CBSE Class 10 Science Syllabus 2022-23

Class 10 Science Syllabus 2022-23: The Central Board of Secondary Education, CBSE has released the detailed Class 10 Science Syllabus for the academic session 2022-23. This is the perfect time when students should start getting themselves familiarised with the board exam curriculum so that they can have enough time for the revision before the CBSE Board Exam. There are 5 units included in the Class 10 Science Syllabus 2022-2023. This year CBSE will conduct a single annual examination and no term-wise scheme is to be followed. 

Class 10 Science Syllabus 2022-2023

Biology, Chemistry and Physics include gaining knowledge about Food, Materials, The World of Living, How things work, Moving things, People and Ideas, Natural Phenomenon and Natural Resources. The Focus is on knowledge and skills to develop a scientific attitude and to use and apply such knowledge for improving the quality of life. The subject of Science plays an important role in developing well-defined abilities in cognitive, affective and psychomotor domains in children. It augments the spirit of enquiry, creativity, objectivity and aesthetic sensibility.
