Crime Scene Investigation
5th Grade CSI: Forensic Science After-School Enrichment Class
Students learn how to analyze evidence just like a forensic scientist! We practice our skills by using circumstances that model real life events. Each class will feature a hands-on lab such as: taking and analyzing fingerprints, chromatography, creating and deciphering codes, analyzing trace evidence, hair and fiber analysis and so much more!
Fingerprinting
Fingerprints are unique patterns, made by friction ridges (raised) and furrows (recessed), which appear on the pads of the fingers and thumbs. The fingerprint pattern, such as the print left when an inked finger is pressed onto paper, is that of the friction ridges on that particular finger.
DNA Extraction
___
Since DNA is the blueprint for life, everything living contains DNA. DNA isolation is one of the most basic and essential techniques in the study of DNA. The extraction of DNA from cells and its purification are of primary importance to the field of biotechnology and forensics. DNA can be extracted from many types of cells.
Soil Analysis
___
Forensic Soil Analysis is the use of soil sciences and other disciplines to aid in criminal investigation. Soils are like fingerprints because every type of soil that exists has unique properties that act as identification markers. This means that the origin of the soil sample can be identified.
Blood Typing
___
This blood typing lab encourages students to determine blood types using Anti-A serums, Anti-B serums, and Anti Rh serums. They used a chart to help determine the blood type of each sample and its Rh factor (+ or -).
Hair Analysis
___
Hair and fiber are two of the most important resources in Forensic Science and are often responsible for providing valuable clues as to the identity of an assailant or attacker.
Document Analysis
___
Handwriting analysis is a tedious and methodical process that relies on extensive knowledge of the way people form letters, which characteristics of letter formation are unique and the physiological processes behind writing - the ways in which a person's fine-motor skills can affect his or her handwriting and leave clues about the author's identity.
Chromatography
___
Chromatography is a method for analyzing mixtures by separating them into the chemicals from which they are made. In ink chromatography, you are separating the colored pigments that make up the color of the pen.
