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.

basic unit of life; prokaryotic and eukaryotic cells, multicellular
organisms; cell membrane and cell wall, cell organelles; chloroplast,
mitochondria, vacuoles, endoplasmic reticulum, Golgi apparatus; nucleus,
chromosomes - basic structure, number.
Tissues, Organs, Organ System, Organism: Structure and functions of animal and plant tissues (four types in animals; meristematic and permanent tissues in plants).
Unit III: Motion, Force and Work
Motion: Distance and
displacement, velocity; uniform and non-uniform motion along a straight
line; acceleration, distance-time and velocity-time graphs for uniform
motion 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.
Unit V: Food Production
Plant and animal breeding and selection
for quality improvement and management; use of fertilizers, manures;
protection from pests and diseases; organic farming.
Second Term Units
Unit I: Matter - Its Nature and Behaviour
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
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
classes).
Health and Diseases:
Health and its failure. Infectious and Non-infectious diseases, their
causes and manifestation. Diseases caused by microbes (Virus, Bacteria
and protozoans) and their prevention, Principles of treatment
and prevention. Pulse Polio programmes.
Unit III: Motion, Force and Work
Floatation: Thrust and pressure. Archimedes' principle, buoyancy, elementary idea of relative density.
Work, energy and power: Work done by a force, energy, power; kinetic and potential energy; law of conservation of energy.
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).
Unit IV: Our environment
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
ozone layer and the probable damages.
Bio-geo chemical cycles in nature: Water, oxygen, carbon and nitrogen.
First Term Practicals
1. To test (a) the presence of starch in the given food sample, (b) the presence of the adulterant metanil yellow in dal.
2. To prepare:
- a) a true solution of common salt, sugar and alum
- b) a suspension of soil, chalk powder and fine sand in water

- transparency
- filtration criterion
- stability
3. To prepare
- a) a mixture
- b) a compound
using iron filings and sulphur powder and distinguish between these on the basis of:
- i. appearance, i.e., homogeneity and heterogeneity
- ii. behaviour towards a magnet
- iii. behaviour towards carbon disulphide as a solvent
- iv. effect of heat
4. To carry out the following reactions and classify them as physical or chemical changes:

- b. Burning of magnesium in air
- c. Zinc with dilute sulphuric acid
- d. Heating of copper sulphate
- e. Sodium sulphate with barium chloride in the form of their solutions in water
5. To prepare stained temporary mounts
of (a) onion peel and (b) human cheek cells and to record observations
and draw their labeled diagrams.
6. To identify parenchyma and
sclerenchyma tissues in plants, striped muscle fibers and nerve cells in
animals, from prepared slides and to draw their labeled diagrams.
7. To separate the components of a mixture of sand, common salt and ammonium chloride (or camphor) by sublimation.
8. To determine the melting point of ice and the boiling point of water.
9. To establish relationship between
weight of a rectangular wooden block lying on a horizontal table and the
minimum force required to just move it using a spring balance.
10. To determine the mass percentage of water imbibed by raisins.
Second Term Practicals
1. To verify the Laws of reflection of sound.
2. To determine the density of solid (denser than water) by using a spring balance and a measuring cylinder.
3. To establish the relation between the loss in weight of a solid when fully immersed in
- a. tap water
- b. strongly salty water, with the weight of water displaced by it by taking at least two different solids.
4. To observe and compare the pressure
exerted by a solid iron cuboid on fine sand/ wheat flour while resting
on its three different faces and to calculate the pressure exerted in
the three different cases.
5. To determine the velocity of a pulse propagated through a stretched string/slinky.
