Script for pencast on forensic science

This is the pencast for the Forensic science presentation, Hour 7, narrated by Rebekah and written by Makaylah. We will be introducing the main ideas and some unique facts about fingerprinting, blood types, and some different forensic careers. The first part will be fingerprints. the most important thing you should know about finger prints is that **//__they are all unique__//**. **//__No one__//** **//__has the same two fingerprints__//**, **//__every one is different.__//** There are about 6-7 main fingerprint patterns. They are the whorl, the loop, the pocket, the arch, the double loop, the tent arch, and mixed. Although there are only 6 main kinds, they can curve and twist and stretch to make billions of different patterns. There are also parts that go into all of these, or certain designs, like deltas, which are like small triangles. There are also ridges, and they are small bumps. Then there are loops. These are just what they sound like, a large swirl. (draw deltas, loops, and ridges).

Now on to the second part of the pencast, Blood! There are **__//four//__** blood types**//__,__// //__A,B,O, and AB.__//** All four can be **//__positive (+)__//** or **//__negative (-__////__),__//** depending on the antigens attached to the cell. We will explain this in our main presentation. there are two kinds of blood that are very unique, they are O-, and AB+. O- is the "universal donor", meaning that anyone can have it transfused into them in a medical emergency. AB+ can receive any kind of blood. It is the "universal receiver". This means that anyone with this type of blood can accept any other type for transfusion purposes. If you ever require a blood transfusion, it is essential that you know what kind of blood you have so that the doctors can put more of it into you. Usually a child will have the same blood type as one or both of their parents, it is rare if they don't.

The last part of this pencast doesn't require any writing. There is a wide variety of forensic careers, but some of the more common ones are Forensic Toxicology, Forensic firearms examiners, and Forensic photography. Forensic toxicologists study the affects of drugs on people (ususally who were involved in a crime) and there bodies. Forensic firearms examiners are trained to identify and locate firearms at the scene of the crime, usually guns. Finally, Forensic Photographers capture images of crime scenes to collect evidence. That is the end of our pencast, we hope you enjoy our presentation!
