Peter Thomas Narrator as Narrator voice. Julie Busken Self as Self archive footage. Storyline Edit. A college co-ed was abducted from a parking lot near her apartment in the early morning of Christmas day.
Her body was found later in the day and she had been both assaulted and shot at point blank range. Eight years later, a cell phone and a pair of running shoes has breathed life back into this very cold case. Add content advisory. User reviews Be the first to review.
Details Edit. Sand from a stream might consist of rounded grains, and its compositiion will reflect the soils and bedrock from upstream locations in the drainage basin. Manufactured sand will be very different. It is made by crushing rocks and the particles will be very angular. Trace evidence can be a challenging unit to teach high school students with Early Onset Senioritis. The microscope work can be tedious and students' attention to detail wanes easily. However, I know that my students come to class thinking that dirt is dirt and sand is sand; they fully believe that there is little difference between samples or that telling the differences involves intricate analysis that is beyond their comprehension.
The Murder on the Beach lab is relatively easy to prepare, uses tests and data beyond microscope work, and includes a mystery for students to solve. In part one of the lab, the students review known samples of sand - those that were taken from the suspects. I usually give the students about 50 minutes for this part. Part two requires the students to analyze a sample of sand found on the victim and to identify which of the suspects committed the crime. Visit their website for more ideas about teaching forensic science.
If you live near a beach, an initial sand sample is easy to obtain. The rest can come from just about any pet or aquarium store - several varieties are available for reptiles and fish. Most of these samples are going to be a relatively neutral pH, so I treat the samples ahead of time to give the students some measurable differences. I generally start with three or four very different samples, then make combinations to create more samples, giving me a total of seven different samples for the lab.
For the second part of the lab, I prepare enough samples so that every student gets his or her own victim sample to test. This way, students can work together to share observations, but everyone has to come up with his or her own final answer.
