Materials

This CTET Paper 2 chapter builds Class VI Materials (Sorting Materials into Groups) for future VI-VIII Science teachers: object versus material, appearance (lustre), hardness, solubility in water, transparency (transparent, translucent, opaque), floating and sinking, grouping activities, pedagogy of property-testing traps, fair-test habits, safety and low-cost TLM. Materials of daily use (c2-2-04) stays a one-line sibling only.
