Forensic Science/ Crime Scene Investigation

Transcription

1 Forensic Science/ Crime Scene Investigation You know what a Crime Scene Investigator looks like on television. Now, get to know the real career. Forensic Science plays a vital role in the criminal justice system providing investigators with scientifically-based information through the analysis of physical evidence. As a student in the Forensic Science/CSI pathway at the Public Service Leadership Academy at Fowler you ll be exposed to the real, everyday life of a crime scene investigator, gaining knowledge and hands-on experience in: Collecting and preserving material evidence found at crime scenes including measuring, recording and analyzing chemical substances (such as tissue samples, physical materials and ballistics evidence) Communicating with experts in fingerprinting, ballistics, handwriting, electronics, documents, chemistry, medicine or metallurgy to interpret evidence Reconstructing crime scenes and testifying as a witness in trials or hearings This pathway will involve a rigorous and relevant four-course Project Lead the Way (PLTW) Biomedical Science sequence. CAREER OPPORTUNITIES: Crime Scene Investigator, Private Investigator, Law Enforcement 73

3 COURSE DESCRIPTION Forensic science is the application of scientific knowledge to questions of civil and criminal law. This course is a lab-based, hands-on course that will explore what forensic scientists do, including modern forensic methods and scientific methods to solve legal problems. This course will focus on collection and analysis of crime scene evidence and lab analysis techniques and the ability to clearly and concisely explain the results of the labs and techniques used, and present details of the analysis in lab reports. The course requires students to apply basic understandings of physics, chemistry, biology and math to explore the range of topics in this diverse field of study. COURSE OBJECTIVES 1. Students will understand the history of the s and its place in popular culture. 2. Students will understand the roles of different types of professionals involved in evaluating a crime scene and the collected evidence. 3. Students will apply the methodology of collecting and interpreting data, avoiding contamination, and preservation of chain of custody. 4. Students will understand how to present evidence in a professional (courtroom) setting.

The topics of the project will be discussed in class and sufficient time will be given to complete the project and present it in class. ADDITIONAL COURSE POLICIES It is your responsibility to ask about any missed work! If you had an excused absence, you will have one day for each day missed to make up any work to receive credit. If you were present on the day an assignment was announced, then you are responsible for that assignment on the day you return. If the absence is known about in advance, you should contact me before the absence to receive the work you will miss. Missed tests have to be made up within 1week of an absence. However missed quizzes only get 3 days to be made-up. You will be responsible to make arrangements with me to make up your tests /quizzes upon returning to school.
