Our first week of Forensic Science camp has proved to be a
very interesting, intriguing and fun one! We have truly gotten into the minds
of criminal investigators, exploring techniques from fingerprint identification
to tool impressions!
On Monday, we learned about some forensics basics, including
crime scene vocabulary, types of evidence and crime scene protocol. We did an activity
to practice our observation skills, in
which campers acted out a variety of crimes and we had to recall details of the
criminal and the crime afterwards. We also discovered our
dinosaur poster from the Education Room was stolen! We had to investigate the crime scene by
carefully sketching and measuring the evidence.

On Tuesday we did a Handwriting Mystery to understand how
investigators take samples of suspects’ handwriting and compare it to ransom
notes or other handwriting samples from the crime scene. We studied many
methods of handwriting analysis, including line quality, size and proportion
and pen lifts, to match our handwriting samples to the specimen. We
took our own fingerprints and looked at them closely to find patterns and
points of identification.We also took our shoe prints by
spraying WD-40 on the bottoms of our shoes, taking steps on paper and then
using magnetic powder to see the unique features.

On Thursday, we did a fiber analysis in which we looked at
different fibers under a stereoscope. Investigators often use this method to
match unique fibers on a victim’s clothing to the clothing of a suspect. We
learned that natural fibers have intertwined strands while synthetic fibers
have straighter strands. We also learned how tool marks are used as
evidence. We looked at the impressions of different tools and sketched and took
measurements to determine which impression belonged to the tool from the crime
scene. Tool impressions can be used when a criminal pries open a window or
door, or if there is a dent left from an impact.

On Friday, we had an exciting crime to solve! A piece of
amber was stolen out of our display case, and it was up to the campers to
figure out which of the 4 suspects committed the crime. We used fingerprint,
shoeprint, and handwriting analysis along with deductive reasoning to find our
criminal. The campers did an awesome job and successfully convicted Suspect #4!
(Don't worry parents, it was a mock crime scene.) We also used our deductive reasoning skills to find the criminal of another
crime using clues.
