Top Tips To Prepare For 9th Class Science Exam

-

Using observation and experimentation, scientific laws are laid down. Each law is rooted in and stems from logical and mathematical proof. Many scientists have contributed immensely to revolutionizing our knowledge of the universe. Advancements have been made in the field of physics, chemistry, and biology alike. A few decades ago, even the nucleus of a cell had not been discovered. Now, we have the machinery to map the entire genome of a human using certain techniques. It is safe to say that science has progressed by leaps and bounds. The advanced tech we possess today is paving the path for future generations.

There is no other subject that can fascinate the human mind more than Science if one knows the right way to study it. Science subjects are termed difficult simply because there is a lot of information that needs to be remembered. If you can think rationally and are capable of grasping concepts quickly, science is the right fit for you. Students can easily score very good marks in science all while enjoying the subject. Class 9 Science lays down the foundation for several topics that you will encounter in higher classes too. It also helps you build a base for future competitive exams that you may wish to sit for.

Class 9 Science Syllabus

1
Unit I: Matter – Its Nature & Behaviour

Chapter I: Definition of Matter

Here, we deal with the various states of matter and their respective definitions and characteristics. The change of state by absorption or evaporation of heat is also discussed.

Chapter II: Nature of Matter

Students are familiarized with elements, compounds, and mixtures. These mixtures are divided into homogeneous and heterogeneous mixtures. Another classification can be done on the basis of colloids and suspensions.

Chapter III: Particle nature, basic units

Certain laws are mentioned along with the method to calculate atomic and molecular masses.

Chapter IV: Mole Concept

Students are taught about moles and Avogadro’s number.

Chapter V: Structure of atom

Various models explaining the structure of an atom are proposed. In addition to this, electrons are also explained in detail by mentioning orbitals and their multiple valent states.

Unit II: Organisation in the Living World

Chapter I: Cell – Basic Unit of life

A cell is defined as the structural and functional unit of life that can be further divided into prokaryotic and eukaryotic cells. Multicellular organisms are mentioned along with the cell components they possess like a cell membrane or a cell wall. Some common cell organelles like the chloroplast, mitochondria, vacuoles, endoplasmic reticulum and the Golgi apparatus are also mentioned in brief.

Chapter II: Tissues, Organs, Organ System, Organism

The definition of tissue is provided. Students are given an insight into the four types in animals and meristematic and permanent tissues in plants.

Chapter III: Biological Diversity

Living organisms are classified into Bacteria, Thalophyta, Bryophyta, Pteridophyta, gymnosperms, and Angiosperms according to the characteristics they possess. Animals are also classified. Non-chordates are divided up into phyla and chordates up to classes.

Chapter IV: Health and Diseases

Various infectious and non-infectious diseases are mentioned along with their preventive methods and treatment protocols.

3
Unit III: Motion, Force and Work

Chapter I: Motion

Basics like distance, displacement, velocity, and acceleration are explained. Circular motion is represented graphically.

Chapter II: Force and Newton’s Laws

Newton’s famous laws of motion are taught. Concepts linking the force produced, the inertia of a body, momentum, and acceleration are also taught. Questions are frequently asked on action and reaction forces.

Chapter III: Gravitation

The universal law of gravitation is laid out along with its implications upon mass and weight. Freefall is also discussed.

Chapter IV: Floatation

Thrust and pressure are explained using Archimedes’ principle. Using these examples, the concept of buoyancy is also mentioned in brief. An elementary idea of relative density is provided.

Chapter V: Work, energy and power

Work done by a force is explained. Kinetic and potential energies are dealt with using the law of conservation of energy.

Chapter VI: Sound

The nature of sound and its mechanism of propagation in various media is explained. Here, we also discuss the speed of sound and the range of hearing in humans. Moreover, new topics like ultrasound, echo, and SONAR are also introduced. The auditory aspect of the structure of the human ear is outlined.

4
Unit IV: Our Environment

Chapter I: Physical Resources

The role various natural resources play in our lives is highlighted. Methods of conservation are discussed along with the rising need to go green.

5
Unit V: Food Production

Chapter I: Plant and Animal

This chapter is all about plant and animal breeding and selection for an improvement in the quality of the food we consume today. The use of fertilizers and various manures is outlined. An elementary idea of organic farming is introduced.

How To Prepare For Class 9 Science Exam

•           Find out the exam pattern followed by your school – The marking system varies from school to school in class 9. It is best to find out from your teachers what the format of your paper will be like.

•           Make a proper study schedule – The importance of a proper and efficient study schedule cannot be stressed enough. Make sure you formulate a decent timetable and then try to abide by it.

•           Solve lots of questions – As the saying goes, practice makes a man perfect. Solve as many questions as possible in Science.

•           Stick to NCERT – For CBSE Class 9 Science, NCERT is sufficient. Do not try to buy and hoard multiple other reference books. Read your textbook twice or thrice to retain all the information it contains.

•           Refer to NCERT SolutionsNCERT solutions help clear all your basics and make you understand the subject better. Make sure to refer to them whenever you are stuck or have doubts.

•           Do not stress – Once you figure out how to deal with science subjects, you will have no difficulty cruising through your school exams. However, do not compromise on getting proper rest and sleep.
