CBSE Class 9 Science Syllabus 2023-24

CBSE Science Syllabus Class 9 Term (1 & 2) 2023-24 Exam

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 

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 9 SCIENCE 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

Students will have the opportunity to create a strong foundation for their understanding of complex scientific concepts if they thoroughly study the topics that are included in the CBSE 9 SCIENCE SYLLABUS.

The CBSE has released the CLASS 9 SCIENCE SYLLABUS for the year 2022.. Before starting the preparation for the science exam , students are required to review the entire curriculum. This will help students get comprehensive information regarding the examination, including the chapter list, and the weightage of each individual unit. Students can access the syllabus from the website of Extramarks.

An Overview of the CBSE Class 9 Science Syllabus

In order to facilitate learning, the whole CBSE Science syllabus for Class 9 has been split into two terms: Term 1 and Term 2. Each of the two terms will cover fifty percent of the total course content. The first exam will be objective, while the second exam will be a mix of objective and subjective questions.

The CBSE Class 9 Science syllabus covers a large amount of content. However, if you start early enough and put in the necessary effort, you should have no trouble mastering the subject and performing well in the exam. If you have a firm grasp of the fundamental ideas, you will be in a better position to perform well in the exam. Also, the CBSE REVISION NOTES can be extremely helpful especially during the final stages of preparation. 

Because of the continuing COVID-19 epidemic, the curriculum has been updated by the official authorities of the CBSE. This choice is made to relieve the stress that is caused by assigning students with such a lengthy course.

The CBSE Science curriculum for Class 9 is basically divided into 4 different units:

These include (i) Matter – Nature and Behaviour: definition, nature of matter, nature of particles, structure of atoms, (ii) Organisation in the Living World: cell, tissues, organs, organ system, organism, biological diversity, health and diseases, (iii) Motion, Force and Work: motion, force and Newton’s laws, gravitation, floatation, work, energy and power, sound, (iv) Our Environment: physical resources, biogeochemical cycles in nature.

Students who want to prepare for the CBSE Class 9 syllabus in the most effective way possible may find the following recommendations helpful:

(i) Create a schedule for yourself so that you can keep track of which chapters require your attention and how you would start working on them.

(ii) Form revision notes for yourself so that you may go back to them for reviewing all of the chapters before your tests.

(iii) Start preparing at an early stage to avoid any kind of hassle during the final stage of examinations..

(iv) Underline key points to ensure that you don’t miss them when you’re flipping through the pages.

(v) To get good grades in exams students must refer to multiple study resources, practice a lot of questions and stick to a study schedule and follow it religiously to come out with flying colours. 

The Central Board of Secondary Education (CBSE) has compiled a list of recommended reading material, which can be referred to in order to learn all of the required Science topics for Class 9.

(i) Science Textbook for Class IX by NCERT Publication: Students who read this book will have an easier time preparing for the theoretical section of the Science curriculum.

(ii) The book “Assessment of Practical Skills in Science-Class IX-CBSE Publication” will assist the student in preparing for the practical examination that will be administered.

(iii) Laboratory Manual for Science, Class IX, NCERT Publication: Students will find that this book is helpful in preparing for laboratory experiments as well as writing manuals for such experiments.

(iv) Exemplar Problems for Class IX, which is a publication by the NCERT, is a book that can assist students in finding answers to questions on the topics covered in the curriculum.
