Question

(2) Nehabhabhi takes two types of fiber, natural and synthetic. She does not know

which one is natural fiber and which is synthetic fiber. Which activity you will suggest

to identify the fibers?​

Answer 1

Explanation:

Take two cloth pieces of the same

size, roughly half a metre square

each. One of these should be from

natural fibre. The other could be a

synthetic fibre. You can take help

of your parents in selecting these

pieces. Soak the pieces in different

mugs each containing the same

amount of water. Take the pieces

out of the containers after five

minutes and spread them in the sun

for a few minutes. Compare the

volume of the water remaining in

each container.
