CBSE Class10 Science Term 2 Syllabus (2021-2022) (PDF). Check course structure and criteria for internal assessment. Exam scheme

a. There will be Periodic Assessment that would include:

• Three periodic tests will be conducted by the school in the entire session. The average of the two periodic tests/marks of the best periodic Tests conducted in the Term is to be taken into consideration.

• 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, enquiry based scientific investigations etc.

b. Subject Enrichment in the form of Practical/Laboratory work should be done throughout the year and the student should maintain record of the same. Practical Assessment should be continuous. All practicals listed in the syllabus must be completed. c. Portfolio to be prepared by the student- This would include class work and other sample of student work.
