Unit 6 Assignment: Analytical Techniques Essay
The scientific method emphasizes the use of precision,
objectivity, critical thinking, careful observation, practice,
repeatability, uncertainty management, and peer review, which
enables the reliable collection, measurement and interpretation
of clues in order to produce knowledge.
In 750- to 1,000- words, summarize how the scientific method
governs the way forensic scientists conduct qualitative and
quantitative analysis of physical evidence containing organic
and inorganic matter. Include the following:
·
Explain the information gleaned by the forensic scientist in the
process of conducting both qualitative and quantitative analysis
of physical evidence.
·
Differentiate between organic matter and inorganic matter.
(Each analytical technique used to examine organic and
inorganic matter has its benefits and limitations.)
·
Provide examples of physical evidence containing organic
matter and evidence containing inorganic matter.
·

3. Address the following questions:
o
What combination of analytical procedures would a forensic
scientist use when identifying physical evidence to ensure that
accurate and reliable scientific results are obtained? (The
conclusions and opinions expressed by forensic scientists are
subject to scrutiny through the judicial process.)
o
How would a forensic scientist defend his or her scientific
conclusions and opinions in a court of law?

Superglue Fuming Safety Measures-This week in Seminar, you
will be taking a comprehensive look at superglue fuming
including safety measures, proper equipment, and enhancement
techniques. When would the technique of superglue fuming be
appropriate to use? What are the drawbacks of using superglue
fuming techniques?
Assignment
Assignment 2: Fingerprint Processing
You will process a variety of porous and nonporous items for
latent prints using black fingerprint powder or crushed charcoal.
Describe your experience in a 300–500-word essay, addressing
the following questions:
·
How many different prints or partial prints did you locate?
·
What types of objects did you lift the prints from? Where were
they located?
·
What supplies did you use? What technique did you use to apply
the powder?
·

5. Did you expect to find more prints, or fewer?
·
Can you identify the prints as different from one another? How?
It is very important to pick a variety of different surfaces for
this Assignment. Please attempt at least 5–10 different types of
surfaces (porous and nonporous).
What are some types of surfaces that you would expect to find
fingerprints on?
·
Microwave, oven, door knob, window, sliding-glass door,
bathroom mirror, toilet seat, paper items around the house, cars,
soda cans, bowls and dishes, glasses, etc.
Your paper should be longer than 300 words. Provide as many
details about your successes and failures as you can.
