Carbon compounds: Covalent bonding in carbon compounds. Versatile nature of carbon. Homologous series. Nomenclature of carbon compounds containing functional groups (halogens, alcohol, ketones, aldehydes, alkanes, and alkynes), the difference between saturated hydrocarbons and unsaturated hydrocarbons. Chemical properties of carbon compounds (combustion, oxidation, addition, and substitution reaction). Ethanol and Ethanoic acid (only properties and uses), soaps, and detergents.

Unit II: World of Living

Life processes: ‘Living Being’. Basic concept of nutrition, respiration, transport, and excretion in plants and animals.

Control and coordination in animals and plants: Tropic movements in plants; Introduction of plant hormones; Control and coordination in animals: Nervous system; Voluntary, involuntary, and reflex action; Chemical co-ordination: animal hormones.

Refraction of light by the spherical lens; Image formed by spherical lenses; Lens formula(Derivation not required); Magnification. Power of a lens.

The Human Eye and the Colourful World: Functioning of a lens in a human eye, defects of vision and their corrections, and applications of spherical mirrors and lenses.

Refraction of light through a prism, dispersion of light, scattering of light, and applications in daily life (excluding the color of the sun at sunrise and sunset).

Unit IV: Effects of Current

Electricity: Electric current, potential difference, and electric current. Ohm’s law; Resistance, Resistivity, Factors on which the resistance of a conductor depends. The series combination of resistors, parallel combination of resistors, and its applications in daily life. Heating effect of electric current and its applications in daily life. Electric power, Interrelation between P, V, I, and R.

Magnetic effects of current: Magnetic field, field lines, field due to a current carrying conductor, field due to current carrying coil or solenoid; Force on a current carrying conductor, Fleming’s Left Hand Rule, Direct current. Alternating current: frequency of AC. Advantage of AC over DC. Domestic electric circuits.

Unit V: Natural Resources

Our environment: Eco-system, Environmental problems, Ozone depletion, waste production, and their solutions. Biodegradable and non-biodegradable substances.

Note: 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.
