.

  Air Air is all around us. We cannot see it. But we can feel it. Moving air is called wind. A gentle wind is called breeze.

Unclean air makes us sick. We get fresh air from trees and plants. Now-a-days air in cities and town has become polluted because of too many vehicles and fewer trees.   Weather Our earth is surrounded by air. Sometimes this air becomes cold, sometimes hot. Sometimes we have rain, sometimes it is neither too hot nor too cold. This condition of a place, at any given time, is called weather.                                            Flowers                                                                        Snow                                             Rain                                                     Sunny day     Weather is not same all through the year.
