How Many Chapters Are in the NCERT Class 9 Science Book in Hindi?
The new NCERT Class 9 Science book (Exploration) has 13 chapters, replacing the earlier 15-chapter book from the 2026-27 session onward. CBSE school and board exams from 2026-27 are based on this new book — confirm with your school which edition you're currently following, or check the official CBSE website.
Which Chapters Are Likely Most Important for Exams?
Because this is the first year of the new book, there's no multi-year CBSE exam pattern to draw on yet. Based on chapter weightage in the old syllabus and the topics NCERT has retained or expanded, these areas are likely to carry significant marks: Cell (Ch. 2), Tissues (Ch. 3), Motion and Forces (Ch. 4, 6), Atomic Foundations (Ch. 9), and Work/Energy (Ch. 7). We'll update this section with confirmed CBSE weightage once the first sample papers for 2026-27 are released.

Frequently Asked Questions
Is the NCERT Class 9 Science Book in Hindi available as a free PDF?
Yes. The NCERT Class 9 Science Book in Hindi — the new Exploration edition for 2026-27 — is available as a free, chapter-wise PDF on eSaral, with all 13 chapters. No login or sign-up is required.
How many chapters are in the NCERT Class 9 Science Book in Hindi?
The NCERT Class 9 Science Book in Hindi has 13 chapters in its 2026-27 edition, down from 15 in the earlier book. It covers Physics, Chemistry, Biology, and a new Earth Science chapter.
Is the old 15-chapter NCERT Class 9 Science Book in Hindi still valid for 2026-27?
No. From the 2026-27 academic session, CBSE schools use the new 13-chapter Exploration edition of the NCERT Class 9 Science Book in Hindi. If your school hasn't switched yet, check with your teacher, as some schools transition mid-year.
Why did NCERT reduce the number of chapters in the Class 9 Science book?
The new book follows the NCF-SE 2023 framework (aligned with NEP 2020), which favors fewer, more integrated chapters connecting Physics, Chemistry, Biology, and Earth Science, instead of separate subject-wise chapters. Reproduction shifted down from Class 10, and Earth Science was added as an entirely new strand.
What happened to Gravitation and Why Do We Fall Ill in the new book?
Both chapters have been removed from the Class 9 syllabus in the 2026-27 revision. Neither is part of the new 13-chapter NCERT Class 9 Science Book in Hindi.
Which chapters in the new NCERT Class 9 Science Book in Hindi are most important for exams?
Since this is the first year of the new book, there's no multi-year CBSE exam pattern to go by yet. Based on the old syllabus and the emphasis NCERT has placed on certain topics, Cell (Ch. 2), Tissues (Ch. 3), Motion and Forces (Ch. 4, 6), and Atomic Foundations (Ch. 9) are likely to carry significant marks.
Can I download individual chapters of the NCERT Class 9 Science Book in Hindi, or only the full book?
Both. eSaral's chapter-wise table above lets you download any single chapter directly, and you can also download the complete NCERT Class 9 Science Book in Hindi as one combined file, sourced from the official NCERT curriculum, right here on eSaral.
Does eSaral provide solutions along with the NCERT Class 9 Science Book in Hindi?
Yes. Alongside the book PDF, eSaral provides free NCERT Solutions for Class 9 Science, with chapter-wise answers to in-text and exercise questions, so you can check your work after solving each chapter yourself.
How is the new NCERT Class 9 Science Book in Hindi different from the old one?
The new edition merges Physics, Chemistry, and Biology into one integrated sequence instead of three separate sections, drops three chapters (Gravitation, Why Do We Fall Ill, Improvement in Food Resources), moves Reproduction down from Class 10, and adds a completely new Earth Science chapter.
Does the NCERT Class 9 Science Book in Hindi help with JEE and NEET foundation?
Yes. Chapters on Motion, Forces, Work and Energy build directly into JEE Physics, while Cell, Tissues, and Reproduction build into NEET Biology. eSaral's Class 9 foundation courses are structured around exactly this progression, so concepts learned from the NCERT book connect directly to Class 11–12 topics rather than being taught in isolation.
