Paheli and Boojho won the first

prize in a Science Quiz

competition held at their school.

They were very excited and decided to

use the prize money to buy clothes for

their parents. When they saw a large

variety of cloth material, they got

confused (Fig. 3.1). The shopkeeper

explained that some clothes or fabrics

were cotton and some were synthetic.

He also had woollen mufflers and

shawls. There were many silk sarees as

well. Paheli and Boojho felt very excited.

They touched and felt these different

fabrics. Finally, they bought a woollen

muffler and a cotton saree.

After their visit to the cloth shop,

Paheli and Boojho began to notice

various fabrics in their surroundings.

They found that bed sheets, blankets,

curtains, tablecloths, towels and

dusters were made from different kinds

of fabrics. Even their school bags and

the gunny bags were made from

some kind of fabric. They tried to

identify these fabrics as cotton, wool,

silk or synthetic. Can you also identify

some fabrics?

3.1 VARIETY IN FABRICS

Activity 1

Visit a nearby tailoring shop.

Collect cuttings of

fabrics leftover after

stitching. Feel and

touch each piece

of fabric. Now,

try to label some

of the fabrics as

cotton, silk, wool

or synthetic after

asking for help from the tailor.

Do you wonder what these different

fabrics are made of? When you look at

any fabric, it seems a continuous piece.

Now, look at it closely. What do you

notice (Fig. 3.2)?

Activity 2

Select a piece of cotton fabric you

labelled in Activity 1. Now, try to find a

loose thread or yarn at one of the edges

and pull it out (Fig. 3.3). If no loose
