CBSE Class 9 Science Syllabus 2024-25, Download PDF

The Central Board of Secondary Education released the most latest Class 9 Science Syllabus for the current academic year, 2024–25. To perform well in examinations and yearly exams, students must completely review the CBSE Class 9 Science Syllabus 2025 and devote adequate attention to each topic discussed in it. Scroll down the page for a brief overview of the chapters included in the CBSE Class 9 Science Syllabus 2024-25.

CBSE Class 9 Science Syllabus 2024-25

The topics covered in the CBSE class 9 syllabus 2024–25 establish the foundation for the ideas that students will learn in more advanced courses. Physics, Chemistry, and Biology are the three fields of science taught to students in Class 9.

For students in this level of education, the CBSE Class 9 Science Syllabus is comprehensive and includes a wide range of subjects in all three branches of science. As a result, they must understand the core concepts stated in the CBSE Class 9 syllabus. Check out the whole theoretical syllabus as well as the list of experiments required for the CBSE Class 9 Science practical assessment.

Science Class 10 Syllabus 2025

The CBSE Class 9 Science Syllabus 2025 allows students to efficiently plan their study time. The curriculum consists of four units, the names of which, together with the weightage allotted for the annual examination, are as follows:

CBSE Class 9 Science Syllabus 2025 Unit Wise

CBSE administers an 80-mark annual theory exam for Class 9 All subjects with an additional 20 marks for internal assessments. Students must be aware that the Annual Examination will be based on the full Class 9 Science Syllabus 2024-25. As a result, students must efficiently complete all four units included in the Class 12 Science syllabus.

Theme: Food

Unit IV: Food Production

Plant and animal breeding and selection for quality improvement and management; Use of fertilizers and manures; Protection from pests and diseases; Organic farming.

Class 9 Science Syllabus for Practicals

Practicals should be conducted alongside the concepts taught in theory classes.

(LIST OF EXPERIMENTS)
