1. Chemical reactions and equations — writing and balancing; combination, decomposition, displacement, double displacement; oxidation and reduction; corrosion and rancidity.
2. Acids, bases and salts — properties; pH in everyday life; chemicals from common salt (NaOH, bleaching powder, baking soda, washing soda, Plaster of Paris).
3. Metals and non-metals — physical and chemical properties; reactivity series; ionic compounds; extraction and refining; corrosion.
4. Carbon and its compounds — covalent bonding; homologous series; nomenclature; ethanol and ethanoic acid; soaps and detergents.
5. Life processes — nutrition, respiration, transportation, excretion.
6. Control and coordination — nervous system, plant coordination, hormones in animals.
7. How do organisms reproduce? — asexual modes; sexual reproduction in plants and humans; reproductive health.
8. Heredity — variation, Mendel’s contribution, sex determination.
9. Light — reflection and refraction — mirrors and lenses; formulas and magnification.
10. Human eye and colourful world — accommodation; defects of vision; prism, atmospheric refraction, scattering.
11. Electricity — Ohm’s law, series/parallel, heating effect, electric power.
12. Magnetic effects of electric current — field lines, right-hand thumb rule, force on a conductor, domestic circuits.
13. Our environment — ecosystem, food chains, ozone, waste.

The official PDF lists laboratory practicals (for example iron nail in copper sulphate, pH paper, water of crystallisation, esterification, salivary amylase).
