Forensics and English

Posted by quirksalight on February 9, 2009

Last week was the second to last week I’ll be in the classroom. It’s also a great group of students to work with, as this was the “English Camp” and the students are self-selecting… I don’t have to push them, they all WANT to be in school. 🙂 Just awesome…

So I tried to keep things interesting… hence, the last two days, we learned about some simple forensics. What it was, fingerprints and fingerprinting, invisible ink, and ink analysis by paper chromatography.
