CBSE Class 10 Science Syllabus 2023-24 PDF with Important Resources

CBSE Class 10 Science Syllabus 2023-2024: The CBSE syllabus of Class 10 Science for the current academic session 2023-24 is available here in a detailed format. The latest CBSE Class 10 Science Syllabus is divided into five broad themes viz. Materials, The World of The Living, How Things Work, Natural Phenomenon and Natural Resources. The board had reduced the CBSE Class 10 Science Syllabus by 30% for the last academic session and the same deletion in the syllabus is to be retained for the current academic session as well. Thus, the deleted parts of the syllabus will not be considered for assessment in AY 2023-24. Check below the link to know the deleted CBSE syllabus of Class 10 Science and also check and download the complete syllabus of CBSE Class 10 Science from this article.

General instructions to be noted for CBSE Class 10 Science Curriculum 2023-24 are:

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 will include:

• Three periodic tests are to be 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.
• 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.
