How to Detect a liar

This power point discusses how children can detect a liar. It talks about different techniques which can work out if someone is lying such as a lie detector and body signs such as blinking. This was used during a whole school detective day. When the children came into school there was a crime scene, after a discussion in assembly the children were separated into groups and then had different challenges to complete. This PPT was discussed after the children worked out a clue using a hidden code. The other groups looked at fingerprints, measuring the floor footprint at the scene and analyzing a hair sample found at the scene.
