Forensic Science: Introduction to DNA Fingerprinting
Students get a real feel for what it takes to be a modern-day detective in this basic introduction to forensic science. The first activity begins with a crime scene and the identification of suspects based on an eyewitness report and "video stills" of the crime in progress. "Physical evidence" found at the scene of the crime is scientifically analyzed. This kit provides an introduction to cells, cell structure, and magnification. Students use this information to construct a "chromosome" model with color-coded "genes" representing some physical traits of the suspects. The process of DNA mapping and DNA fingerprinting is carefully explained. Students then read simulated DNA x-ray films to positively identify the perpetrators of the crime. Material in this kit is reusable.
