How To Understand Forensics

Transcription

1 FORENSIC SCIENCE ELECTIVE CORE The Forensic Science Elective Core focuses on the analysis of evidence collection, the decomposition process, crime scenes, skeletal remains, toxicology, and document validity. Case studies and crime scenarios help students understand the implications and complicated issues that are emerging as the science of forensics continues to develop. The Forensic Science Elective Core is not intended to serve as the entire curriculum of any course. Teachers are encouraged to expand the curriculum beyond the minimum content of this core, accommodating specific community interests and utilizing unique local resources. Courses developed from this core should encourage critical thinking, use of the scientific method, integration of technology, and application of knowledge and skills learned to the solving of practical questions and problems. The scientific process and application skills located on page 10 of this document should be incorporated into as many course standards as possible. It is also essential that students place theories and discoveries of significant persons into a historical perspective. Students should use clear and accurate language, keep accurate records, make reports, present oral and written projects, and participate in discussions regarding the results and conclusions of scientific investigations. Safe field and laboratory investigations should be used in instruction to the maximum extent possible to illustrate scientific concepts and principles and to support inquiry-based instruction. The recommended prerequisite science course for the Forensic Science Elective Core is the Biology Core. Students will: 1. Describe responsibilities of various personnel involved in crime scene investigations. Examples: police, detectives, laboratory specialists, medical examiners 1.1. Explaining how to search, sketch, and record data from a crime scene 2. Explain ways to collect and preserve evidence from a crime scene Distinguishing between physical evidence and witness evidence 2.2. Comparing the three main pattern types that combine to form an individual s unique fingerprint 2.3. Explaining different methods of latent fingerprint development 2.4. Identifying origins of impressions, including footwear and tire treads 2.5. Describing ways to identify hair, fiber, and blood evidence 3. Distinguish between class and individual characteristics of firearms. Examples: toolmark, caliber, scatter pattern

2 4. Describe presumptive and confirmatory tests. Examples: blood type comparison, DNA testing 5. Describe the importance of genetic information to forensics Using the process of gel electrophoresis to identify patterns in DNA 6. Describe the decomposition process Using rigor mortis to determine corpse position 6.2. Identifying decomposition by-products to determine cause of death 6.3. Using entomological life cycles to determine time of death 7. Identify the importance of skeletal remains in forensics Comparing bones and skulls based on age, sex, and race 7.2. Using forensic dentistry to establish identity 8. Describe general categories of drugs and poisons and their effects on humans Explaining ways poisons are detected at autopsy 9. Use laws of physics to explain forensic evidence Analyzing blood splatter patterns in relation to speed, height, and direction 9.2. Tracking trajectories of collected evidence 10. Describe techniques used to determine the validity of documents. Examples: fiber and handwriting analyses, ink chromatography
