CBSE Class 10 Science Syllabus 2021-22

Class 10 Science Syllabus 2021-22: The Central Board of Secondary Education, CBSE divided the current academic year into two terms -1 and 2. The exams for both the terms were decided to be conducted based on the 50% syllabus. This is the perfect time when students should start getting themselves familiarised with the term 2-course curriculum so that they can have enough time for the revision before the CBSE Term 2 Exam. The present syllabus has been designed around seven broad themes viz. Food; Materials; The World of the Living; How Things Work; Moving Things, People and Ideas; Natural Phenomenon and Natural Resources.

Class 10 Science Syllabus 2021-22

Biology, Chemistry and Physics include gaining knowledge about Food, Materials, The World of the 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.
