1.1

Question 1

Forensic Science

Answer 1

The application of scientific knowledge to resolve questions of civil and criminal law.

Question 2

Link Method

Answer 2

Method seeking to find associations between evidence. Investigators evaluate the scene and then proceed through the area in a systematic and logical fashion. Based on the notion that one type of evidence leads to another. Works with large and small, indoor and outdoor crime scenes.

Question 3

Line (Strip) Method

Answer 3

Used on large, outdoor crime scenes. Members of the search team are arranged at regular intervals, usually arm’s length, and then proceed to search along straight lines.

Question 4

Grid Method

Answer 4

Used on large, outdoor crime scenes. Searchers follow the first line pattern and search in the same manner as the line method. Once the first line pattern is complete, searchers realign on the other line pattern.

Question 5

Zone Method

Answer 5

Used on crime scenes that are comprised of readily definable zones, such as in houses or buildings. Teams are assigned small zones for searching, and then other appropriate searching methods are employed in each zone.

Question 6

Spiral Method

Answer 6

Used on crime scenes with no physical barriers, such as open water. Can either begin at critical point of crime scene (outward spiral) or the outer-edge of the crime scene (inward spiral).

Question 7

Wheel or Ray Method

Answer 7

Used on small, circular crime scenes. Investigators start from a critical point and travel outward along many straight lines from this point.

Question 8

Person of Interest

Answer 8

A person of interest is someone who law enforcement thinks may have information related to a possible crime

Question 9

Polygraph Test

Answer 9

Polygraph tests, commonly known as lie detector tests, are sometimes used in forensic cases to help determine the truthfulness of someone who may be connected to a possible crime.

Question 10

Heart Rate

Answer 10

Polygraph tests, commonly known as lie detector tests, are sometimes used in forensic cases to help determine the truthfulness of someone who may be connected to a possible crime.

Question 11

Blood Pressure

Answer 11

The pressure exerted by the blood upon the walls of the blood vessels

Question 12

Respiration Rate

Answer 12

How many breaths you take in one minute

Question 13

Skin Conductivity

Answer 13

How the amount of sweat produced impacts the ability to conduct electricity

Question 14

Vital Signs

Answer 14

Measurements—specifically pulse rate, temperature, respiration rate, and blood pressure—that indicate the state of a patient’s essential body functions.

Question 15

Pulse

Answer 15

The rhythmic expansion and recoil of arteries resulting from heart contraction.

Question 16

Control

Answer 16

The group in an experiment where the independent variable being tested is not applied.

Question 17

Experiment

Answer 17

A research study conducted to understand an observed phenomenon; determines the effect that one variable has upon another variable.

Question 18

Hypothesis

Answer 18

A statement predicting the anticipated results of an experiment.

Question 19

Experimental Design

Answer 19

A process used to carefully plan experiments in order to investigate scientific questions or problems.

Question 20

Iterative

Answer 20

Repeating a series of steps over and over until the desired outcome is obtained.

Question 21

Independent Variables

Answer 21

In an experiment, the variable that the researcher intentionally changes to determine its influence on the dependent variable.

Question 22

Dependent Variables

Answer 22

In an experiment, the variable being measured and whose value is influenced by another variable.

Question 23

Trace Evidence

Answer 23

Tiny fragments of physical evidence, such as hairs, fibers from clothing or carpeting, and pieces of glass.

Question 24

Cortex (hair)

Answer 24

The cortex is home to the pigment-containing granules responsible for hair color and contains many of the characteristics used in the microscopic analysis of hair.

Question 25

Medulla (hair)

Answer 25

Finally, the innermost layer of hair is called the medulla. This layer may be continuous, discontinuous, fragmentary, or even absent

Question 26

Cuticle (hair)

Answer 26

The cuticle is the outermost layer of the hair. It is consists of flattened, scale-like cells which overlap one another

Question 27

Arch Patterns

Answer 27

When the lines in your fingerprints arch upwards

Question 28

Loop Patterns

Answer 28

The loop patterns form when rides curve back on themselves forming a loop shape

Question 29

Whorl Patterns

Answer 29

circular or spiral patterns
