This is a fun deductive reasoning and skills based lab determining the culprit at a crime scene using lip printing skills. Students will evaluate and sketch different lip prints from 10 different suspects and compare it to a crime scene lip print to determine which one most closely matches to solve the crime. Students are provided brief profiles on each suspect and are required to determine a possible motive and write a formal letter to the school principal stating who they believe committed the crime, citing their evidence and possible motive.
I use this lab as an extension during my unit on fingerprinting in my high school Forensic Science classroom but it is appropriate for middle school as well. There is one 3 page document with background information on the science of lip print analysis and one four page student handout for the lab, as well as one page for teacher hints and information. Enjoy!
