Theme:
Materials
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. Heterogeneous and homogenous mixtures, colloids and suspensions. Physical and
chemical changes (excluding separating the components of a mixture).
Particle nature and
their basic units: Atoms and molecules, Law of Chemical Combination, Chemical formula
of common compounds, Atomic and molecular masses.
Structure
of atoms: Electrons, protons
and neutrons, Valency, Atomic Number and Mass Number, Isotopes and Isobars.
Theme: The World of the
Living
Unit II: Organization in the
Living World
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 and cell inclusions; 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
(only four types of tissues
in animals; Meristematic and Permanent tissues in plants).
Theme: Moving Things, People and Ideas 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,
elementary idea of uniform
circular motion.
Force and Newton’s laws : Force and Motion, Newton’s Laws of Motion,
Action and Reaction forces, Inertia of a body, Inertia and mass, Momentum, Force and Acceleration.
Gravitation:
Gravitation; Universal Law of
Gravitation, Force of Gravitation of the earth (gravity), Acceleration due to Gravity;
Mass and Weight; Free fall.
Floatation: Thrust and Pressure.
Archimedes’ Principle; Buoyancy.
Work,
Energy and Power: Work done
by a Force, Energy, power; Kinetic and Potential energy; Law of conservation of energy (excluding commercial unit 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.
Theme: Food
Unit IV: Food Production
Plant and animal breeding and selection for quality improvement and management; Use of fertilizers and manures; Protection from pests and diseases; Organic
farming.
Note for the Teachers:
1. The chapter Natural Resources (NCERT
Chapter 14) will not be assessed in the year-end examination. However, learners may be assigned to read this
chapter and encouraged to prepare a
brief write up on any concept of this chapter in their Portfolio. This may be
for Internal Assessment and credit
may be given for Periodic Assessment/Portfolio.
2. The NCERT text books present
information in boxes across the book. These
help students to get
conceptual clarity. However, the information in these boxes would not be assessed
in the year-end examination.
PRACTICALS
Practicals
should be conducted alongside the concepts taught in theory classes
