Fingerprinting – Science Masterclass

Apologies for the delay in getting the photos from last week’s masterclass up on the blog!

Last week in the science masterclass, we learned all about fingerprints. Fingerprints are unique and have been used to identify people for over 100 years. We learned about the 3 basic pattern types: loops, whorls and arches and then tried recording our partner’s fingerprints using the inkpads. It was a lot more difficult to get a clear set of fingerprints that it first appeared!

In the second part of the masterclass, we practised dusting for fingerprints after leaving impressions on a plastic cup. We had to be very careful with the carbon powder and fine-haired brushes so we didn’t deposit too much powder on the fingerprint. Once we had dusted and removed the excess powder, we used a sticky strip to remove the print and stored it on black card for easier identification.

What a lot of fun with fingerprints!
