This lab can be done in groups of 2, 3 or 4. It could also be done alone if need be. All that is needed are the lab papers. Students feels like forensic investigators as they look at the evidence from a crime scene like blood type, fingerprints, lip prints and DNA segments. No prior knowledge of DNA or blood types is needed as all of the needed information is given in the lab. It is a fun lab to give students at the beginning of the Biology year to get them working as a group or at the end when testing is done. This lab/activity could be done by honors 7th and 8th graders besides Biology students in high school.
