Each person in the world has a set of fingerprints unique to them! Even though every print is different, they can be categorized into one of three general types: -loops (found in 65% of the population) -whorls (found in 35% of the population) -arches (found in 5% of the population)
Analyzing fingerprints can be a tricky business, especially without computers to help. After categorizing a print as a loop, whorl, or arch, look for these individual features: -core: in a loop fingerprint, this is the center of the loop. -delta: in loop and whorl patterns, this is an area where ridges meet from three directions. (There is usually one delta on a loop and two or more on a whorl. -ridge end: notice where individual ridges come to an end. -bifurcation: notice where a ridge divides into two ridges (like a fork in a road) -island: notice any short ridges cut off from others. -crossover: notice where any ridges appear to cross over each other.
Try your hand at fingerprint analysis! Two different fingerprints have been found at a crime scene. Compare them to the fingerprints of the 4 suspects on this website.

-Arson and explosions often present complex and difficult circumstances to investigate due to the fact that the perpetrator has thoroughly planned the act, is not present during the act, and the destruction is so extensive. -The criminalist’s function is rather limited to detecting and identifying relevant chemical materials collected at the scene and reconstructing and identifying ignitorsor detonating mechanisms.

Forensic Science is the application of the scientific method to solving mysteries. Forensic scientists draw on skills from a number of disciplines in order to gather evidence and draw conclusions about an event. Teachers may use the subject of forensic science to stimulate interest in the various disciplines of science among their students. The discipline is particularly useful in the classroom because it emphasizes hands-on learning and gives students the opportunity to develop their reasoning skills. Many of the activities on this site use computers and computational science. Such methods are useful to forensic scientists because they allow scientists to view evidence with greater clarity, to simulate specific events and to save time by automating tedious processes.

This free course, Forensic science and fingerprints, covers how science can make fingerprints easier to study, how they are used in court and some of the questions about the extent to which fingerprint identification is sound and scientific. Students will learn the principles used in classifying and matching fingerprints (often called marks).
Course learning outcomes...After studying this course, you should be able to:
demonstrate knowledge and understanding of some of the basic facts, language, concepts and principles relating to the principles and significance of fingerprint matching demonstrate knowledge and understanding of some of the links between forensic science and the legal system draw together information from different sources and make logical deductions as a result demonstrate an understanding of how forensic scientists operate and use scientific evidence in a legal context.

The course addresses four major evidence types: drugs of abuse, DNA, firearms and impression evidence, and discusses these through the exploration of a case-based scenario presented across a six-week modular framework.
A murder case set on the murky shores of Loch Lomond provides the backbone to the course. As the case unfolds each week, a number of evidence types, and the forensic science approaches that may be used to evaluate the evidence, are explored. All will be revealed in the final week, so make sure you are there to find out the identity of the murderer!
No special knowledge or previous experience of studying is required. Warning: Some of content presented in this course may be distressing to individuals, particularly younger learners. Notwithstanding, the material is representative of that encountered by forensic scientists and we have presented it in an objective and professional manner.
Taught by Jim Fraser
You have free access to this course for 8 weeks! Paid options are available too.

On TV shows like "CSI," viewers get to watch as investigators find and collect evidence at the scene of a crime, making blood appear as if by magic and swabbing every mouth in the vicinity. Many of us believe we have a pretty good grip on the process, and rumor has it criminals are getting a jump on the good guys using tips they pick up from these shows about forensics.
But does Hollywood get it right? Do crime scene investigators follow their DNA samples into the lab? Do they interview suspects and catch the bad guys, or is their job all about collecting physical evidence? In this article, we'll examine what really goes on when a CSI "processes a crime scene" and get a real-world view of crime scene investigation from a primary scene responder with the Colorado Bureau of Investigation.

Forensic anthropology is the application of anthropology to criminal investigations. It incorporates concepts and methods from biological anthropology (the study of the physical aspects of humanity). Identifying unknown individuals is a key part of forensic anthropology. Anthropologists assist in identifications primarily by constructing a biological profile. This includes estimating age, sex, stature, and ancestry, as well as identifying specific characteristics, like diseases or injuries. In addition to helping identify human remains, the anthropologist analyzes injuries that happened around the time of a person's death, which can help determine how a person died. To do these things, an anthropologist begins by asking a series of important questions.

A criminal case has just been opened. Your task is to help close it. Have you ever wondered how forensic science works? You may have seen police and crime lab work on television but what is a real forensic science investigation like? This site includes information and activities that recreate some of the challenges forensics experts deal with. You will learn first-hand about forensics by taking on the roles of Forensic Archaeologists, Anthropologists, Entomologists, Botanists, DNA Analysts, and Stable Isotope Analysts. Each of your tasks will be a real job that a forensic expert does and every step is important to solving the case. Think carefully, but if you get stuck there are hints to help you. Additionally, there are expert videos on each discipline, photographs of practising forensic scientists at work in the field and in the lab, and a detailed textual library in the "Resources" section. Links to these resources occur at the end of each activity.

We touch things every day: a coffee cup, a car door, a computer keyboard. Each time we do, it is likely that we leave behind our unique signature- in our fingerprints.
No two people have exactly the same fingerprints. Even identical twins, with identical DNA, have different fingerprints. This uniqueness allows fingerprints to be used in all sorts of ways, including for background checks, biometric security, mass disaster identification, and of course, in criminal situations.
Fingerprint analysis has been used to identify suspects and solve crimes for more than 100 years, and it remains an extremely valuable took for law enforcement. Once of the more important uses for fingerprints is to help investigators link one crime scene to another involving the same person. Fingerprint identification also helps investigators to track a criminal's record, their previous arrests and convictions, to aid in sentencing, probation, parole and pardoning decisions.

A forensic scientist enters a crime scene and sees some flies, maggots, and a few beetles on and around a dead body. She immediately begins collecting them. Why? Because these insects can help investigators solve crimes! The type and ages of insects found at a crime scene can help investigators determine how long a body has been lying there, for instance, and if the victim had taken any drugs, medications, or poison before death. Our understanding of the clues that insects can provide about a crime scene comes from research done at facilities called body farms. At these facilities, forensic scientists study how bodies decompose, and forensic entomologists study the insects that contribute to that decomposition. In this activity, you will create your own mini-body farm to attract insects to a “corpse” (in this case, a piece of meat). Over the course of a week, you will observe the number and types of insects that arrive at your corpse. You’ll use that data to explore how crime scene conditions affect the decomposition of a corpse.
