Class 9 Science Chapter 1, Exploration: Entering the World of Secondary Science, is the short opening chapter of the new NCERT science book Exploration (2026-27). It has no formulas or experiments of its own; instead it explains how science at the secondary stage differs from the middle-stage Curiosity books: less about what we know and more about how we know it.
What Class 9 Science Chapter 1 Covers
The chapter describes the habits the rest of the book will ask of you: turning observations into measurements, expressing patterns with symbols and equations, building models to represent complex systems, and testing ideas that are then revised or sometimes discarded. It also explains why scientists first study simplified, idealised forms of a phenomenon, an approach Chapter 4 uses when it treats motion in a straight line before circular motion.
It is worth reading before the physics, chemistry and biology chapters because it introduces the recurring features of every later chapter: the Think It Over questions at the start, the At a Glance summary, the Revise, Reflect, Refine questions and The Journey Beyond projects at the end.
