Students are given character cards, some pro and some anti dropping the bomb ranging from Einstein and Churchill to Hirihito and Stalin. In groups each side then works through 36 cards which are teeming with precisely selected historical detail, some of which support the dropping of the A-bomb and some of which argue against it. This activity prepares students exceptionally well for a debate about one of the most keenly argued historical topics - the dropping of the atomic bombs - and can also be used to help students structure an extended written response to this question. The cards are colour-coded for students who require additional differentiation. This is one of my best lessons year on year and I hope it gets your students talking, evaluating, and arguing - especially in this nuclear world which we live in today.
