The teacher prepares five GCSE-style multiple-choice questions on electrolysis, each with distractors built from common misconceptions, such as the idea that electrons flow through the electrolyte. Students vote individually on Mentimeter with the results hidden. The teacher then reveals the spread and follows a set rule: above 70% correct, a quick explanation and move on; between 30% and 70%, students turn to a neighbour who chose differently and argue for two minutes before a re-vote; below 30%, a short reteach. The lesson ends with the teacher explaining why each distractor looked convincing.
