KS2 Who, what, where, when, why, how. Pupils should write: six sentences, each beginning with one of these; six more sentences, each with one of them in the middle.
KS3 If pupils could travel back in time, which historical period (including the 20th century) would they choose to visit, and why? They should also consider the disadvantages of living in their chosen time.
KS4 Give pupils a short briefing on Doctor Who, and ask them to consider: why he is called a doctor; why it is possible for the actor playing the part to change every few years; their ideas for the next incarnation.
