Crime scene Science (blood and crime scene)

A simple CSI lesson - I set up a crime scene with fake blood(made out of jelly and red food colouring and warm water or buy fake blood from the pound store) (i made a hand print, blood drops and a drag mark) a head, some weapons (cricket bat, rolling pin, toy gun) and a sealed packet of drugs (flour taped up in a plastic wallet) - the first lesson had pupils collecting evidence and the second had them analysing the blood splatter from the scene all resources needed are included in the powerpoint
