Overview of the CBSE syllabus for class 9 Science syllabus 2024-25

Chapter 1: Matter in Our Surrounding

Matter in Our Surrounding is the first chapter of the ncert class 9 science. The chapter defines matter as something which occupies space and has mass. It discusses how the Indian philosophers have classified matter into different elements as Panch Tatva, comprising air, water, sky, fire and earth. However, modern scientists classify matter into two types such as physical and chemical properties. The main topics discussed in the chapters are:

Definition of matter

Solid, Liquid and Gas

Characteristics – Shape, Volume, Density

Change of state –  Melting, Freezing, Evaporation, Condensation, Sublimation.

Chapter 2: Is Matter Around Us Pure?

The second chapter of the ncert class 9 science book, Is Matter Around Us Pure, helps students learn about mixtures, solutions, and its properties, separation of mixtures followed by physical and chemical changes. Students also gain insights on Compounds and its properties, the difference between a compound and a mixture, etc. Let’s see what topics are some important topics covered:

Nature of matter: Elements, compounds and mixtures

Heterogeneous Mixtures

Homogeneous Mixtures

Colloids and Suspensions

Physical and Chemical changes

Chapter 3: Atoms and Molecules

Atoms and Molecules is the third chapter of the ncert class 9 science which deals with laws of chemical combination, atoms, molecules, etc. Students will learn to write chemical formulas, molecular mass and mole concepts. Some important topics covered here are:
