CBSE Class 10 Science Term I Syllabus 2021-2022 (Revised)

Here is the CBSE Class 10th Science Syllabus 2021-2022. You can download the revised/rationalized syllabus and prepare for the Term 1 Board Exam, which will be held in November-December 2020.

The CBSE Class 10 Science Revised syllabus for the current academic session 2021-2022 has been released by the board via its official website. The Science syllabus has been divided by the Board into two terms: Term 1 and 2. Here is the CBSE Class 10 Science Curriculum for Term 1. This revised syllabus must be read by students before they begin preparations for the CBSE Class 10 Board Exam 2021-2022. The Term 1 Exam will take place in November-December.

General Instructions

1. The Theory Examinations (Term II+II) total will be 80 marks. 20 marks weightage shall go to Internal Assessment (Term II+II).

2. Internal Assessment – Maximum Marks 10, for each Term

a. There will be a periodic assessment that would include:

The school will conduct three periodic tests during the whole session. The average of the two periodic tests/marks for the best periodic Tests conducted during the Term will be considered.

* Different methods of assessment depending on the needs of the class dynamics or curriculum transaction. These include: short tests, oral tests, quizzes, quizzes, quizzes, concept maps and posters, presentations, inquiry-based scientific investigations, etc.

b. b. Subject enrichment should be continued throughout the year through practical/laboratory work. The student should keep a record of this. Continuous assessment should be done in practical. You must complete all practicals as listed in the syllabus. c. The student must prepare a portfolio. This would include sample work from students.
