Materials Around Us
About this chapter
Materials Around Us is the sixth chapter of Class 6 Curiosity. Through classroom scenes with Ghulan, Sheeta, Sara and Madam Vidya, students learn that every object is made of one or more materials — paper, wood, glass, clay, plastic, metal. The chapter builds the idea of classification: grouping materials by shared properties. Five physical properties are explored hands-on — lustre (lustrous and non-lustrous), hardness (hard and soft, by pressing or scratching), transparency (transparent, translucent, opaque), solubility in water (soluble and insoluble), and being heavy or light (mass). Volume — the space an object occupies — comes in through two glass tumblers of unequal water levels. Mass and volume together define matter. The chapter closes with the Ayurvedic ten pairs of guṇa as a parallel Indian classification. CTET Paper 2 Science most often tests property–example matches (which material is opaque), the relative nature of hard/soft, soluble/insoluble examples, and the matter–mass–volume link. The four tests below — Practice 15 Q, Quiz 15 Q, Hard 15 Q, Mastery 30 Q — cover these ideas at exam depth.
