CBSE Class 9 Science Syllabus 2026–27 (NEP 2020 Updated | NCERT Integrated Science + Chapter List)

As per NEP 2020 & updated by NCERT (for CBSE)

The CBSE Class 9 Science Syllabus 2026–27 has been updated in line with the National Education Policy 2020 and latest framework released by NCERT. The syllabus now follows an integrated science approach, where Physics, Chemistry, Biology, and Earth Science are taught together instead of as separate subjects. This change shifts the focus from theory-heavy learning to conceptual understanding, inquiry, and real-life application, with increasing emphasis on competency-based education (CG-1 to CG-8).

Major Structural Change: Science now includes 4 components:–

• Science is now Integrated (Physics + Chemistry + Biology + Earth Science)
• Earth Science is introduced as a new component
• Learning is competency-based (As per document from CG-1 to CG-8) Focus more on:

1. Experiments                2. Data Interpretation                  3. Real life application

Assessment shifting towards:–

1. Case-based                 2. Application-based                    3. Reasoning based questions

Overall Change Snapshot

Science syllabus is not reduced or increased drastically it is reorganised with deeper concepts, practical applications, and the addition of Earth Science as an integrated component.

Subject-wise Change – Important Analysis

1. PHYSICS

Subject     Chapter /             Status                           What Exactly Changed /           Key Topics / Concepts Area                                                           Added
Motion	Strengthened	More analytical approach	Graphs, velocity, acceleration
Force & Laws of Motion	Strengthened	Application-based learning	Newton’s laws, momentum
Gravitation*	Concepts absorbed	Concept clarity improved	Mass vs weight, gravity
Work & Energy	Strengthened	Conceptual + Numerical focus	Energy conservation
Electricity*	Concepts absorbed	Strong real-life application added	Ohm’s law, circuits
Sound	Continued	More conceptual clarity	Waves, frequency
Overall Physics	Major Shift	Question pattern change	Numerical + graph + application-based

Conclusion: Physics now numerical + reasoning-based

*NOT a standalone chapter in new structure.

2. CHEMISTRY

Subject	Chapter / Area	Status	What Exactly Changed / Added	Key Topics / Concepts
Chemistry	Is Matter Around Us is Pure	Reorganised & expanded	Content retained with updated techniques	Mixtures, solutions, colloids, suspensions
	Added		New separation techniques introduced	Chromatography, Centrifugation, Coagulation
	Added		Introduced Numerical understanding	Concentration (m/m, m/v, v/v)
	Atoms & Molecules	Strengthened	Same chapter but more focus on application	Laws of chemical combination, formula writing
	Added Depth		Numerical & logical approach increased	Molecular mass, formula unit
	Structure of Atom	Strengthened	Conceptual depth increased	Bohr model, valency
	Added		Advanced atomic understanding	Isotopes, Isobars
	Chemical Reactions (basic)*	Early Introduction	Introduced earlier than before	Chemical equations, reactions basics

Conclusion: Chemistry becomes more practical + process-based

*NOT a standalone chapter in new structure.

3. BIOLOGY

Subject     Chapter / Area		Status	What Exactly Changed / Added	Key Topics / Concepts
Biology	Cell	Expanded	New real-life & advanced concepts added	Cell division, cancer
		Added	Experimental understanding	Osmosis
	Tissues	Expanded	Health-based integration	Musculoskeletal system
		Added	Practical life concepts	Posture, yoga
	Reproduction	Expanded	Detailed human biology added	Human reproduction
		Added	Awareness-based content	Reproductive health
	Diversity	Strengthened	Classification improved	Five-kingdom classification
	Genetics (intro)*	Early Entry	Introduced earlier than before	DNA, genes, heredity

Conclusion: Biology becomes deeper + slightly advanced

*NOT a standalone chapter in new structure.

4. EARTH SCIENCE (BIGGEST CHANGE)

Introduced as a new standalone theme (Earth as a System: Energy, Matter and Life), with concepts also integrated across other topics.

Subject	Chapter / Area	Status	What Exactly Changed / Added	Key Topics / Concepts
Earth Science	Earth as a System	New Addition	Introduced as new component (C-2.8)	Integrated system understanding
		Added	Core Earth systems included	Atmosphere
		Added		Hydrosphere
