Measurement of Length and Motion
How long is the desk, and is the passing bus moving in a straight line or a curve, are questions NCERT Curiosity for Class 6, Chapter 5, sets out to answer. The chapter shows why hand-spans and cubits vary and standard units such as the metre matter, practises correct use of the ruler, and introduces the kilometre for longer distances. It then sorts motion into rectilinear, circular, and periodic kinds through everyday examples, and closes with activities that measure, record, and compare lengths and movements carefully.
