CBSE Class 9 Science Syllabus 2022-2023: CBSE Class 9th Science Syllabus for the new academic session (2022-23) has been released by the board. The syllabus has been revised as per the annual scheme of assessment. It is a curtailed syllabus, which is around 30% less than that of 2019. Therefore, students should go through the full syllabus and study only the chapters/topics mentioned in the latest syllabus. List of experiments for practical work and details of internal assessment can also be checked below. Link to download the CBSE Class 9 Science Syllabus 2022-23 is also provided here.

Note for the Teachers:
1. The chapter Natural Resources (NCERT Chapter 14) will not be assessed in the year-end examination. However, learners may be assigned to read this chapter and encouraged to prepare a brief write up on any concept of this chapter in their Portfolio. This may be for Internal Assessment and credit may be given for Periodic Assessment/Portfolio.
2. The NCERT text books present information in boxes across the book. These help students to get conceptual clarity. However, the information in these boxes would not be assessed in the year-end examination.
General Instructions for Annual Examination and Internal Assessment:
1. There will be an Annual Examination based on the entire syllabus.
2. The Annual Examination will be of 80 marks and 20 marks weightage shall be for Internal Assessment. 3.For Internal Assessment:
a. There will be Periodic Assessment that would include:
- For 5 marks- Three periodic tests conducted by the school. Average of the best two tests to be taken that will have a weightage of 05 marks towards the final result.
- For 5 marks- Diverse methods of assessment as per the need of the class dynamics and curriculum transaction. These may include - short tests, oral test, quiz, concept maps, projects, posters, presentations and enquiry based scientific investigations etc. and use rubrics for arguing them objectively. This will also have a weightage of 05 marks towards the final result.
b. Practical / Laboratory work should be done throughout the year and the student should maintain record of the same. Practical Assessment should be continuous. There will be weightage of 5 marks towards the final result. All practicals listed in the syllabus must be completed.
c. Portfolio to be prepared by the student- This would include classwork and other sample of student work and will carry a weightage of 5 marks towards the final results.
