Week 3 

Forensic Science, continued 

q   Quiz Lab Day:  Conversions, Forensic Science, Microscopes, Safety 

q   Forensic Science Webquest (Do Part 2, 3, & 4)
Part 2:  Answer question 11- print a copy to hand in on lab day.     Part 3:  Go to the Discussion Board ( On learningpoint to complete this section.                                                                                  Part 4: 
RESEARCH more on your expertise and bring notes and links to class Wednesday so we can solve the crime!  IF YOU DON'T KNOW whether you're a Star Fish, Crab, Jelly Fish, or Sea Horse, PLEASE STOP BY at beginning of lunch ASAP.  It's the symbol above your head where you sit.  Very very important!!

q   LearningPoint- Discussion Board:  Be sure you have posted for Week 1, 2, and two different Forums on Week 3.    Reminder:  this is worth homework points.  To get full credit, you must answer the discussion questions as well as respond to at least two other students in the class.   

q Conversions.  Practice conversions by doing these problems.  This information will be on the Quiz Wednesday.  (A hard copy of the conversion info can be found in your red lab book-Page F.  Make sure you look at the front and back of the page, or simply use the link above)

q   Labs:  "Techniques and Tools in Biology" 
In class we started these labs:   Blood Stain Analysis and Microscopes. Make sure you finish answering the Blood Analysis questions #1-3 (use complete sentences).   We also started the lab: Analysis of a Threatening Letter- Use and care of the Microscope.    Don't forget to answer the analysis questions #1-12 using complete sentences.  Both labs are due next Wed. 9-10-08 -lab day.    

The metric system measures temperature using the Celsius scale.  On this scale, water freezes at O^oC and boils at 100^oC.  Each degree is 1/100^th of the scale.  Normal human body temperature is 37 ^oC and comfortable room temperature is about 21^oC.

A homicide detective can tell how long ago a person died by the temperature of the body when found. (They also take into account room temperature and size.)  We will simulate tissue cooling over a period of time (time after death).  After making a graph of tissue temperature versus elapsed time, you will then be able to use your graph to guess the time that other similar tissue “died” (was no longer kept at body temperature).

For this section, use the data below to create an X-Y scatter graph, print it (full page),   Bring The Graph to class on Lab Day.  

Data: (Just highlight all of the data, copy, and paste into an Excel worksheet and use the chart wizard to make an X-Y scatter graph (with trend line--the 2nd choice).  Please come in asap if you need help with this.
