Learning Intention: We are learning what a fingerprint is
– I understand that everyone has a unique fingerprint
– I can identify the key features of my own fingerprint
– I know how and why the police use fingerprints to help them solve crimes

As part of our STEM IDL context, Kidnapped, P5B have been receiving missions from Police Chief Anderson to help Police HQ to find Jack and Sarah Green. This week, we discovered that a fingerprint was found on the strap of a watch belonging to Jack. Chief Anderson sent our investigation teams a fingerprinting kit so that we could find out more about our own fingerprints. 

We learned there are 3 main characteristics to look for; loop, whorl and arch. We put our fingerprints onto a balloon first and inflated it so that we could see our print pattern more clearly. We used magnifying glasses to get an even closer look.

We then took prints of all ten of our fingers and analysed them to find the specific characteristics of each one. It was interesting to compare all ten fingers and see which was the most common characteristic. We recorded out findings and added this to our growing case files.

We also discussed how difficult it must have been for the police to match fingerprints in the days before technology. We used our own and the school devices to find out when the first crime was solved using fingerprint evidence- all the way back in 1892!
