Processing a Crime Scence

Drowning

CDC Definition
CDC data about incidents of "dry drowning." CDC supports international consensus defining drowning as "the process of experiencing respiratory impairment from submersion/immersion in liquid" and does not distinguish between "wet" and "dry" drowning.
World Health Organization Definition
Drowning is defined as death by suffocation due to being immersed in water. There are two classifications of drowning: wet and dry. In wet drowning, the person has inhaled water which interferes with respiration and causes the circulatory system to collapse. In the less common instance of dry drowning, the airway closes up due to spasms caused by the presence of water. Near drowning may result in neurological damage and successful recovery depends on prompt rescue and resuscitation.
How big is the problem?
The following information was gathered from CDC:
In 2005, there were 3,582 fatal unintentional drownings in the United States, averaging ten deaths per day. An additional 710 people died, from drowning and other causes, in boating-related incidents.

Cont…..
More than one in four fatal drowning victims are children 14 and younger.1 For every child who dies from drowning, another four received emergency department care for nonfatal submersion injuries.
Nonfatal drownings can cause brain damage that may result in long-term disabilities including memory problems, learning disabilities, and permanent loss of basic functioning (i.e., permanent vegetative state).
What situations commonly lead to a near drowning?
* Near drownings are very common accidents.
* Children can drown in just a couple inches of water.
* A child can drown in seconds.
* A drowning can happen anytime a child is left alone around water.
* A drowning can happen in a bathtub, child bathing seat, or sink.
* A drowning can happen in a bucket or toilet.
* A drowning can happen in a pool, hot tub, lake, river, ocean, etc.
* A drowning can happen while boating or fishing.
* Drownings that involve alcohol are common.
* A drowning can happen after falling through ice.
What is happening?
While you struggle to breathe, you force water into your sinuses. Coughing triggers an inhalation reflex, which pulls more water in to the lungs. The loss of air supply leads to unconsciousness. The heart stops shortly after. Any amount of water in your airway can cause a laryngospasm. Once that has occurred the airway can seal and lead to cardiac arrest because of oxygen deprivation. Some call this a “dry” drowning.
Fresh V.S. Salt
No difference in the mechanism of drowning. There are clues concerning whether the person drowned in fresh water or salt water.

9. Aorta (to body)
capillaries of the body

Homework:
Quiz Thursday

Cells

Finish Cell Drawing
Why is mtDNA more useful in identifying remains than nuclear DNA?
The other approach analyzes mitochondrial DNA, or mtDNA. Because mtDNA tends to survive long after nuclear DNA has disintegrated, this approach is useful in identifying the remains of persons who died long ago. It was used, for example, to identify the two crew members of Bomber 31 who have been identified and, more famously, to help identify Czar Nicholas II of Russia, who was killed along with his immediate family in 1918. This is also the technique scholars have turned to in order to assess how closely related extinct Neanderthals are to people today*. Also, there are more copies of mtDNA than nuclear DNA (200-2,000 mitochondria v.s. 1 nucleus). http://www.pbs.org/wgbh/nova/bomber/mtdna.html

During Drowning, wet or dry, what is happening to the cells in your body? Answer in your lab notebook.
(Hint: Where does the oxygen go?)

The donations are non-mandatory. However, if you are able to donate to the science department all faculty members would be grateful and your donations will be well utilized. Thank you for considering helping your school science program. Mrs. Marshall

Sketching a Crime Scene

Sketches and photography work together, with the sketches giving perspective to the photographs. The sketches give measurements, scale and relative placement of all important details in the crime scene. An original sketch is considered evidence and must never be changed or tampered with.
Today in class we went over fixed points and how to measure objects from these fixed points.

Course Syllabus

Forensic Biology
2008/2009

Instructor: Mrs. Marshall
Email: kmarshall@juhsd.net

Course Description:

Forensic Biology is a one-year college preparatory course based on California State Content Standards for biology. The class is designed to provide knowledge and information, as well as build skills in the conduct of science in the context of forensics. Students will be assessed in a variety of ways; a portion of their evaluation will include testing their ability to conduct laboratory investigations to solve crimes using scientific knowledge, accrued experience, and critical thinking skills. Assessment will be based on individual and team achievement. The areas of biology that we will cover during the year specifically include cell biology, genetics, ecology, human physiology, and related subject matter. The course will utilize basic laboratory skills to reinforce student understanding of science, and engender the student’s confidence in thinking and doing science.

Grading Policy:
Grades will be given based on work completed by each student and will reflect their participation in class and the effort devoted to completing assignments and taking examinations. Students will earn their grades based on the points received in the categories listed in class requirements. My sentiment regarding grades is that they are “earned” and not “given.” Grades are based on the following scale:

90-100 A
80-89 B
70-79 C
60-69 D
<59 is not passing

Class requirements:
Homework assignments
Laboratory notebook
Quizzes/Unit Tests (I allow only one make up test)
Participation including punctuality, class activities, assignments, and respect for others

Late assignments will only be accepted if the absence is excused by the attendance office. All make up work must be handled after school and not during class time.

*Seniors must take their spring final exam during the scheduled time or take a zero.

Policies and Classroom Guidelines:

Tardiness:
Students must be in their seats before the bell, or they will be considered tardy. I expect tardy students to meet with me after school, for any work missed.

Electronic items in the Classroom:
Do not bring personal electronic items, including but not limited to cell phones, iPods, handheld games, if I confiscate such items, they will be turned into the office. No exceptions.

Food and Drink:
Water only.

Concerning behavior; the school has a very clearly stated set of guidelines that will be scrupulously maintained in my classroom. I shall make every possible effort to ensure the success of each student.

Required Materials:
Composition book (bound notebook), glue stick, working pen and pencil.

Course Textbooks:
Miller and Levine. Biology
Deslich and Funkhouser. Forensic Science for High School

Course Notebook:
With the exception of tests and quizzes, all other coursework will be completed in the laboratory notebook. It is essential that the notebook be brought to each class meeting, along with a working pen or pencil and glue stick.

My availability:
After school.

I look forward to an exciting and fulfilling year with you!

I have read and understand the class requirements, and my obligations and responsibilities.
