Checklist of experiences and weighting for the annual review
The CBSE Class 10 Science Practical Syllabus 2022-2023 can be downloaded in PDF here. This syllabus mentions the list of experiments to be carried out throughout the session as well as their weighting for the annual evaluation.
CBSE Class 10 2022-2023 Practical Science Curriculum: Practical work is an important part of the CBSE 10 class science curriculum. It is important for enrichment of material and helps students gain clarity of concept. The CBSE Class 10 Practical Science Curriculum includes experiments from four of the five units given in the Science Curriculum, namely: Chemical Substances – Nature and Behaviour, The Living World, Natural Phenomena and current effects.
- There are a total of 14 experiences mentioned in the program.
- Class CBSE 10 scientific practical work carries 5 points for the annual assessment
Students must learn to perform all of these experiments accurately so that they can achieve full marks in this part of the exam.
