A fully-resourced lesson which includes a lesson presentation (24 slides) and a worksheet which is differentiated so that students can judge their understanding of the topic of writing half equations for electrolysis and access the work accordingly. The lesson uses worked examples and helpful hints to show the students how to write half equations at both the cathode and anode. Time is taken to remind students about the rules at the electrodes when the electrolyte is in solution so that they can work out the products before writing the equations.
This lesson has been designed for GCSE students (14 - 16 years old in the UK) but could be used with older students.
