Course Content
Reduction & Oxidation
Explore the concepts of oxidation and reduction through various perspectives—electron transfer, oxygen/hydrogen gain or loss, and changes in oxidation states. Learn to identify redox reactions and conduct common tests for oxidising and reducing agents.
0/3
Electrochemistry
Investigate how electrical energy interacts with chemical changes through electrolysis and the workings of electrochemical cells. Learn about ionic movement, electroplating, and hydrogen fuel cells.
0/3
Periodic Table
Discover trends in reactivity and structure in the Periodic Table. Focus on Group 1, Group 17, Group 18, and transition metals, and study their chemical behaviour and real-world uses.
0/3
Metals
This topic introduces the essential physical and chemical characteristics of metals, their position in the reactivity series, methods of extraction, and applications in daily life. Students will also explore issues such as corrosion and its prevention, linking theory with real-world applications.
0/4
Chemical Energetics
Understand how energy is transferred during chemical reactions. Learn to distinguish between exothermic and endothermic changes using energy profile diagrams.
0/2
Rate of Reactions
Explore the factors that affect reaction rates, including temperature, concentration, surface area, and catalysts. Use data to analyse trends and draw conclusions.
0/3
Organic Chemistry
Delve into hydrocarbons, alcohols, esters, and polymers. Understand functional groups, reactions, and environmental impacts.
0/4
Maintaining Air Quality
Understand air composition and common pollutants. Study the carbon cycle, acid rain, ozone depletion, and sustainable solutions to mitigate pollution.
0/2
Secondary 4 Chemistry
About Lesson

Understand the conduction of electricity through ionic compounds in molten or aqueous states, and how this leads to chemical decomposition.
