Types of forensic evidence

Today we will be looking at different types of forensic evidence.  We are covering some in class with practicals but there are plenty of other kinds of evidence.

1. How many bullets were fired during this crime? How did police know? - http://www.nibin.gov/press/firearms-forensics-boulder-co.pdf
2. Play the game on http://www.trutv.com/shows/forensic_files/games/hiddenmine/index.html , listing one clue that helped you catch the gold thief:
3. If someone's fingerprints are at a crime scene, does it mean they committed the crime?
4. Watch this video (there's music playing but no talking so don't worry if you don't have sound). Why would the Scientist be wearing gloves? - http://www.youtube.com/watch?v=dOdPirQQh9Q
5. A crime has been committed in this office.  See if you cna spot all the objects that have been moved.  make sure you list them in your book as you go!  - http://forensics.rice.edu/html/comparison.html
6. Match these fingerprints to the samples from the crime scene. http://www.trutv.com/shows/forensic_files/games/fingerprint/index.html 
7. How are the fingerprints on our bodies formed? - http://www.sharecare.com/question/how-fingerprints-formed-in-womb

Forensic observation skills

Today we will be doing some work on Forensic Scientists and thinking about the skills they need to be good at their job.

1. Here is another version of the video we saw this morning. 
   
   Write what you need to do to be able to do to see the Bear:

2. Read the article on this link - http://www.history.com/this-day-in-history/forensic-evidence-solves-a-crime What did the forensic investigators need to look for to convict the killer?

3. Why might it be important for Forensic Scientists to take lots of photos at a crime scene?- http://science.howstuffworks.com/crime-scene-photography.htm

4. What are latent fingerprints and how can they be recorded? - http://www.wisegeek.com/what-are-latent-fingerprints.htm

5. Why is teamwork important for Forensic investigators? Think about the activity we did in class with the skeleton last week: - http://www.askaforensicartist.com/great-teamwork-to-reading-and-west-reading-police-departments/
