NCERT Class 9 Science
NCERT Class 9 science is an important class. There are two reasons, Firstly it’s conceptual foundation building that helps in the succeeding classes. Secondly, the upcoming class is a board class and you decide a pathway for your future.
When a student studies as the science class 9 syllabus helps in building a foundation for upcoming years. NCERT Class 9 science book is essential for getting acquainted with modern concepts. NCERT Class 9 science book is written by subject experts to make roads inquisitive minds for wider thinking.
NCERT textbooks help teachers, and educators make notes, assignments, and tests that abreast the aspirant’s knowledge. Through the assignment, an aspirant develops self-study methods. Also, the NCERT class 9 science book is written in very simple language which is easy to understand and digest the core idea.

Matter- Its Nature and Behaviour
This Unit of NCERT Class 9 science deals with the theme of Materials which includes
Unit I: Matter-Nature and Behaviour
Definition of matter; solid, liquid, and gas; characteristics – shape, volume, density; change of statemelting (absorption of heat), freezing, evaporation (cooling by evaporation), condensation, sublimation.
Nature of matter: Elements, compounds, and mixtures. Heterogeneous and homogenous mixtures, colloids, and suspensions. Physical and chemical changes (excluding separating the components of a mixture).
Particle nature and their basic units: Atoms and molecules, Law of Chemical Combination, Chemical formula of common compounds, Atomic and molecular masses.
Structure of atoms: Electrons, protons and neutrons, Valency, Atomic Number and Mass Number, Isotopes and Isobars.
To strengthen the NCERT Class 9 Science Chapter problem conceptual understanding is not only necessary for the exams but they are also crucial for building fundamentals for upcoming boards class.
