Our CSI camps were still going strong yesterday as our gumshoes worked through a number of new CSI activities. And the name of the game for Day 3: the human body. First, campers were treated to a presentation by Medical Examiner Dr. Sheila Spotswood, who gave our girls a glimpse into a day in the life of a medical examiner.
After being acquainted with this new profession, campers learned how a person’s body, and even the way they move, can reveal a ton of information about them in the Forensic Anthropology and Gait Recognition activities.
Then, after grabbing a quick bit to eat, campers moved into an in-depth DNA exercise: the DNA Electrophoresis Lab. DNA electrophoresis is a technique used by forensic scientists where they compare DNA samples found at a crime scene with the DNA of suspects in a case. Scientists are able to use restriction enzymes (protein “scissors”) that cut a piece of DNA at specific points in the sequence. Because everyone’s DNA sequence is different (unless you have an identical twin), the pieces of DNA that are cut will be different lengths.
Lastly, the girls concluded their day by getting insight into the day in the life of an NCIS agent from Special Agent Don Goates.
After their third day of camp, these students have gained a number of CSI skills. Yet there’s still much more to come, so stay tuned to find out what Day 4 had in store for these investigators-in-training!
