Biological Diversity : 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

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).

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.

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.
Structure of the human ear (auditory aspect only).
Theme : Natural Resources (15 Periods)
Unit 5 : Our Environment

temperatures, movements of air and its role in bringing rains across India.
Air, water and soil pollution ( brief introduction). Holes in
ozone layer and the probable damages.
Bio-geo chemical cycles in nature : water, oxygen, carbon,
