- Introduce the idea that scientists collect data or evidence and that they try to think creatively to explain this evidence. Theories result from scientists relating their ideas to the evidence and refining their ideas.
- Present pupils with a game or puzzle to play,
eg a murder mystery game, where each group is given some evidence about an event,
eg a fictitious murder, and is asked to establish what happened on the basis of the evidence.
- Provide further evidence, which could be given part-way through, to encourage pupils to modify their original suggestion on the basis of the new evidence. Ask pupils to reflect on their ideas, to explain why they arrived at their first conclusion, and what caused them to change their ideas.

|
- evaluate the ideas of others and collectively create a solution to the game/puzzle which is consistent with the evidence
- explain how their solution is consistent with the evidence and, if necessary, why they had to change their ideas
