CBSE Class IX syllabus 2024-25 : A roadmap for both students and teachers
A syllabus is like a roadmap for both students and teachers. Here's why it's important:

1. Guidance: It outlines what students will be learning throughout the year, giving them a clear path to follow. This helps students stay focused and understand what's expected of them.
2. Organization: A syllabus helps teachers organize their lessons and materials. It ensures that they cover all the necessary topics and meet educational standards.
3. Transparency: It provides transparency to students about course expectations, grading criteria, and classroom policies. This helps create a fair and consistent learning environment.
4. Accountability: A syllabus holds both students and teachers accountable for their roles in the learning process. Students know what they need to do to succeed, and teachers are responsible for delivering the curriculum effectively.
5. Communication: It serves as a communication tool between teachers, students, and parents. It can include contact information, office hours, and other important details to facilitate communication throughout the school year.
6. Preparation: A syllabus helps students and teachers prepare for lessons, assessments, and exams. It gives them a clear overview of the topics to be covered and allows them to plan accordingly.
Overall, a syllabus is essential for creating a structured and productive learning environment where everyone knows what to expect and how to succeed.
Here is Class IX and X Science syllabus : -
SCIENCE
(Code No. 086)
Classes: IX and X (2024-25)
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.
General Instructions:
1. There will be an Annual Examination based on the entire syllabus.
2. The Annual Examination will be of 80 marks and 20 marks weightage shall be for Internal Assessment.
3. For Internal Assessment:
a. There will be Periodic Assessment that would include:
- For 5 marks- Three periodic tests conducted by the school. Average of the best two tests to be taken that will have a weightage of 05 marks towards the final result.
- For 5 marks- Diverse methods of assessment as per the need of the class dynamics and curriculum transaction. These may include - short tests, oral test, quiz, concept maps, projects, posters, presentations and enquiry based scientific investigations etc. and use rubrics for arguing them objectively. This will also have a weightage of 05 marks towards the final result.
b. Practical / Laboratory work should be done throughout the year and the student should maintain record of the same. Practical Assessment should be continuous. There will be weightage of 5 marks towards the final result. All practicals listed in the syllabus must be completed.
c. Portfolio to be prepared by the student- This would include classwork and other sample of student work and will carry a weightage of 5 marks towards the final results.
