Frequently Asked Questions
What is the main difference between a raw material and a finished product?
A raw material is the original natural substance (like raw cotton), while a finished product is the final usable item made from it (like a cotton shirt).
Why are clay pots used widely in Rajasthan during summer?
Clay pots have tiny pores that allow water to evaporate, which keeps the stored water naturally cool and refreshing during hot summer days.
How can we help save natural resources while making things?
We can reduce waste, reuse old items, and recycle materials like paper and plastic so that fewer trees and natural resources are cut down or used up.
