Forensic Science

If a burglar breaks into a house, they will leave behind traces such as fingerprints or shoe prints that can be used as evidence. This exemplifies Locard's principle that every contact leaves a trace, meaning that whenever two objects come into contact, there will be an exchange of material that can be detected.

The only way to permanently ruin a fingerprint would be to damage the underlying dermal tissue through severe burns or deep cuts that prevent the ridges from regenerating properly. Additionally, some medical conditions such as leprosy or certain skin diseases can also cause permanent damage to fingerprints.

Flame tests are used in a wide range of environments. I.e, In construction and construction materials to assess at what stage a material used will actually catch fire. In many cases the test is used for fire prevention. In furniture, most countries now have a formal fire resistant level required to build and retail furniture.

William Herschel - an astronomer known for discovering Uranus and infrared radiation, but did not contribute to forensic toxicology.

Blood stains are typically easier to detect using forensic light, as they contain hemoglobin that fluoresces when exposed to certain wavelengths of light. This fluorescence can make blood stains stand out more visibly against different surfaces.

One way to test if a powder is talc or cornstarch is by performing a iodine test. Mix the powder with iodine solution; if the mixture turns blue-black, it is likely cornstarch. Another way is to do a simple solubility test: dissolve the powder in water and if it is talc, it will not dissolve and settle to the bottom, while cornstarch will dissolve.

They are typically referred to as "forensic evidence" or "crime scene evidence." These documents can include things like photographs, maps, diagrams, witness statements, and any other materials that could provide insight into a crime.

Laboratory technicians in a crime scene are responsible for collecting, analyzing, and interpreting physical evidence found at the scene. They may take photographs, document evidence, process samples, and perform various tests to assist in solving the crime. Their findings are crucial in providing verifiable scientific evidence for criminal investigations.

Ultimately the Court qualifies a forensic chemist. They take into account education and experience along with certifications from certain bodies such as ASCLAD-LAB and results of proficiency tests performed by that individual.

Yes, Scene of Crime Officers (SOCOs) are considered forensic scientists as they are responsible for collecting and preserving evidence at crime scenes for analysis in the laboratory. They play a crucial role in the forensic investigation process.

It is a type of scince that works with DNA and evidnce to help solve a crime!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! It is reall coo, i want to be a forensic when i growup!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!:)

Anything is possible, but, this mechanics make it highly unlikely anyone would attempt it.

Actually, to some extent, gunpowder and dynamite overlap. Dynamite was originally made by using an inert material to soak up and hold nitroglycerin. Modern smokeless gunpowder is usually a mix of 2 explosives- nitrocellulose and nitroglycerin, and a filler material. Incidentally, from about 1880 to 1900, the US used a type of cannon called a Dynamite Gun. It fired a shell filled with dynamite or similar explosive, using compressed air to drive the shell.

CSI can use DNA samples to link a suspect to a crime scene or victim. By analyzing the unique DNA profile from a sample, investigators can identify individuals with a high degree of accuracy. This helps in solving crimes and providing evidence for prosecution.

A photographer should follow crime scene protocol, which includes not tampering with the body or surroundings. They should document the scene as it is and inform the authorities immediately. It is important to respect the deceased and the integrity of the investigation.

The rate at which the body's temperature drops after death can vary widely depending on factors such as the ambient temperature, clothing, and body size. Typically, the body's temperature can drop by around 1.5 degrees Fahrenheit per hour in the first 12 hours after death.

The greatest challenge to forensic science isn't any one drug, but a combination of drugs and chemicals and their complex reactions. The longer the drug remains in the body, the more it is metabolized into another substance.

Microscopes play a critical role in forensic chemistry by allowing analysts to examine trace evidence such as fibers, hairs, and glass fragments. This level of detail can provide crucial information for identifying suspects, linking evidence to crime scenes, and ultimately solving cases. The use of microscopes helps in the accurate analysis and interpretation of evidence, leading to more reliable forensic conclusions.

Fingerprints are made visible by the natural oils and sweat present on the ridges of the skin. When a person touches a surface, these oils and sweat are transferred, leaving a print that can be developed using techniques such as dusting, chemical processing, or photography.

Investigators can use the angle of impact of blood spatter to help determine the direction from which the blood originated. By analyzing the angle, they can reconstruct the events that led to the blood spatter, helping to establish the position and movement of individuals involved in the crime. This information can provide crucial evidence to support or challenge witness statements and suspects' alibis.

A group of associated fields is called a record. Each field within the record stores specific information related to a single entity or object. Together, the fields form a cohesive set of data that represents a complete unit of information.

1. Take a jar and fill it up with the blood.

2. Tell everyone you committed the crime.

3. Show the police.

4. Hide the body in your neighbors trashcan.

5. Wate until the trash truck comes.

6. Then you will feel guilty.

The lab will compare markings on the bullet with test fires from the suspect weapon. They use a comparison microscope to analyze striations and grooves left on the bullet. If there's a match in these markings, it suggests the bullet came from the suspect weapon.

Atomic absorption is used in forensics to analyze trace elements in samples such as blood, hair, or soil. By measuring the absorption of specific wavelengths of light by the atoms in the sample, atomic absorption spectroscopy can determine the presence and concentration of elements like arsenic, lead, or mercury, which can be crucial in solving criminal cases.

Evidence of a gunshot wound includes a wound with an entry and exit point, damage to surrounding tissue, blood loss, and potential presence of gunpowder residue. X-rays may also reveal the presence of bullet fragments. An autopsy may provide further details on the trajectory of the bullet and internal damage caused.

Forensic Science is the application of scientific methods and techniques to analyze and interpret physical evidence in criminal investigations. It involves using scientific principles to solve crimes and provide evidence for legal proceedings.
