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 performed throughout the session along with their weightage for the annual assessment.

CBSE Class 10 Science Practical Syllabus 2022-2023: Practicals are a prominent part of the CBSE Class 10 Science curriculum. They are important for subject enrichment and help students gain the concept clarity. CBSE Class 10 Science Practical Syllabus includes experiments from four out of the five units given in the Science syllabus which are: Chemical Substances-Nature and Behavior, World of Living, Natural Phenomena and Effects of Current.

  • There are a total of 14 experiments mentioned in the syllabus.
  • CBSE Class 10 Science Practicals carry 5 marks for the annual assessment

Students must learn to perform all these experiments accurately so that they can score full marks in this part of the examination.
