NCERT Class 9 Science — What Was Deleted in 2022

This page lists the content removed from NCERT Class 9 Science in the 2022 rationalisation. It is sourced from NCERT's official rationalisation booklet (BookletClass9.pdf) published in May 2022. All 2 items listed below are NOT in the current 2025-26 textbook.

How to use this Class 9 Science deletion list

This page is a reference index of what NCERT removed from Class 9 Science in the 2022 rationalisation. It is not a study guide. It is not a coaching pitch. It serves three specific reader workflows:

1. CBSE Class 9 board student, checking 'is this topic in the board paper?' — if a topic is on this page, it is NOT on the current board paper. You can safely skip it for the board exam.
2. Entrance-exam aspirant (NEET / JEE / CUET 2026), checking which deleted-NCERT topics still appear in the entrance-exam syllabus published by NTA. Cross-reference our per-exam deleted-syllabus pages for the actual reconciliation.
3. Teacher / counsellor / parent, helping a student understand 'why is this chapter in our older textbook but not in the current one'.

Important caveat. Some 'removed' topics were not deleted outright but relocated to a different class. For example, in Class 9 Maths, Probability was moved from Class 9 to Class 10. Always cross-reference the /ncert/old-vs-new-class-9-science page for the full side-by-side diff.

The deletion list itself comes from NCERT's official 2022 rationalisation booklet (BookletClass9.pdf on ncert.nic.in). We hot-link to it as the primary source for every claim on this page.

Find a school teaching NCERT Class 9 near you

How Science builds across classes in NCERT

Class 8 Science foundation. The chapters in Science you studied at Class 8 are the prerequisites for this material. If you found any Class 8 chapter difficult, revisiting it briefly before tackling the higher-order topics here pays off — the conceptual chain matters more than memorisation.

Class 10 Science preview. Next year's Science extends the conceptual frameworks introduced here. Strong Class 9 fundamentals make Class 10 manageable; weak Class 9 is the gap that compounds.

Three ways students and parents use this page

As a study reference. Bookmark it on your phone, share the URL with your child or study group, and refer back during the academic year. The page structure is intentionally stable — same hierarchy, same sources, same labels — so revisiting it weeks later doesn't require re-orienting yourself.

As a verification anchor. When a coaching brochure or third-party education site claims something about NCERT — what's in / what's out / what's coming — cross-check it here. Every claim on this page links back to the official NCERT, CBSE, or NTA source. If a third-party claim contradicts what's here, follow our source link first; we cite the canonical document.

As a navigation hub. Each page links up (to the parent class hub or NCERT root) and across (to adjacent chapters, subjects, or related deletion pages). The hierarchy is designed to support depth-first browsing — start broad, drill down, and pop back up. Use the breadcrumbs at the top of every page to navigate the hierarchy without losing context.

If you're a teacher or counsellor, this page is also designed to print cleanly to a single PDF — no popups, no distracting ads, no required logins.

Beyond NCERT — other free Government of India learning resources

NCERT is the canonical syllabus, but it isn't the only free educational resource the Indian government publishes. Each of the platforms below complements NCERT for a specific use case.

ePathshala (epathshala.nic.in) is the Ministry of Education's digital reader for NCERT books. It hosts the same PDFs as ncert.nic.in but with an enhanced flipbook interface that's easier to read on phones. Use it when you want a screen-friendly reading experience rather than a download. Note: ePathshala does not host any content not also available on ncert.nic.in — both are sourced from the same NCERT-published files.

DIKSHA (diksha.gov.in) is the Ministry of Education's video-and-interactive content platform. It curates chapter-aligned videos (some from NCERT's own YouTube channel, some third-party), interactive quizzes, and 'energised textbook' augmentations — QR codes inside printed NCERT books that link to DIKSHA media. Use DIKSHA when you want video reinforcement of a chapter you've already read; it's not a substitute for the textbook.

Swayam (swayam.gov.in) hosts MOOCs (massive open online courses) from IITs, IIMs, IISc, and other Indian institutions of national importance. Most courses target undergraduates, but some target Class 11-12 with dedicated CBSE-aligned content. Genuinely useful for self-driven Class 11-12 students; the certificates are NPTEL/UGC-recognised.

Swayam Prabha (swayamprabha.gov.in) is a 32-channel DTH education broadcast that runs 24×7. Schedules align with the academic year. Useful for students in low-connectivity areas where streaming video is unreliable.

NCERT Official YouTube (youtube.com/@NCERTOFFICIAL) hosts chapter-aligned video lessons authored by NCERT-empanelled teachers. Free, embeddable, and authoritative — these are the videos we curate on our chapter pages where available.

Editorial policy and how this page is maintained

Every NCERT-related page on GetSchoolsInfo is built from the same editorial policy, summarised here for transparency:

Source-of-truth. All chapter PDFs and rationalisation booklets are hot-linked directly to ncert.nic.in — the official Government of India publisher of NCERT content. We do not host PDFs on our own CDN, we do not redirect through ads, and we do not wrap NCERT links behind a registration wall. If NCERT issues a corrected or updated PDF, the link auto-refreshes from NCERT's CDN — you always get the latest version.

No commercial upsell. We do not sell or promote commercial guidebooks (RD Sharma, Lakhmir Singh, Together with..., Educart, Oswaal, Arihant). For CBSE board preparation, NCERT textbooks plus NCERT Exemplar Problems are sufficient; commercial books are supplementary at best. For JEE / NEET / CUET preparation, coaching modules add problem volume but are not a replacement for NCERT mastery.

Update cadence. Class-level and subject-level pages are reviewed annually before the academic year start (March-April). Chapter-level PDF link health is checked monthly via automated cron. The dateModified field at the bottom of every page reflects the most recent content edit; the inside cover of each NCERT PDF carries the print-edition year.

Verification. Every factual claim on this page can be cross-checked against the official NCERT rationalisation booklet (BookletClass{N}.pdf on ncert.nic.in), the latest CBSE Sample Paper PDF (cbseacademic.nic.in), or the relevant NTA bulletin (NEET/JEE/CUET 2026 syllabus documents). Disagreements between NCERT and NTA are explicitly flagged via our deleted-syllabus reconciliation pages — we do not paper over the gap.
