ICSE Class 6 Chemistry Syllabus

The ICSE takes a genuine attempt to develop the skills and knowledge of the students in an appropriate manner. The board prepares a proper syllabus and other valuable learning materials to impart detailed knowledge in each subject to the students. The ICSE Class 6 Chemistry Syllabus explains the whole chemistry curriculum that has to be covered in the year. The chapters or topics to be covered in the academic year are mentioned clearly, with sub-topics in the ICSE syllabus.

Theme 1: Introduction to Chemistry Elements

1. Chemistry – meaning and importance.
2. Development of Chemistry – A historical perspective.
3. Notable chemists/ scientists and their contributions to Chemistry (at least 3 scientists).
4. Food and Chemistry.
5. Cosmetics and Chemistry.
6. Clothing and Chemistry.
7. Chemicals as Medicines.
8. Chemicals in Industries.

Theme 2: Elements, Compounds and Mixtures

1) 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).

2) 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).

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

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

5) Separation techniques of mixtures into their components:

• Sieving
• Sedimentation
• Decantation
• Filtration
• Evaporation
• Magnetic Separation
• Sublimation

Theme 3: Matter

1) 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).

Theme 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.

Theme 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 atmosphere as layer of air around the earth.
