Chemistry Class 6 ICSE CISCE Topics and Syllabus

Academic year:


1 Introduction to Chemistry
  • Chemistry – meaning and importance.
  • Development of Chemistry- A historical perspective.
  • Notable chemists/scientists and their contributions to Chemistry (at least 3 scientists).
  • Food and Chemistry.
  • Cosmetics and Chemistry.
  • Clothing and Chemistry.
  • Chemicals as Medicines.
  • Chemicals in Industries.
2 Elements, Compounds and Mixtures
2.1 Elements, Compounds
  • Element (a substance made up of identical atoms).
  • Use of symbols as short hand notations of writing names of elements.
  • Origin of symbols of elements.
  • Names and symbols of first 20 elements.
  • Molecules of elements contain atoms of the same element (O2, N2, H2).
  • Compound (two or more than two elements combine in fixed definite proportions to form a compound. Original properties of the constituent elements are lost and a substance with new properties is formed).
  • Molecules of compounds contain atoms of different elements. (H2O, CO2, NO2, CaO, ZnCl2).
2.2 Mixture

The mixture (components of more than one substance combine in any proportion, original properties of the components are retained).

Difference between mixtures and compounds (on the basis of the proportion of the combination of components and their properties).

Separation techniques of mixtures into their components:
Magnetic Separation.

3 Matter
3.1 Matter

States of Matter

Classification of matter into solid, liquid and gas on the basis of properties (shape, volume). Factors responsible for the existence of matter in different states.

Arrangement of atoms/ molecules in solids, liquids and gases: - intermolecular space, cohesive forces).

There is space between the particles of matter.

Effect of heat on matter (expansion, change of state and chemical change)

3.2 Common Laboratory Apparatus and Equipments
  • Common Laboratory Apparatus and Equipments
4 Water
  • Importance of water in everyday life (household
    purpose, industry, watering plants, etc.)
  • Water resources (well, river, hand pump, lakes, pond, etc.).
  • Capacity to dissolve many salts in it.
  • Definition of Solute, Solvent and Solution.
  • Importance of water for sustenance of life on earth.
  • Reasons for water pollution; its prevention; conservation of water.
5 Air and Atmosphere
  • Air is present everywhere around us.
  • Air - a mixture of gases namely, nitrogen, oxygen, carbon dioxide, water vapour; dust and smoke as pollutants.
  • Percentage composition of air.
  • Uses of the components present (importance of nitrogen to plants to be mentioned).
  • Definition of the atmosphere as the layer of air around the earth.
