Poison Activity
We had to cover 3 things. The first being What is the definition of a poison:. A poison is a substance that, when introduced into the body causes death or injury. The second being What are Examples of poison?An example would be the metal lead , sugar and and pesticides. If a person is allergic to something that automatically becomes a poison is like sugar to a diabetic Than third What are symptoms of one that has been infected by poison? Symptoms of poison can be enlarged pupils, foaming of the mouth and nausea. In this lab we had to test certain substances for aspirin, iodine, sugar, cyanide etc. Poison can be concealed in drinks or foods so it may be hard to see the cause of death at first look.

Ex 10- A single Plain whorl loop fingerprint.
Ex 11- A lifted finger print a left thumb.it was an Ulnar loop.
* In Monk's voice* Here’s what happened....
Sooooo... This all took place in a Bar/ Strip Club. It was late night and only Candi and Ginger was there. They had to resolve some unfinished business concerning money so Candi could pay for her drugs. Ginger fixed a blue cocktail and gave it to Candi. Ginger was in debt to Candi and to pay it back to her she gave Candi the chain. Candi became enraged because she saw it was not real gold. She leaped at Ginger and they begin to brawl. That explains the black fiber found it was from one of their clothing. Earlier that day Ginger has left a note behind the bar because she knew that later that day something bad might happen. Candi slit her throat with some unknown object and as she fled, a note from her pocket fell out.

Witness Experiment
In our class we were given a sheet that held instructions to this activity. The first thing was to work in threes and cut out 3 pictures of the same sized faces in a magazine. Cut out all the important facial features and memorize the face you have picked, cut out, and ensemble. Mix up the 3 faces together than use at least time as possible and remembering the facial features re-ensemble your face from memory. This was a good experiment and excersice because if we witness a crime on the street one day, many days after the fact we will still be able to accurately report specific details.
Create a Profile
In our class at our tables we were handed 5 envelopes. All of them were clues to a crime, the envelopes included Hair/ fiber, lipstick, a torn up letter, and fingerprints.
Clue 1
4 fingerprints= 3 ulnar loops and 1 plain whorl
Prints were from the left hand.
Clue 2
Hair sample that was a long thin strand of possibly dyed,caucasion hair.
Clue 3
A torn up letter reading " You will never find her " in cursive.
So from this we know that the victim is a female and she is missing.
Clue 4
Hair sample that was short and thick and dark. Could be Asain hair or synthetic hair.
Clue 5
A stain that was not easy to tell what it was by just looking at it. It was pink in color,couldve been lipstick, blood, or a red drink.
We know that 2 people were involved and that a female is missing. We need to further find out who it was and why.

Drug Analysis
In this lab we had 3 replicas/simulated drugs. *Meth, Cocaine and LSD. We worked in groups of four, first we took the "drug" and mixed it with water than put it in a petri dish. After that we tested the substances for their pH and their specific "drug" indicator.
"Cocaine"
*Meth was not able to be tested
Drug # | Color and pH | Cocaine | LSD |
1 | Orange and Yellowish pH6 | - | - |
2 | Blue pH10 | + | - |
3 | Orange pH3 | - | + |
4 | Green and Yellowish pH7 | + | - |
5 | Yellow pH7 | - | - |
6 | Orange pH3 | - | + |
"Cocaine"
*Meth was not able to be tested
Lipstick
In my class we were given little squares of sheets of paper. We had a choice of alot of lipsticks. We applied a lipstick to our lips and kissed the white sheet of paper. We than analyzed our lip prints to point out any obvious and distinguished marks, than we observed and recorded .

Footprint
In our class we had dirt collected outside. We recorded the temperature and weather conditions and when it last rained. We worked in groups of 3 and one person went at a time. Coincidentally, everyone in my group has converse all-stars so we did not have to analyze the difference between the various brands. We determined from the footprint any distinguishing features, the brand, the length and width, the direction (north, south etc.) and the individual characters. We than came up to a conclusion on how female and male is different.
