IGNOU-UNESCO Science Olympiad Class IX Science Syllabus | IGNOU-UNESCO Science Olympiad Class IX Syllabus
CBSE (INDIA) CLASS IX (Chemistry, Physics, Biology)
CLASS IX- SCIENCE SYLLABUS Units
I. Matter – ITS nature and behaviour
II. Organisation in living world
III. Motion, Force and Work
Unit I: MATTER – NATURE AND BEHAVIOUR
Definition of matter; solid, liquid and gas; characteristics – shape, volume, density; change of state-melting (absorption of heat), freezing, evaporation (Cooling by evaporation), condensation, sublimation.
Nature of matter : Elements, compounds and mixtures. Heterogenous and homogenous mixtures, colloids and suspensions.
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 formula of common compounds
Structure of atom : Electrons, protons and neutrons; Isotopes and isobars.
Unit II: ORGANIZATION IN THE LIVING WORLD
(45) Periods
BiologicalDiversity : Diversity of plants and animals – basic issues in scientific naming, basis of classification. Hierarchy of categories / groups, Major groups of plants (salient features) (Bacteria, Thalophyta, Bryo phyta, Pteridophyta, gymnosperms and Angiosperms). Major groups of animals (salient features) (Non-chordates upto phyla and chordates upto classes).
Cell- Basic Unit of life : Cell as a basic unit of life; prokaryotic and eukaryotic cells, multicellular organisms; cell membrane and cell wall, cell organelles; chloroplast, mitochondria, vacuoles, ER, golgi apparatus; nucleus, chromosomes – basic structure, number. Tissues, organs, organ systems, organism. Structure and functions of animal and plant tissues (four types in animals; merismatic and permanent tissues in plants).
Health and diseases : 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.
Transport of materials in the living systems : Diffusion / exchange of substances between cells and their environment and between the cells themselves in the living system; role in nutrition, water and food transport, excretion, gaseous exchange.
Theme : Moving things, people and ideas
Unit III: MOTION, FORCE AND WORK
(60) Periods
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, equations of motion by graphical method; elementary idea of uniform circular motion.
Force and Newton’s laws : 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.
Gravitation: Gravitation; universal law of gravitation, force of gravitation of the earth (gravity), acceleration due to gravity; mass and weight; free fall.
Work,Energy and Power : Work done by a force, energy, power; kinetic and potential energy; law of conservation of energy.
Floatation: Thrust and pressure. Archimedes’ principle, buoyancy, elementary idea of relative density.
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.
