The subject of science plays a vital role in developing well-defined abilities in the cognitive, affective, and psychomotor domains in children. It enhances a sense of inquiry, creativity, objectivity, and aesthetic sensitivity.

The upper primary stage demands that students should be provided with many opportunities to engage with the processes of science such as observation, recording observation, drawing, tabulation, graph plotting, etc., while the second stage also expects abstraction and quantitative reasoning to occupies a more central place in the teaching and learning of science. Thus, the idea of ​​atoms and molecules being the building blocks of matter appears, as does Newton’s law of gravitation.

The present curriculum is designed around seven broad themes. Meal; Material; the world of living how things work; moving things, people and thoughts; Natural phenomena and natural resources. Special care has been taken to avoid the temptation to add too many concepts than what can be learned comfortably in the given time frame. No attempt has been made to make it comprehensive.

At this stage, while science is still a common subject, subjects of physics, chemistry, and biology begin to emerge. Students should be exposed to practical activities as well as experiences based on the methods of reasoning that are typical of the subject.

Note for the Teachers about CBSE Class 10 Science Syllabus 2022-23

The chapter on Management of Natural Resources (NCERT Chapter 16) will not be assessed in the year-end examination. However, learners can be assigned to read this chapter and encouraged to briefly write down any concepts from this chapter in their portfolio. This may be for internal assessment and credit may be given for periodic assessment/portfolio).

NCERT textbooks present the information in boxes of the entire book. These help the students to achieve conceptual clarity. However, the information given in these boxes will not be evaluated in the examination to be held at the end of the year.
