NCERT Solutions

Complete NCERT Solutions for the new Class 9 Science Exploration textbook (CBSE 2026-27, Code 086) — every in-text question across all 13 chapters, spanning Physics, Chemistry, Biology and Earth Science, solved with full reasoning rather than just the final answer. The new textbook weaves Activities, Think It Overs and Explorations through each chapter instead of confining questions to the end, so these solutions are organised to match that same flow — making it easy to find exactly the question your child is stuck on, whichever section of the chapter it falls in.

In-text Questions

Written and checked against the exact 2026-27 CBSE curriculum by Suchita Arora, who brings 13+ years of CBSE Maths and Science teaching experience to every chapter — so the explanations focus on building genuine conceptual understanding, not just supplying an answer to copy down.

Format

How These Solutions Work

The new Exploration textbook is built around curiosity-led learning — Activities, Think It Overs, and Explorations are woven through every chapter, not tucked away at the end. These solutions are built to match that structure.

🔍

Every In-text Question

Activities, Think It Overs, Quick Checks, and Explorations scattered through the chapter — not just the formal Check Your Understanding section at the end.

💡

Reasoning, Not Just Answers

Every solution explains why the answer is correct — the concept behind it — so students can apply the same thinking to a differently-worded question in an exam.

🧩

Added Chapter-wise

Rather than a rushed all-at-once release, each chapter is completed properly — checked, verified and polished — before it goes live here.
