You will get to know the names and weightage of units to be covered for Term 2. The Class 10 Science Term 2 Syllabus also mentions the list of experiments for practical work and components of internal assessment for term 2. You will also get to know the examination scheme for CBSE Class 10 Science Term 2 Exam 2021-2022.

General Instructions:

1. The total Theory Examinations (Term I+II) will be of 80 marks and 20 marks weightage shall be for Internal Assessment (Term I+II).

2. Internal Assessment - Maximum Marks 10 for each Term:

a. There will be Periodic Assessment that would include: 

• Three periodic tests will be conducted by the school in the entire session. Average of the two periodic tests/marks of best periodic Test conducted in the Term is to be taken for 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.
