CBSE Class 9 Science Syllabus For 2023-24 (Revised)

The Central Board of Secondary Education (CBSE) has released the revised 9th class Science syllabus for the upcoming academic session for the year 2023-24. The syllabus provides students with a strong foundation in basic science concepts and skills. The topics covered in the syllabus include Nature and Behaviour of Matter, Organization in the Living World, Motion, Force and Work, and Food Production. 

The science syllabus for class 9 is designed in such a way that it forms the foundation for the all-important board exams and competitive exams in the upcoming years. Without mastering these concepts first, you will not be able to ace those exams. For example, when it comes to Carbon and its Compound in class 10, you learn the concepts of the Structure of Atoms and Molecules in class 9. This means, that if your science concepts are strong in class 9 itself, class 10 gets much easier!

CBSE Science Syllabus For Class 9 follows the Class 9 science syllabus of NCERT.

Chapter 7: Motion 

Motion is all around us, from moving cars to flying aeroplanes. Motion can have different features like speed, direction, acceleration, etc. In this chapter, we will understand these features in detail and see how they can help us predict the future of these moving things.

• Distance and Displacement
• Velocity 
• Uniform and Non-Uniform Motion Along a Straight Line
• Acceleration
• Distance-Time and Velocity-Time Graphs for Uniform Motion and Uniformly Accelerated Motion 
• Elementary Idea of Uniform Circular Motion

Chapter 8: Force and Newton’s Laws

In Physics, force is defined as a push or pull on an object with mass that causes it to change its velocity. In this chapter of the CBSE class 9 science syllabus, you will learn about three basic laws governing the motion and forces we observe in this universe. These laws are commonly known as Newton’s laws of motion.

• Forces
• Inertia of a Body 
• Inertia and Mass 
• Momentum
• Force and Acceleration

Chapter 9: Gravitation 

In previous chapters, you learned about the motion of objects and force as the cause of motion. You also learned that a force is needed to change the speed or the direction of motion of an object. In this chapter, you will be introduced to the concept of gravitation and the universal law of gravitation. You will also learn the motion of objects under the influence of gravitational force on the earth.

• Gravitation
• Universal Law of Gravitation 
• Force of Gravitation of the Earth (Gravity)
• Acceleration Due to Gravity 
• Mass and Weight
• Free Fall

Chapter 10: Floatation 

The tendency of an object to rise up to the upper levels of the fluid or to float on the fluid surface is known as floatation.

The phenomenon of floatation totally depends on the density of the object placed in the fluid and the density of the fluid in which it is placed. This chapter describes the well-known Archimedes Principle of floatation. You will further learn about thrust, pressure, and buoyancy.

• Thrust and Pressure
• Archimedes’ Principle 
• Buoyancy

Chapter 11: Work, Energy and Power

In the previous few chapters, you learned about ways of describing the motion of objects, the cause of motion, and gravitation.
