SEBA Board Class 9 Science Syllabus

SEBA Board Class 9 Science syllabus is prescribed by the Board of Secondary Education Assam commonly known as SEBA. The board incorporates subject professionals who design the syllabus and revise it on regular intervals. This continuous process has brought significant changes over the years. SEBA moved a step ahead by imposing Science Practicals for Class 9. As a consequence of this extra dimension in the curriculum, science learning has become more engaging among students. Thus, this autonomous body succeeded in achieving substantial progress by attaining greater scientific and technological literacy.

SEBA Board Class 9 Science syllabus comprises of theory as well as practical. concepts covered under theory are – states of matter, atoms, molecules and their structures, cells, tissues, living organisms, motion force, laws of motion, work and energy, gravitation, sound etc. Science practical are designed in a way that concreats the concepts they study in theory part.

Refer the table given below for detailed SEBA Board Class 9 Science Syllabus prescribed by the board:

Sl.No Chapters Key concepts Marks
1 Matter in our surroundings Cooling by evaporation. Absorption of heat.

All things occupy space, possess mass. Definition of matter.

Solid, liquid and gas; characteristics-shape, volume, density; change of state-melting, freezing,

Evaporation, condensation, sublimation.

2 Is matter around us pure Elements, compounds and mixtures. Heterogeneous and homogeneous mixtures. Colloids and suspensions

Equivalence -that x grams of A is chemically not equal to x grams of B.

3 Atoms and molecules Particle nature, basic units; atoms and molecules. Law of constant proportions. Atomic and molecular masses.

Mole concept. Relationship of mole to mass of the particles and numbers. Valency. Chemical formulae of common compounds.

4 Structure of the atom Atoms are made up of smaller particles: electrons, protons, and neutrons. These smaller particles are present in all the atoms but their numbers vary in different atoms. Isotopes and isobars. 06
5 The fundamental unit of life Cell as a basic unit of life; Prokaryotic and eukaryotic cells, multicellular organisms; cell membrane and cell wall, cell organelles: chloroplasts, mitochondria, vacuoles, ER, Golgi Apparatus; nucleus, Chromosomes – basic structure, number. 05
6 Tissues Tissues, organs, organ systems, organism.

Structure and functions of animal and plant tissues (four types in animals; meristematic and permanent tissues in plants.)

7 Diversity in living organisms Diversity of plants and animals-basic issues in scientific naming, Basis of classification, Hierarchy of categories/groups, Major groups of plants (salient features) (Bacteria, Thallophyta, Bryophyta, Pteridophyta, Gymnosperms and Angiosperms.) Major groups of animals (salient features) (Non-chordates up to phyla and Chordates up to classes.) 07
8 Motion Motion-displacement, velocity; uniform and non Uniform motion along a straight line, acceleration, distance-time and velocity time graphs for uniform and uniformly accelerated motion, equation of motion by graphical method; elementary idea of uniform circular motion 07
9 Force and Laws of Motion Force and motion, Newton’s laws of motion: Inertia of a body inertia and mass, momentum, force and acceleration. Elementary idea of conservation of momentum, action and reaction forces. 08
10 Gravitation Gravitation; universal law of gravitation, the Force of gravitation of the earth (gravity), acceleration due to gravity; mass and weight; free fall. 07
11 Work and energy Work done by a force, energy, power; kinetic and potential energy; law of conservation of energy

Floating bodies:

Thrust and pressure. Archimedes’ principle, buoyancy, elementary idea of relative density

12 Sound Nature of sound and its propagation in various media, speed of sound, range of hearing in humans, ultrasound, reflection of sound, echo and sonar, Structure of the human ear (auditory aspect only). 06
13 Why do we fall ill Health and its failure. Disease and its causes. Diseases caused by microbes and their prevention-Typhoid, diarrhoea, malaria, hepatitis, rabies, AIDS, TB, polio; pulse polio programme. 05
14 Natural resources Physical resources: air, water, soil, air for respiration, for combustion, for moderating temperatures, movements of air and its role in bringing rains across India. Air, water and soil pollution (brief introduction).

Holes in the ozone layer and the probable damages. Biogeochemical cycles in nature: water, oxygen, carbon, nitrogen

15 Improvement in Food resources Plant and animal breeding and selection for quality improvement, use of fertilizers, manures; protection from pests and diseases; organic farming. 05
