Category: bio-tech crime scene investigation
Brief Description: Students will gather "data" from 10
of their classmates and submit a list of those contributing classmates names to
the teacher. The teacher will then select 1 of the people to be the guilty party
and develop the crime scene for student assessment and analysis. Students
will make deliberate observations about the crime scene. They
will sketch the scene, preserve the scene, gather evidence and scout for 3 forms
of biometric evidence. Finally, they will determine
the "guilty" party based on their database of biometric data.
Duration: 3 X 80 minute
classes
Goals: Give students a better understanding of
biotechnology used to gather forensic evidence and the protocol necessary in the
acquisition of that evidence.
Objectives: The students will use established protocol
to secure and analyze a crime scene.
The students will be able to describe and analyze 3 types of biometrics -including fingerprints, iris scans and dental forensic patterns
The students will be able
to identify the "guilty" party based on gathered and provided
data and their research about identifying the unique characteristics involved in
biometrics.

Pictures of fingerprint characteristics, iris characteristics
and dental characteristics.
Digital Camera, computer/imaging software and printer,

index cards, carbon paper, magnifying glass, rubber gloves
and evidence bags

Student Resources: Same as teacher materials
Procedure: Students will be given the task of:
- gathering "data" from 5 of their classmates. Then they will submit a list of those contributing classmates names to the teacher.
-The teacher will then select 1 of the people to be the guilty party and submit biometric samples to the investigators via the crime scene.
-the students will define and make observations about a classroom crime scene.
-They will sketch the scene, photograph evidence sites, preserve the scene, gather evidence and scout for 3 forms of biometric evidence.
When they complete this task, each group will explain why they chose
the guilty party they designated in that particular
manner.
Assessment: The student will sketch the key elements
of the crime scene, photograph evidence sites, secure the evidence using
correct, non-contaminating techniques and finally correctly identify the
"guilty" party or understand why their assessment was incorrect.
