Nature of Matter: Elements, Compounds, and Mixtures
This chapter of the Class 8 NCERT Curiosity textbook asks what everything around us is ultimately made of.

Symbols and formulae give the language of this classification, while filtration, evaporation, distillation, magnetic separation and chromatography show mixtures can be unmixed. Testing common substances reveals that properties, not appearances, decide whether matter is an element, a compound or a mixture.
