Materials Around Us
Clothes, vessels, books, and toys are made of different materials chosen for a purpose, the starting point of NCERT Curiosity for Class 6, Chapter 6. The chapter tests objects for appearance, hardness, roughness, solubility in water, heaviness, and transparency, sorting materials as shiny or dull, soluble or insoluble, transparent, translucent, or opaque. Activities show why steel suits cooking pots, glass suits windows, and cotton suits summer wear, and the chapter ends by urging sensible use and reuse of materials.
