Lesson Topic: Identify oxidation and reduction in redox reactions
Learning Objective/s:
  • Describe oxidation and reduction concepts and the roles of oxidising and reducing agents.
  • Apply IGCSE oxidation‑number rules to assign numbers to atoms in chemical equations.
  • Identify which species are oxidised and which are reduced in a given redox reaction.
  • Determine the oxidising and reducing agents once the equation is balanced.
  • Solve practice problems using the step‑by‑step identification method.
Materials Needed:
  • Projector or interactive whiteboard
  • Printed worksheets with redox equations
  • Oxidation‑number reference cards
  • Calculator
  • Whiteboard and markers
  • Optional: molecular model kits
 Introduction:
Begin with a quick demonstration of a metal reacting with acid to produce hydrogen gas, prompting students to consider electron transfer. Review the definitions of oxidation and reduction and the IGCSE oxidation‑number rules they have previously learned. Explain that by the end of the lesson they will be able to reliably identify which species are oxidised, reduced, and the corresponding agents in any redox equation.
Lesson Structure:
  1. Do‑now (5'): Students assign oxidation numbers to simple compounds on a short worksheet (check).
  2. Mini‑lecture (10'): Review oxidation‑number rules and introduce the six‑step identification method (check).
  3. Guided practice (15'): Work through Worked Example 1 (Zn + CuSO₄) together, discussing each step (check).
  4. Paired activity (15'): Students tackle Worked Example 2 (Fe + Cl₂) and a practice question on Mg + HCl, recording oxidised/reduced species and agents (check).
  5. Whole‑class discussion (5'): Share answers, clarify misconceptions, and reinforce the agent concept (check).
  6. Exit ticket (5'): Each student writes one redox equation and labels the oxidised, reduced, oxidising and reducing agents (check).
Conclusion:
Summarise the six‑step method and highlight how the oxidation‑number rules guide the identification process. Collect exit tickets to gauge understanding, and assign the remaining practice questions as homework for reinforcement.
