A car has been found abandoned with keys in the ignition on the side of the road. What happened to the driver? Who else might be involved?
Students will analyze document, blood typing, fiber, and fingerprint evidence to determine what may have happened to the driver of the car. There are pre-activity questions, evidence analysis worksheets and questions, and conclusion questions.
This is a great forensic science activity. It can be used in a general science class as well, students will need to understand how blood typing works to understand the outcome of the tests.
Teacher Prep: There are lab components to this activity (can't do a lab? Check out this version
of the same activity without lab). Or you can buy both versions in this bundle
-For the document analysis the teacher will need to shred a provided document, a paper cutter or scissors will work, but if available a straight cut shredder is the fastest route. (I enlist student volunteers for this part!) Tape is needed for reconstruction.
-For blood typing you can use a prepared blood typing kit which are commercially available. Instructions are also provided for doing blood typing with milk and vinegar.
-For fiber testing you will need three different fiber types. The lab is written using blue cotton denim, rayon, and polyester. If you need other fabrics or colors e-mail me with your order number and I will modify the document. The fiber tests are microscopic examination (microscope needed) and flame tests (flame source-candle is fine and forceps needed)
