Fingerprint Activity

I found this activity online somewhere.  I think it was actually an activity for an English class, but I figured it tied into Forensics nicely.  After the first round of fingerprinting, the students tried to recreate the basic pattern of their fingerprint, but instead of ridges they used words.  They could write about anything they wanted and many personalized their fingerprints.

  This took considerably longer than I had figured.  I figured a half a period to one day and I think it took two to three days for most of them to finish, and the rest had to finish at home (I normally don't give homework in Forensics).

What do you think?
