Forensic Biology

A scientist is very similar to a detective. Both use investigative thinking to solve problems and require skill in careful observing, forming hypotheses and drawing conclusions from well organized data. In this event you will assume the role of a forensic investigator to gather and analyze samples of biological material from a crime scene.

Participants Teams of up to six.
Procedure The investigation will involve locating, identifying and/or otherwise analyzing various types of biological evidence including hair, blood, fingerprints, DNA fingerprints and conifer needles. The objective of the investigation is not to discover "who done it" but, rather, to collect, analyze and report on the evidence in support of a hypothesis.
Forensic Kit On the day of the Olympics, a "Laboratory", equipped with a compound microscope and a dissecting microscope will be provided for each team. Individual teams are expected to assemble and bring their own Forensic Kits containing the remaining reagents, equipment and reference slides etc. as described in the Instruction Manual. Your kit may include protocols as well as other reference material. Specialized reagents will be provided at the workshop.

Judging Teams of six students will have access to their crime scene and Laboratory for one hour. Reports are due after an additional half hour. Points will be awarded on the basis of a team's ability to (i) locate and accurately analyze the types of evidence addressed in this exercise and (ii) draw logical conclusions regarding the crime events or suspects.
