What's new in the 2026-27 syllabus?

This is a genuinely integrated syllabus — Biology, Chemistry, Physics and Earth Science are woven together rather than taught as separate blocks, aligned with NCF-SE 2023 and NEP 2020. New additions include Patterns in Life: Diversity and Classification, Reproduction: How Life Continues, and an entirely new unit, Earth as a System — alongside revised versions of familiar chapters like Cell, Atomic Foundations of Matter, Motion, and Sound.

The New Class 9 Science Textbook — Exploration

NCERT has introduced a significantly revised Science textbook for Class 9 from 2026-27 — Exploration. The approach is more curiosity-led, more activity-based, and more focused on in-text questions that develop thinking rather than rote recall.

Science at Advanced Level (Optional)

From 2026-27, CBSE has introduced an Advanced Level in Science alongside the standard course for Class 9 (extending to Class 10 in 2027-28). It is entirely optional — students may choose to appear for the Advanced exam in addition to, not instead of, the mandatory Standard Science paper. It is based on its own separate textbook, "Science at Advanced Level (Optional)", and is aimed at students who want to go beyond the standard syllabus with HOTS-style questions.

How the Advanced exam works

Separate optional paper, on top of the mandatory Standard Science exam — not a replacement for it

Every Class 9 student sits the mandatory Standard Science paper. Those who want an extra challenge can additionally opt for the Advanced exam, based on this separate textbook and weighted heavily towards Higher Order Thinking Skills (HOTS) questions. Students scoring 50% or above get "The Advanced Level has been successfully cleared" noted on their marksheet — but Advanced marks are not added into the overall aggregate. Students may choose no Advanced subject, only Maths Advanced, only Science Advanced, or both.
1
Measurement — Foundation of ScienceCGS/FPS/MKS & SI systems, unit conversion
2
Understanding Motion through ExperienceFrames of reference, scalars & vectors, equations of motion
3
Newton's Laws of MotionPseudo force, gravitation, variation of g with height & depth, torque
4
The Geometry of Power — Advanced Simple MachinesWheel & axle, mechanical advantage, tension
5
Work and EnergyConservative vs non-conservative forces, spring potential energy
6
Structure of AtomSubatomic particles, spectra, Bohr's model
7
Chemical BondingOctet rule & exceptions, metallic bonding, electron sea model
8
Mixtures and their SeparationChromatography, fractional distillation
9
Microscope and MicroscopyCompound & electron microscopes, magnification vs resolution
10
Engineering Life: Miracles in BiotechnologyGenetic engineering, fermenters, Bt crops, ethical issues
Optional exam 10 chapters Physics · Chemistry · Biology
Is Advanced Science right for your child?

The Advanced module goes noticeably deeper than the Standard syllabus — for instance, it introduces topics like pseudo force, spring potential energy derivations, electron sea model of metallic bonding, and full biotechnology (Bt crops, fermenters, rDNA technology) at the Class 9 level itself. It suits students who are already comfortable with the Standard syllabus and want an extra academic challenge — not a substitute for strengthening core fundamentals first.

Frequently Asked Questions

The 2026-27 syllabus (Subject Code 086) is organised into 4 units across 12 marked chapters (plus an introductory Chapter 1): Unit I — World of Living (Cell: The Building Block of Life, Tissues in Action, Reproduction: How Life Continues, Patterns in Life: Diversity and Classification — 27 marks), Unit II — Matter: Its Nature and Behaviour (Exploring Mixtures and their Separation, Journey Inside the Atom, Atomic Foundations of Matter — 25 marks), Unit III — Motion, Force, Work and Sound (Describing Motion Around Us, How Forces Affect Motion, Work Energy and Simple Machines, Sound Waves: Characteristics and Applications — 23 marks), and Unit IV — Earth as a System (5 marks). Total: 80 marks theory + 20 marks Internal Assessment.
Yes. The 2026-27 syllabus introduces an integrated approach combining Biology, Chemistry, Physics, and Earth Science, aligned with NCF-SE 2023 and NEP 2020. It replaces the earlier syllabus structure with new chapters including Diversity, Reproduction, and Earth as a System, alongside revised versions of familiar topics like Cell, Atoms and Molecules, Motion, and Sound.
Solutions are being added chapter-wise as they are completed, rather than all at once. Check back regularly — completed chapters will link directly to their solutions here.
The 80-mark theory paper is weighted: 50% Demonstrate Knowledge and Understanding, 30% Application of Knowledge/Concepts, and 20% Formulate, Analyze, Evaluate and Create. Question types include VSA/objective questions, Assertion-Reasoning, SA, LA, and Source/Case/Passage-based integrated questions, with roughly 33% internal choice.
From 2026-27, CBSE offers an optional Advanced Level exam in Science for Class 9 (extending to Class 10 in 2027-28), in addition to the mandatory Standard Science paper — not instead of it. It's based on a separate textbook covering 10 chapters across Physics, Chemistry and Biology (see the Advanced Science section above), and is weighted heavily towards HOTS (Higher Order Thinking Skills) questions. Students scoring 50% or above get a remark on their marksheet that the Advanced Level was cleared, though these marks aren't added to the overall aggregate.
