AQA 9-1 Topic 4 Chemical changes - Reactivity series and extraction of metals

A lesson looking at the reactivity series, extraction of metals, displacement reactions and the extraction of aluminium using electrolysis
Lesson features include:

• A starter consisting of basic recall questions from previous learning (structure of diamond, alloys, fullerenes, isotopes, properties of ionic compounds, covalent bonding diagrams, relative formula mass and moles)
• Slides introducing the reactivity and displacement recation using an analogy with multiple practice questions
• Slides with prompt questions explaining how th position of a metal in the reactivity series links to the method of extraction
• Slides explaining what oxidation and reduction mean in terms of oxygen with practice questions identifying what is being oxidised/ reduced in reactions
• An explanation of what spectator ions are and guided practice on how to write ionic equations
• A recap of the process of electrolysis and labelling an electrolysis cell
• An animated diagram of the electrolysis of aluminium oxide with prompt questions on the purpose of cryolite and why oxygen does not form at the positive electrode, together with practice exam-style questions on the topic and animated answers.
• A series of exam-style questions and answers to assess student understanding on the topic
