This lesson is designed for the NEW AQA Trilogy Chemistry GCSE, particularly the ‘Chemical changes and electrolysis’ SoW.
 
Students are firstly introduced to the idea of a displacement reaction using an example of aluminium and iron oxide, pupils will then be given a list of chemical reactions and for each one students will need to decide whether a displacement reaction will occur.
 
Students will now conduct an investigation whereby they will place a metal - copper, magnesium, iron and zinc - into copper sulphate solution and observe what happens. Using the results from this investigation, students should decide on the order of reactivity of these metals. Students are now given another list of reactions, for each one students need to now decide if a displacement reaction will take place and if so write out the word equation for each. Students can mark their work using the answers provided.
 
The next part of the lesson focuses on oxidation and reduction, firstly students are provided with a definition of these two processes. They are then shown how to write an ionic half equation to demonstrate what is happening what is happening during a displacement reaction, which metal has been oxidised and which has been reduced. Pupils need to complete the ionic half equations for a list of reactions, pupils can assess their work against the answers provided on the PowerPoint presentation.
 
The last task is a progress check, students need to work their way through a set of questions to assess what they have learnt this lesson. The answers to which are included on the PowerPoint slides forstudents to self-assess or peer-assess their work.
 
The plenary task is for pupils to write a twitter message about what they learnt this lesson, no more than 140 characters and #keywords!!
