Forensic science is a kind of science that blends biology, chemistry and physics to look at evidence, solve crimes and settle legal issues. Forensic scientists use evidence like fingerprints ...
The Grades 6-12 level book provides labs on life, physical, and earth science as well as critical thinking. Like real-life forensic scientists, students observe carefully, organize, and record data, think critically, and conduct simple tests to solve crimes …
Science Project: Forensic Science Experiments Study a Crime Scene of Your Own. See how many clues you can identify in your own “crime scene.” Choose a room (e.g., kitchen, living room, bedroom) or part of a room and go over it carefully, finding any trace evidence such as hair, clothing fibers, and chips of paint. You can collect these with a pair of tweezers and place them …
Finding clues, connecting the dots, and solving mysteries are all part of forensic science and crime scene investigation. One of the most important aspects of forensic science is the preservation of evidence. Making sure the evidence is kept safe and intact is important so that investigators can reconstruct what happened and glean clues from the evidence. You might be …

Forensic science is based on the principle that a person always brings something to a crime scene and also leaves something behind. Forensic science uses science to solve legal issues within the civic and criminal justice systems. Forensic scientists collect physical and chemical evidence from crime scenes and then analyze ...
Well, because television shows have been known to stretch the truth, there is something called the “CSI Effect” where the public has inaccurate expectations of what forensics really is based on the media’s portrayal of it. Your job, then, is to help your child “discover” the truth about forensic science.
Biometrics include fingerprints, facial features, retinal patterns, and handwriting. Chromatography: A method of identifying different inks by the unique pigment combinations found in inks. DNA: Basic unit of a person’s genetic information, which is used to determine a person’s identity.
Forensic scientists don’t just work at crime investigations. They play a key role in understanding anthropological and archaeological finds , such as the so-called ice people and bog people – ancient bodies found either frozen or preserved in bogs. Both bogs and ice prevent bacteria growth that would rot bodies. Bogs also contains acids that tan a body’s skin like leather. Once these naturally-mummified bodies are found, scientists examine them for clues to their past. Did they die violent deaths? What did they eat? What did they do for a living? Forensics can help answer these questions, although sometimes the evidence is not enough to make conclusive judgments.
Crime scene investigation has developed since Sherlock Holmes’ day, although careful examination of evidence is just as important today! The science that deals with crime investigation, or science that is applied to law cases, is called forensic science.
You can use a small paint or makeup brush with very soft bristles to gently swipe off the excess powder and leave the print.
Chromatography is used to identify different inks. Say someone committed a crime by changing the dollar amount on a check. Using chromatography, an investigator could tell whether more than one ink pen was used to write on the check and whether the suspect’s ink pen could have been used.

While DNA is not quite as unique as a fingerprint because it can be shared between identical twins, it’s much easier to collect and test. Fingerprints can be hard to collect and analyze because they can be incomplete or smudged, but DNA can be found in almost anything a person can leave behind.
Forensic science is used to help show the legal evidence that would be presented in court when a crime has been committed.
Forensics Illustrated is a free comprehensive, complete forensic science curriculum created for high school students from Brennon Sapp. He taught highschool forensic science for 9 years and compiled all of his information online for anyone for free.

Some of the most important evidence in a criminal investigation comes from the things people see and hear. Police always appeal for witnesses (people who have observed events before and after crimes take place), both to help them establish what has happened and to find out who was responsible. In complex cases, detectives can find themselves interviewing hundreds or even thousands of witnesses. All these statements (the written descriptions of what people say they saw or heard) have to be checked and compared. To complicate matters further, statements often disagree because people don't always remember events accurately—especially in stressful situations or if a long time has elapsed between the crime being committed and the police asking questions.
Sherlock Holmes, the famous fictional detective from London's Baker Street, relied on his powers of observation and deduction to solve crimes that baffled the police. But in the real world, it's often forensic scientists, working diligently out of the spotlight, who provide the crucial pieces of evidence.
Their job is to find every single piece of evidence, no matter how small, and take samples away for further investigation.
A crime scene is the place where a crime is discovered— but it's not necessarily the place where the crime was committed. When people murder, they often kill in one place but dispose of the body in an entirely different location in an attempt to conceal what they've done.
Serial killers (murderers who carry out a series of attacks) may kill and dispose of people in many different locations. In this case, the crime scene (the place where a body is discovered) typically contains less useful evidence, and the body recovered from the scene is where the forensic scientists focus their search for clues. ...
The human body is made from soft tissues built on a strong skeleton of bones. The tissues disintegrate quite quickly after death, which can make identifying a victim very difficult. Often detectives have to use dental records and DNA (the person's genetic material) to confirm who a person is.
Course content can become outdated quite quickly. After analysing 71,530 courses, we found that the highest rated courses are updated every year. If a course has not been updated for more than 2 years, you should carefully evaluate the course before enrolling.
We analyzed factors such as the rating (4.9/5) and the ratio between the number of reviews and the number of students, which is a great signal of student commitment.
The course includes 12h 28m video content. Courses with more videos usually have a higher average rating. We have found that the sweet spot is 16 hours of video, which is long enough to teach a topic comprehensively, but not overwhelming. Courses over 16 hours of video gets the maximum score.
We have all seen forensic scientists in TV shows, but how do they really work? What is the science behind their work?
