Check List of Experiments and Weightage for Annual Exam
CBSE Class 10 Science Practical Syllabus 2022-2023 can be downloaded in PDF here. This syllabus mentions the list of experiments to be done throughout the session along with their weightage for annual assessment.
CBSE Class 10 Science Practical Syllabus 2022-2023: Practicals are a major part of CBSE Class 10 Science syllabus. They are important for subject enrichment and help students gain concept clarity. CBSE Class 10 Science practical syllabus consists of experiments from four of the five units given in the Science syllabus which are: Chemical Matter-Nature and Behavior, World of Life, Natural Phenomenon and Effects of the Present.
- A total of 14 experiments are mentioned in the syllabus.
- CBSE Class 10 Science Practicals are of 5 marks for Annual Assessment
Students must learn to do all these experiments correctly so that they can score full marks in this part of the exam.
