Forensic Science Quiz

A voice print is a visual representation of a person's voice, often used in forensics to analyze pitch, loudness, and other characteristics over time.

Evidence is any item or information presented in court to help prove or disprove a fact in a legal case.

Skid marks are the dark, rubbery marks left on a road surface when a vehicle's tires stop rotating while the vehicle is still in motion.

Recording a crime scene involves documenting the scene through photography, video, and sketches before any evidence is moved or collected.

Tool marks are impressions, scratches, or abrasions left on an object by a harder tool used to force entry or manipulate an object.

An imprint is a two-dimensional mark left by an object on a surface, such as a footprint on a floor or a tire mark on pavement.

Document analysis is the forensic examination of documents to determine authenticity, detect alterations, or identify the author.

A Crime Scene Investigator (CSI) is a professional trained to identify, document, collect, and preserve physical evidence at a crime scene.

Fingerprints are the unique patterns of ridges and valleys on the skin of the fingertips, which leave distinct impressions when touching surfaces.

A hypothesis is a testable, educated guess based on prior knowledge or observations. It serves as the starting point for scientific investigation.

A shoe print is the pattern left when a shoe presses against a surface. Casts are three-dimensional molds, skid marks are from tires sliding, and the D option is misspelled (should be Impression). Shoe prints are a type of impression evidence.

Document analysis is the forensic field dedicated to examining documents to determine authenticity, origin, or alterations. It encompasses handwriting, ink, and paper analysis.

A print is a general term for a mark created when an object is pressed against a surface. While 'impression' is similar, 'print' is the most common term for this specific definition in basic forensics.

Trace evidence refers to minute amounts of physical or biological material found at a crime scene. It is crucial for linking suspects to locations or victims.

A cast is created by pouring a liquid material, such as plaster, into an impression to create a three-dimensional replica. This is commonly used to preserve evidence like footprints.

The chain of custody is a chronological documentation or paper trail that records the sequence of custody, control, transfer, and analysis of physical evidence.

Chromatography is a laboratory technique used to separate the components of a mixture based on their different rates of movement through a stationary phase.

An impression is a three-dimensional mark left when an object is pressed into a softer surface. Unlike a two-dimensional print, it retains depth.

A prediction is a statement about what is expected to happen in the future based on current information or patterns.

An inference is a logical interpretation or explanation based on prior knowledge and observations. It goes beyond the raw observation itself.

An observation is the act of gathering information about the world using the five senses. It is the fundamental step in scientific inquiry.

Forensics is the application of scientific principles and techniques to investigate crimes and answer legal questions.
