Forensic science
can be defined as the application of science to the law. In criminal cases
forensic scientists are often involved in the search for and examination of
physical traces which might be useful for establishing or excluding an
association between someone suspected of committing a crime and the scene of the
crime or victim. Due to a crime scene’s diverse characteristics, forensic
science can be considered a combination of both a social science and a physical
science. Some of the sciences that are useful during a crime scene investigation
may include physics, chemistry, biology, psychology, and criminal justice.
Studying forensic science
can be fun and interesting. It is a way to attain higher level thinking skills
as well as acquire scientific knowledge. However, studying forensic science is a
lengthy and difficult process and due to the involvement of many subject areas,
it takes collaborative efforts to extract the needed crime scene information.
Learning
Forensic Science in Secondary Schools
The lack of background knowledge, insufficient funding, and highly technical
equipment have kept secondary schools away from introducing forensic science as
part of mainstream science curriculum. In order for high school students to
acquire a knowledge base centered on forensic science, it is necessary that
classes teach advance levels of biology, chemistry, and physics. Also, it would
be ideal to include series of law enforcement related classes on topics such as
criminal investigations, latent fingerprint development, firearms
identification, and questioned documents.
Recently, the availability of forensic activity kits and simple methods of
analyzing mock evidence have helped to build forensic science projects in
secondary schools.
Bergen County Technical Schools is now in the fifth year of the Tech-Prep Grant:
Engineering, Science, and Technology Program which has focused on engineering
for the life sciences. The course work is based on Biotechnology with additional
exposure to Biology, Physics, and Chemistry.
Forensic science allows for extensive research skills including highly
sophisticated experiments, analytical and logical thinking, and data collection.
Therefore, this project is for students who might consider pursuing their career
not only in forensic science, but in biotechnology engineering as well.
By the end of this project,
students should be able to answer the following questions:
 | What kinds of techniques are available for forensic scientists and/or
investigators? |
 | How does biology, biotechnology, chemistry, and physics
play role in crime scene investigation? |
 | What types of information are important to determine a
perpetrator? |
 | What are antibodies, antigens, and DNA electrophoresis? |
 | What are the drawbacks of using scientific method in
forensic science? Are facts always reliable anytime and anywhere? |
Students are responsible to perform series of activities to
determine the perpetrator among suspects. Each activity is designed with
laboratory experiments, so they can get a feel of being a real forensic
scientist. Prior to each activity, students will learn course related theories
and lessons. Since integrating the Project Lead the Way (PLTW) programs into the
high school curricula is an important task, instructor should closely follow
objectives of each activity under guideline of New Jersey Core Content
Curriculum Standards. Once students master the background theories and
concepts, then they may carry out each activity to solve the given problem.
Students gaining analytical thinking and keen observation skills through this
project are others goals of the educators. Most of the background information
is provided in this project, but it is encouraged that students seek other
information, which may be lacking from the Background/Theory page, from reliable
sources.
Project Length
The project length depends on students’
prior knowledge regarding biology and biotechnology, chemistry, physics etc. The
instructor should deliver concepts of DNA and how biotechnology is implemented
in real world application. Therefore, total project length is dependent upon the
number of activities the teacher chooses to perform with the class. For specific
activity length, please refer to individual group activity.
