CBSE Class 9 Science Syllabus 2026

The Central Board of Secondary Education (CBSE) has prescribed the Class 9 Science syllabus for the academic session 2026–27 to develop students’ scientific understanding, practical skills, critical thinking and problem-solving abilities. The curriculum covers key concepts related to living organisms, matter, motion, force, work, sound and Earth as a system.

Students should refer to the official CBSE curriculum document applicable to their school, as CBSE provides separate Science curricula for Standard and Advanced levels.

CBSE Class 9 Science Syllabus 2026: Overview

The CBSE Class 9 Science curriculum is divided into four major units. Students study theoretical concepts along with practical activities and experiments to understand scientific principles and their real-life applications.
