6 RAHWAY PUBLIC SCHOOLS CURRICULUM Content Area: Forensic Science Unit Title: Types of Evidence and Crime Scenes Target Course/Grade Level: Grades 11, 12 Unit Summary: UNIT OVERVIEW How is it possible to identify the person who committed a crime? A single hair or clothing fiber can allow a crime to be reconstructed and lead police to the responsible person. The goal of a crime-scene investigation is to recognize, document, and collect evidence at the scene of a crime. Solving the crime will then depend on piecing together the evidence to form a picture of what happened at the crime scene. Forensic science begins at the crime scene, which can provide useful information that must be carefully, systematically, scientifically, and legally collected. If the crime scene is not treated carefully, it can make vital information not only useless, but even deceptive, pointing an investigation in the wrong direction. The main reason to carefully gather and analyze the crime scene is to learn what happened and to gather evidence that can be used to identify and, ultimately, convict the people responsible.

10 RAHWAY PUBLIC SCHOOLS CURRICULUM Content Area: Forensic Science Unit Title: Forensic Anthropology and Odontology Target Course/Grade Level: Grades 11, 12 Unit Summary: UNIT OVERVIEW The period of time from death to skeletal remains is of interest to the pathologist initially. What is finally left falls in the domain of the forensic anthropologist? Anthropology is the study of humankind including anatomy, variability, evolution, and culture. Forensic anthropology is a type of applied physical anthropology that specializes in the human skeletal system and its changes and variations, for purposes of legal inquiry and ultimately for presentation in the courts of law. A forensic anthropologist can use knowledge of the skeletal system to identify crime victims and sometimes to determine the cause or circumstances of death. The forensic anthropologist can apply information learned from modern forensic cases to the study of skeletons that are hundreds or even thousands of years old.

13 RAHWAY PUBLIC SCHOOLS CURRICULUM Content Area: Forensic Science Unit Title: Hair and Fibers Target Course/Grade Level: Grades 11, 12 Unit Summary: UNIT OVERVIEW Investigators often find hair at the crime scene. Hair is considered class evidence and is useful in backing up other circumstantial evidence, such as by placing someone at the crime scene. The physical characteristics of hair can offer clues to the broad racial background of an individual. It can also adhere to clothes, carpets, and transferred to other locations. Secondary transfer is particularly common with animal hair. Chemical tests can provide a history of the use of drugs and other toxins, indicate the presence of heavy metals, and provide an assessment of nutritional deficiencies. When the follicle of the hair is present, DNA evidence may be obtained. Fibers are everywhere. Because textiles are mass produced, it is difficult to trace a fiber back to a specific source, but fiber evidence is valuable because it creates links among victims, suspects, and places. Investigators identify and compare fibers physically, using microscopy, as well as chemically.

16 RAHWAY PUBLIC SCHOOLS CURRICULUM Content Area: Forensic Science Unit Title: Serology Target Course/Grade Level: Grades 11, 12 Unit Summary: UNIT OVERVIEW Blood left at a crime scene can be analyzed in several ways by a criminal investigator. Blood typing may provide class evidence because more than one person has the same blood type. Because white blood cells contain DNA, it is possible to determine with a high degree of certainty using DNA profiling whether evidence blood left at a crime scene matches the blood of a suspect or victim. Blood spatter evidence can also be used to help recreate a crime scene to validate the information provided by a witness or suspect. By using blood spatter, it is possible to discern the direction from which the blood originated, the angle of impact, and the point of origin of the blood. Further examination of the blood drops might indicate if the blood spatter resulted from a high or low velocity impact, indicating the type of weapon used to cause the injury.

19 RAHWAY PUBLIC SCHOOLS CURRICULUM Content Area: Forensic Science Unit Title: DNA Analysis Target Course/Grade Level: Grades 11, 12 Unit Summary: UNIT OVERVIEW Except for identical twins, no two people have the same DNA. Advances in DNA technology have allowed criminal cases to be solved that previously were thought unsolvable. Since the 1980 s, DNA evidence has been used to investigate crimes, establish paternity, and identify victims of war and large scale disasters. Because each human is unique, DNA evidence from a crime scene or from an unidentified body can be traced back to one and only one person. DNA evidence can be used to link a suspect to a crime or to eliminate a suspect. It can also be used to identify a victim, even when nobody can be found.

22 Content Area: Forensic Science Unit Title: Firearms, Tool Marks, and Ballistics Target Course/Grade Level: Grades 11, 12 Unit Summary: The environment has a way of recording what has happened. People, vehicles, and objects leave evidence of their presence at the crime scene in the form of a mark or an imprint. Impressions fall into three basic categories: patent, latent, and plastic. A tool mark is any impression, scratch or abrasion made when contact occurs between a tool and an object. The impressions made by these tools could link the tool to a crime scene and ultimately to the tools owner. A significant part of studying firearms involves examining used bullets and their spent cartridge casings for individualizing markings left on then by the firearm that shot them.

Analyze data to support the claim that Newton s second law of motion describes the mathematical relationship among the net force of a macroscopic object, tis mass, and its acceleration. Use mathematical representations to support the claim that the total momentum of a system of objects is conserved when there is not net force on the system. Apply scientific and engineering ideas to design, evaluate and refine a device minimizes the force on a macroscopic object during a collision. Use mathematical representations of Newton s Law of Gravitation and Coulomb s Law to describe and predict the gravitational and electrostatic forces between objects.
