CBSE Syllabus for Class 9 Science 2024-2025

CBSE Class 9 Science Syllabus

Progressing onto this stage Science has expanded its horizon to become one of the core subjects for the students. The topics explore the various aspects of science in-depth to familiarize students with the three branches of science this year forth. The units put a limelight on the precursors of the next academic year’s curriculum. Syllabus The curriculum for the academic year 2024-2025 as per the NCERT guidelines is divided into 2 terms, 3 units each. Each Unit has a certain amount of chapters according to the relatability of the topics.
