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 2022-2023 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.

General Instructions:

  1. The total Theory Examinations (Term I+II) will be 80 marks and 20 marks weightage shall be for Internal Assessment (Term I+II).
  2. Internal Assessment - Maximum Marks 10 for each Term:
  3. There will be a Periodic Assessment that would include:
  4. Three periodic tests will be conducted by the school in the entire session. The average of the two periodic tests/marks of best periodic Tests conducted in the Term is to be taken into consideration.
  5. 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, inquiry-based scientific investigations, etc.
  6. Subject Enrichment in the form of Practical/Laboratory work should be done throughout the year and the student should maintain a record of the same. Practical Assessment should be continuous. All practicals listed in the syllabus must be completed.
  7. Portfolio to be prepared by the student- This would include classwork and another sample of student work.
