Firearms and Ballistics

Firearms Identification

Go to www.firearmsid.com. On the left side under ‘classroom’ click on student login. Use the log-in key I told you in class and type in your full name. Click accept. In the classroom area you (each individual) must complete the following tasks:

1. Complete the Cartridge Case ID-VCM (Test 1).  You must score a 75% or better. **
2. Complete the Firearm Identification quiz (50 questions) located here.  You must score an 80% or better.**  Use your real name on the page.  When you score an 80% or better, print the results page as proof and bring it to class to show me.
3. Complete the Bullet ID-VCM (Test 1).  You must score a 75% or better.**
4. Answer the questions below.

** – if you do not obtain the above scores you will receive a zero.  You may take the quiz/VCM more than once until you obtain the necessary score. This is an all or nothing assignment.

To answer the following questions you should read the information on the site. If you click on the Bullet ID-VCM link and the Cartridge Case ID-VCM link the resultant pages list several links to find the necessary information.

Nutrition and Why We Need to Eat

Complete the following to learn some nutrition facts and why we need to eat…

  1. Take the PCRM nutrition quiz.
  2. Complete the “Why Do We Need to Eat?” handout given in class.
    1. Create a Google spreadsheet and share it with me (cswfleetwood).
    2. Name the document as follows: period_letter last_name first_name Nutrition Information
      1. ex:    G Fleetwood Thomas Nutrition Information
    3. Fill in all the necessary information as shown on the handout.
      1. You can make more rows as necessary for all the vitamins and minerals – they don’t all fit in one box like on the handout
  3. Research the question, “Is drinking milk good or bad for us?”  Type a one page summary on a new tab in the spreadsheet you created in #2 above.  Be sure to include studies and citations.

A copy of the handout can be found here.

Due: Tuesday, 2/4/14

Skeletal Practical 2014

Your skeletal practical will be based on your signup date/time on the sheet in the classroom.  The available dates are 2/19 – 2/21/14.  These dates are a Wednesday, Thursday and Friday.  The practical will consist of 3 identification questions (using bones I have in class) based on the bone list given in class and then you will build either a hand/wrist/arm or a foot/ankle/leg.  I will assign you one of them during the practical – you will not know which before-hand, so practice (a lot) with both.  After you build the upper or lower limb, you will name all the bones.  You do not need to name the parts of each bone (e.g. tibial tuberosity), just the name of the bones.  You will have 4 minutes and 30 seconds to complete the entire practical (3 questions, build and name).

Practical dates: 2/19/14-2/21/14

Morbidity and Mortality

From a life and health science viewpoint, obtaining accurate information on the top causes of death is very important. The news all too often takes on a ‘pet disease of the month’ and may distort people’s views on how common that condition truly is versus others that are not reported. This lesson is designed to give you an opportunity to use more reliable data to see what diseases and conditions are the most cause for alarm here in the United States and throughout the world. This will allow you to make more informed choices and make recommendations regarding how resources (time, money, etc…) should be distributed in disease research.

Go to my wiki page on Morbidity and Mortality and follow the instructions there to create a report using data from the CDC and WHO.  The report should contain graphs and statistical analysis to support your claims.  Your paper should be in typical APA format and should have a title page, an abstract, a brief introduction, a brief materials and methods section (in paragraph format), results, and an extensive discussion.  The discussion should contain conclusions and insights and not just restatement of the facts I could simply see myself by looking at the data.

Due: Tuesday, February 11, 2014 (at the beginning of class)

Who Decides?

In November of 2013 a young woman, Marlise Munoz, had a blood clot in her lung and collapsed to the kitchen floor.  When she was taken to a Texas hospital she was put on life support but later pronounced brain dead.  Being brain dead is considered synonymous with no longer being alive.  By all medical and legal standards, Marlise was now dead.  But Marlise was also 14 weeks pregnant.  Her husband and parents both wanted Marlise removed from life-support and said it was also Marlise’s wish should such an event ever occur.  The hospital said no, citing a Texas law that states, “A person may not withdraw or withhold life-sustaining treatment under this subchapter from a pregnant patient.”  There are several links below to articles related to this story.  Read them and then decide for yourself if Marlise should have been removed from life support as the husband and family requested or if the hospital did the right thing in an attempt to save the fetus.  You can feel free to use any other sources for information as well.  The point is that you make an informed decision.  Be sure to write professionally and be respectful in your posts and responses – no matter what you opinion is, we are talking about a tragic situation here.

In the end, you should have one original post with your opinion on what should be done in this case and at least one response to someone else’s post.

The Sense of Vision

Neuroscience students should be sure to read Brain Facts chapter 3 (Senses and Perception) and pages 542-563 in your book, which is about the eye and vision.  In particular, by the time you come back from break, make sure you know the parts of the eye, extrinsic muscles of the eye and which motions they control, and the visual pathway from the retina to the occipital lobe via the optic nerve, tract, chiasm, etc…  Be sure to note which visual information crosses hemispheres and which does not as it pertains to the eye’s visual field.

Due: January 2, 2014

Neuroscience CNS Test

Test on Tuesday, 12/17/13, on all information covered this year.  Extra emphasis will be on the information since the last test, including notes about the brain and spinal cord, Dr. Edelsohn’s lectures on various disorders, readings from the text book and the Brain Facts book, and information about cord level sensory, motor and reflex testing.
