Science plays a crucial role in shaping analytical and reasoning skills in students. The CBSE Science syllabus for Classes 9 and 10 (2025-26) aims to develop scientific temper and a deeper understanding of natural phenomena. This comprehensive guide will cover the detailed syllabus, exam structure, practicals, and study tips for students to excel.
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.
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 temptation of adding too many concepts than 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.
The CBSE Class 10 Science syllabus consists of five units:
| Unit No. | Unit Name | Marks |
| I | Chemical Substances – Nature and Behaviour | 25 |
| II | World of Living | 25 |
| III | Natural Phenomena | 12 |
| IV | Effects of Current | 13 |
| V | Natural Resources | 5 |
| Total | 80 |
Here is the detailed blueprint for CBSE Class 10 Science for the academic year 2025-26. The marks are divided into five types of questions: Assertion & Reason, Picture-Based MCQs, Multiple Choice Questions, Source/Case-based Questions, and Subjective Questions.
