Pupils in J5 at Highclare Woodfield were thrown into a real CSI scenario during their science lesson in order to help them solve the problem of the missing pencil case. A real ‘who dunnit’ problem saw them using the forensic process of chromatography to identify the pen that was used to write a ransom note! The evidence J5 collected proved invaluable in helping the pencil case be returned to its rightful owner.
