The Truth is out there!

Have a set of cards linked into the topic being studied spread out on the table in front of you. Split class into groups and then ask a series of questions.

When they get an answer right they come out and pick a card then return to their group.

When all the cards are distributed they have to then decide what cards are useful to them for investigating the key question of the lesson and what are 'red herrings'.

At the end of the lesson a good plenary is to get them to explain how and why they came to the decision they did in terms of choosing and refusing the cards.
