The Central Board of Secondary Education releases the most latest CBSE Class 9 Science Syllabus 2024-25 on its official website, The syllabus of the CBSE Class 9 Science includes a total of four units such as Matter – Its Nature and Behaviour, Organization in the living world, Motion, force and work, Food, Food Production. Students preparing for the board exams can download the CBSE Class 9 Science Syllabus 2024-25 PDF and prepare accordingly.
CBSE Class 9 Science Syllabus 2024-25
Science, being a compulsory important subject, requires ongoing focused study and practice throughout the year. Physics, Chemistry, and Biology are the three fields of science taught to students in ninth grade.
The CBSE Class 9 Science Syllabus at this grade level is comprehensive, covering a wide range of topics in each of the three disciplines of science. Students in class 9 must thoroughly review the entire syllabus in order to get knowledge that will assist them in efficiently completing their preparation.

Theme: Food
Unit IV: Food Production
- Plant and animal breeding and selection for quality improvement and management; Use of fertilizers and manures; Protection from pests and diseases; Organic farming
CBSE Class 9 Practical Science Syllabus 2024-25
As we know that In the science, practical plays a crucial role. Thus the board also prescribed Class 9 Science practical Syllabus, that should be followed in whole curriculum. The practicals should be conducted alongside the concepts taught in theory classes. Check out the list of experiments in the table below.
| SL No | (LIST OF EXPERIMENTS) |
| 1 | Preparation of: (Unit-I) a) a true solution of common salt, sugar and alum b) a suspension of soil, chalk powder and fine sand in water c) a colloidal solution of starch in water and egg albumin/milk in water and distinguish between these on the basis of
|
| 2 | Preparation of (Unit-I) a) A mixture b) A compound using iron filings and sulphur powder and distinguishing between these on the basis of: (i) appearance, i.e., homogeneity and heterogeneity (ii) behaviour towards a magnet (iii) behaviour towards carbon disulphide as a solvent (iv) effect of heat |
