NCERT Solutions for Class 9 Science – Summary of Each Chapter
Chapter 1: Matter in Our Surrounding
This chapter starts by talking about the characteristics of matter such as matter is made up of particles which are extremely small, particles of matter have space between them, particles of matter are continuously moving, particles of matter attract each other etc. It is essential that you understand these properties deeply and can answer conceptual questions based on them. Then the chapter talks about the three states of matter – the solid, liquid and gaseous state and the interconversion between them.
There are a lot of fundamental concepts in this chapter which form the basis of what you will learn later in Class 9 as well as in higher classes, so take this chapter seriously from the beginning!
Chapter 1 Matter in Our Surroundings
Chapter 2: Is Matter Around Us Pure?
Learn the different types of mixtures (solution, suspension and colloids) and their properties well and learn to distinguish between them. Also learn the differences between physical and chemical changes and study the section on elements and compounds well. You will see conceptual questions from these parts on the exams, so study this material (along with the extra problem set) well.
Chapter 2 Is Matter Around Us Pure?
Chapter 3: Atoms and Molecules
This chapter begins by explaining two very important laws – the law of conservation of mass and the law of constant proportions, followed by Dalton’s atomic theory which you need to understand very well. After that you will begin your study on atoms where you will learn about atomic symbols, atomic mass etc. The second half of the chapter deals with molecules, shows you how to write chemical formulae and calculate molecular mass.
This is a very fundamental and important chapter and you will use these concepts throughout your academic career in science. So, make sure the concepts are like second nature to you from the very beginning.
Chapter 4: Structure of the Atom
While studying the structure of the atom it is vital that you thoroughly learn about Thomson’s model, Rutherford’s model and Bohr’s model as you will see questions from these concepts in your exams. The second half of the chapter talks about how electrons are distributed in different orbits, valency, atomic number and mass number, isotopes and isobars.
All concepts in this chapter are equally important, so place equal stress on all of them. Good luck!
Chapter 4 Structure of the Atom
Chapter 5: The Fundamental Unit of Life
This chapter introduces you to the cell and explains the structure of a cell (eukaryotic and prokaryotic) in detail. This is a fundamental chapter in biology which you will need in later classes as well. While all concepts are equally important, learn the concept of osmosis well. You will see questions from it in your exams. Another important concept for your exams is cell division – mitosis and meiosis, so learn it well.
Chapter 5 The Fundamental Unit of Life
Chapter 6: Tissues
This detailed chapter on tissues is important for your exams. The part of meristematic tissue is very important. The part on xylem and phloem is also very important. Learn to distinguish between different types of muscular tissue in animals. You will need to learn the chapter in detail because you will see detailed questions in the exams. The best way to do this is to understand and visualise the concepts first, before you memorise.
Chapter 7: Motion
This chapter introduces you to motion, motion along a straight line, uniform and non-uniform motion, speed, velocity, acceleration, distance-time graphs, velocity-time graphs, the three equations of motion and uniform circular motion. The best way to understand the concepts in this chapter to practise numericals and graph-based questions. Study the equations of motion and graphs in the textbook well, you will see questions from this material in the exams.
Chapter 8: Force and Law of Motion
This chapter introduces the concept of force and balanced and unbalanced forces. The backbone of the chapter is Newton’s three laws of motion, which you must understand thoroughly and be able to solve problems using them. The problems in this chapter many seem hard at first to beginners but with enough practise you will get the hang of them.
Chapter 8 Force and Laws of Motion
Chapter 9: Gravitation
Learn the universal law of gravitation, Kepler’s laws, and the concept of free fall, well. The concepts on buoyancy and Archimedes’ principle are also very important concepts. The best way to learn this chapter is to write down the main concepts and practise numericals based on them. Our solutions and extra materials are an excellent place to start practising.
Chapter 10: Work and Energy
Start by understanding the scientific definition of work and energy. Then understand the concepts of kinetic energy and potential energy and the interconversion between them. The concept of power is also equally important. Studying our solutions to the activities in the chapter is vital in order to develop clear concepts.
Chapter 11: Sound
The concepts of production and propagation of sound (along with wave representation) are extremely important as you will see conceptual questions from these parts in your exams. Understand the characteristics of sound including frequency, amplitude, and speed and practise numericals based on them. The second half of the chapter talks about the reflection of sound and its application in various fields.
Chapter 12: Improvement in Food Resources
The whole chapter on how to increase yield from crops and animals needs to be studied. The different steps to be followed to increase yield are to be noted and memorised. You will see detailed questions from this chapter in your exams. Our solutions and extra problem set are an excellent place to start.
