Fingerprints
These are the 4 fingerprint pattern types.
What is a loop, whorl, arch and composite type?
This is the measurement from the heel of one print to the toe of the next?
What is stride length?
This happens when you place a water soluble maker on a coffee filter or chromatography strip and place the strip in water.
What is the ink will rise and the different colors will separate?
This is when investigators use their senses to record information about a scene.
What are observations?
These individuals may have seen, or heard something to do with a crime being committed. Their information can be valuable to a case.
Who are witnessess?
These are the 4 ridge characteristics.
What are: Bifurcation, Lakes, Forks, Islands?
A set of tracks that has very spaced out footprints and wide stride lengths could be someone who was...?
What is running?
This would be the responding variable in an ink chromatography lab.
What is the different colors that show up and the distance the colors travel up the strip?
This is a way of organizing information or materials by a chosen characteristic.
What is classify/classification?
These are two possible ways to conduct a fabric test.
What are: stretch test, colorfastness test, absorbency test, wrinkle test, tread test?
This type is like a wave or a hill. The ridges enter one side of the print, rise in the middle and exit on the opposite side of the print.
What is an Arch?
Give three things that a footprint/ animal track can tell an investigator.
What are the size of person/animal, direction of travel, how many are moving, the speed of travel, the weight and height, and type of animal
The amount of water used, type of marker, container size. These all make up this section of a lab report. (Need to be specific)
What are controlled variables?
This is a clue that is left behind from something or someone at a crime scene.
What is evidence?
Man-made fibers are more likely to__________than natural fibers.
What is more likely to melt and give off noxious fumes?
This is when a fingerprint ridge the splits off into two distinct ridges.
What is bifurcation?
One way to collect of footprint is?
What is a rubbing, casting, photograph, electro static lifting?
Chromatography & Graphology are useful in crime scene analysis for this reason.
What is they can tell who wrote a note if one is left at a crime seen or what pen was used to write the note?
To try to find out the facts about something in order to learn how it happened.

What is a larger and smaller?
Name 3 helpful things to look for when analyzing a handwriting sample.
What is/are: Spacing and slant of the letters, Spacing , Pressure on the page, Formation of letters and loops , Dotting, Crossing, How letters are joined, Combination of printing and writing, Size, Extra marks on the page, Writing tool used?
This is explanation of an observation that is plausible based on observations.
What is an inference?
These are the characteristics that we can use to identify and classify types of soil. (Name 3)
What are: color, texture, odor, content, particle size, water solubility?
