Forensics

Although I have been interested in forensics for many years, the cost of textbooks, for student use for a part of a course, was too prohibitive. In May 1993, there were 5 excellent short articles printed in Chemistry in Britain (the monthly journal from the Royal Society of Chemistry). Using the 5 articles for class text material, I started teaching hands-on forensics in the classroom in the Fall of 1993, writing the hands-on activities/experiments myself. Currently, the forensics portion of my course contains the following activities and information along with articles from a number of sources which are provided to my students on a CD-ROM.

If you are enrolled in CHM 128IN, do not download experiments from this page. Go to the CHM 128 page under Pima Chem Courses.

DNA

We use the BioRad Forensic DNA Fingerprinting Kit for class. This is an excellent introduction to DNA analysis. You will need micropipettes, a constant temperature bath, a microcentrifuge, and electrophoresis apparatus for this laboratory experiment. The kit description is on the BioRad Life Science Education web site under Classroom Kits. You can download the manual from this site.

The Forensic DNA Fingerprinting Kit Instruction Manual is available on the BioRad Life Science Education web site under the Kit Instruction Manuals link. You can also access it directly here: Bio-Rad Forensic DNA Manual The student manual starts on page 20 with the Forensic DNA Fingerprinting Kit Quick Guide.
