BharatNotes About This Book
Exploration is the new Science textbook for Class IX (Grade 9), introduced under NEP 2020 / NCF-SE 2023 for the 2026-27 session. It replaces the older single "Science" textbook and marks the start of the secondary stage (Grades 9-12). Digital editions were released by NCERT in April 2026 (First Edition, April 2026; ISBN 978-93-5729-567-3).
The title Exploration means "investigating the unknown by observing, posing questions, and experimenting to understand and discover the world around us." The book integrates physics, chemistry, biology, and earth science into 13 connected chapters, deliberately blurring subject boundaries so that real problems (climate change, medicines, sustainable technology) are seen to need many disciplines at once.
Key features of the new approach:
- Activity-based and inquiry-driven — every chapter is built around doing, not memorising
- New signposted features: Think It Over, Pause and Ponder, Threads of Curiosity, Ready to Go Beyond, Bridging Science and Society, Think as a Scientist, Meet a Scientist, At a Glance, and Revise, Reflect, Refine
- Explicit Indian scientific contributions (rootedness, per NEP 2020) — from Meghnad Saha to modern institutions
- QR codes in each unit linking to interactive digital resources on DIKSHA/ePathshala

How to Use This Book for UPSC
Exploration (Class IX Science) is a foundation text, not a directly-tested source — UPSC rarely lifts a question straight from a Class IX chapter, but these concepts underpin dozens of Prelims questions and the GS3 (Science & Technology / Environment) syllabus. Class IX is where school science turns abstract (atoms, forces, cells, energy), so it is the natural place to rebuild fundamentals before layering current affairs on top.
Smart-study approach:
- Read for concepts, not memorisation — grasp the First Principles in each chapter, since application beats recall in general-science Prelims.
- Follow the "PART 3 — UPSC Integration" in each chapter — it maps the school concept to the actual exam (GS3 themes, schemes, current S&T like ISRO/DAE/nuclear energy, biodiversity).
- Use the Revision Capsule (Hard Facts / Confused Pairs / PYQ Pattern) for last-mile revision.
- Cross-link to current affairs — pair each concept with the latest data (via Ujiyari) so a static concept becomes an exam-ready, date-stamped fact.
Who should read this: beginners rebuilding fundamentals, and revisers who want a fast, concept-first refresher of the school-level science the exam quietly assumes you know.
