Learning outcomes
-
Understanding chemical reactions: Recognise a chemical reaction as a process involving the transformation of reactants into products, indicated by observable changes such as colour, state, temperature, or gas evolution.
-
Writing and balancing chemical equations: Learn to represent chemical reactions accurately using symbols and formulas.
-
Classify types of chemical reactions: Identify and differentiate between various types of chemical reactions, such as combination, decomposition, displacement, and double displacement reactions.
-
Apply oxidation and reduction concepts: Understand oxidation and reduction processes in reactions and recognise their importance in real-life phenomena like corrosion.
-
Relate chemical reactions to daily life: Relate concepts like corrosion and rancidity to real-life scenarios, understanding their causes and preventive measures and their impact on materials and food.
