Clothes - How Things are Made
The chapter 'Clothes - How Things are Made' in the Class 5 EVS textbook 'Our Wondrous World' under WBBSE explores the fascinating journey of how different types of clothing are made. Students learn about natural and synthetic fibers, such as cotton, jute, silk, wool, and nylon, and how raw materials are transformed into finished garments through processes like spinning, weaving, and knitting. This chapter is very important for board exams as it helps students understand the source of everyday items, the hard work involved in making clothes, and the importance of traditional handicrafts and sustainable clothing choices.

Frequently Asked Questions
What is the difference between natural and synthetic fibers?
Natural fibers are obtained from plants and animals (like cotton and wool), whereas synthetic fibers are man-made using chemicals (like nylon and polyester).
How do we get silk from silkworms?
Silk is obtained from the cocoon of the silkworm. The cocoons are boiled to loosen the silk threads, which are then unwound and spun into silk yarn.
Why do we wear woolen clothes in winter?
Woolen clothes trap air between the fibers. Since air is a poor conductor of heat, it prevents our body heat from escaping and keeps us warm.
