CBSE Class 10 Science Syllabus Term Wise for 2023-24: Students who are preparing for the CBSE Class 10 board exam must be aware of CBSE Syllabus for Class 10 Science. The officials of CBSE design the academic CBSE Class 10 Syllabus 2023-24 for all subjects. Having a detailed knowledge of the CBSE Class 10 Syllabus for Science will ensure students cover the entire syllabus without skipping any chapter or concept.

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.

Upper primary stage demands that a number of opportunities should be provided to the students to engage them with the processes of Science like observing, recording observations, drawing, tabulation, plotting graphs, etc., whereas the secondary stage also expects abstraction and quantitative reasoning to occupy a more central place in the teaching and learning of Science. Thus, the idea of atoms and molecules being the building blocks of matter makes its appearance,as does Newton’s law of gravitation.

CBSE Class 10 Science Exam Pattern 2023-24

CBSE Class X Science Syllabus 2023-24

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. Special care has been taken to avoid the temptation of adding too many concepts that can be comfortably learnt in the given time frame. No attempt has been made to be comprehensive.

At this stage, while science is still a common subject, the disciplines of Physics, Chemistry and Biology begin to emerge. The students should be exposed to experiences based on hands-on activities as well as modes of reasoning that are typical of the subject.
