Q7. In weaving, what happens when vertical and horizontal threads cross over and under each other?
Answer: A — When vertical and horizontal threads are carefully crossed over and under, they interlace to create a strong, unified fabric.
Q8. Which Indian handloom cloth represents self-reliance and was promoted during the freedom struggle?

Which bird weaves beautiful hanging nests from grass?
The baya weaver bird weaves hanging pouch-shaped nests from grass by crossing strands over and under.
What is spinning?
Spinning is the process of twisting cotton fibres together to make thread or yarn stronger and thinner.
Name three natural fibres used to make cloth.
Cotton, silk, wool, jute, bamboo and linen are natural fibres used to make cloth.
Where does silk fibre come from?
Silk fibre comes from the cocoon of a small insect called the silk moth.
What is a charkha or spinning wheel used for?
A charkha is used to spin thread from cotton fibres by twisting them together, just like our fingers or a pencil do.
Which special Indian cloth is made by hand spinning and represents self-reliance?
Khadi is the cloth made by hand spinning thread from cotton and weaving it, which became a symbol of the freedom struggle.
Which tiny green bird stitches its own nest using its beak?
The tailorbird stitches leaf edges together using its beak and plant fibres or spider silk to make a safe nest.
What is the basic running stitch?
Running stitch is a simple stitching method where the needle goes up, down, up, down in a straight line through cloth.
Name two synthetic fibres used in clothes.
Rayon, nylon, polyester and terylene are synthetic fibres made by humans using artificial materials.
What is weaving? [1 mark]
Define weaving as crossing threads over and under; mention it creates cloth, mats or baskets.
Name any three natural fibres used to make cloth. Why are they called natural? [2 marks]
List three from: cotton, silk, wool, jute, bamboo, linen. Natural fibres come from plants and animals in nature, not made by humans.
How does the tailorbird stitch its nest? Describe the process in your own words with an example from how humans stitch clothes. [3 marks]
Tailorbird uses beak to poke holes in leaf edges and pulls plant fibres or spider silk through; similar to how tailors sew cloth with needle and thread.
Explain the process of making thread from cotton. What is spinning? Draw and label the steps involved from cotton plant to thread. [5 marks]
Spinning = twisting cotton fibres to make them stronger and thinner; include steps: pull cotton fibre → twist it → wind on pencil/charkha → creates thread; mention charkha is traditional spinning wheel.
State whether these statements are true or false. Give one reason for each answer. (a) Silk is a synthetic fibre. (b) Khadi cloth is made by hand spinning and weaving. [2 marks]
(a) False — silk comes from silkworm cocoon (natural fibre). (b) True — khadi is hand-spun and woven cotton cloth that represents self-reliance.
Q1. Assertion (A):
The baya weaver bird is a hidden artist in nature.
Reason (R):
It builds beautiful hanging nests by weaving grass strands over and under each other.
Answer: A — Both A and R are true, and R is the correct explanation of A — Both statements are true, and the reason correctly explains why the baya weaver is considered a hidden artist — because it weaves, designs, and creates strong nests like an artist.
Q2. Assertion (A):
Synthetic fibres are better than natural fibres for making clothes.
Reason (R):
Synthetic fibres like polyester and nylon are made by humans using artificial materials.
Answer: D — A is false but R is true — The reason is true (synthetic fibres are made artificially), but the assertion is false because the chapter does not say synthetic is better — we use both natural and synthetic fibres for different purposes.
Q3. Assertion (A):
The tailorbird is important for understanding how humans stitch cloth.
Reason (R):
The tailorbird sews the edges of leaves together using its beak and plant fibres, just like tailors use needles and thread to stitch cloth.
Answer: A — Both A and R are true, and R is the correct explanation of A — Both statements are true, and the reason correctly explains why the tailorbird's stitching is an example of how humans learned stitching techniques from nature.

Case Study:
Priya visited her grandmother's house and found her making a scarf from cotton. First, her grandmother took some fluffy cotton and twisted it with her fingers to make it strong. Then, she used a spinning wheel to twist more cotton fibres together. Finally, she took the thread and wove it on her loom to create a beautiful scarf. Priya asked, 'Grandma, what are you making?' Her grandmother smiled and said, 'This is khadi, beta. It is cloth made by spinning and weaving by hand, just like Gandhi ji did during the freedom struggle.'

Answer: A
Q2. What is the name of the hand tool used to twist cotton fibres into thread?
Answer: C
