Year 5 CSI - Who killed Humpty?

Lesson: Science

Class: Year 5 Year: 2018 - 2019

Year 5 have been using their CSI skills to wow in our new science topic.  They returned from lunch to find a chalk outline of poor old Humpty Dumpty who had met an unfortunate end over the course of dinner. Luckily lots of evidence was left behind from the killer.  Year 5 used their crime scene investigation skills to determine who killed Humpty.  Workstation one compared our own footprints to that of a print left behind by the killer.  Focussing on size and shape to confirm the killer was a tall male and provide the clue of DE. Workstation 2 was a set of chromotagraphy experiments to acheive some chemical analysis on which pen was used to write the note left behind.  This gave us the clue of EAR. Workstation 3 provided us with a torn up note which we had to piece together establishing a motive and giving us the clue of EY. The final fingerprint was a partial fingerprint left behind by the killer. We took our own fingerprints and analysed the loops, whorls and curls to compare the partial print to some previous suspicious characters and give us the clue of SL. 

We figured out who killed Humpty, but can you?
