Forensics: DNA Evidence

This is my DNA Evidence lecture given in a forensics class about types of evidence that contain DNA.  It also describes Polymerase Chain Reaction (PCR) and DNA Fingerprinting by electrophoresis in detail.  There is also an embedded youtube video in the prezi and the powerpoint.  The content in the prezi and powerpoint are identical so it is just a matter of choice for the teacher.  Do you want to use the free prezi or purchase the powerpoint from my TPT store?

Topics include:

  • DNA Structure
  • Polymerase Chain Reaction
  • Gel Electrophoresis
  • DNA Fingerprinting
  • Types of DNA Evidence

The prezi above is available for free and there is a student note-guide available in my TPT store, plus a powerpoint version of the prezi if you prefer that format:

In Practice…

This lecture takes approximately 75 minutes depending on how much detail and examples are given.  It is good to use in a Forensics course in high school or introductory college level setting.  It includes a refresher section but most students  have had some introductory biology so they have been exposed to DNA structure and replication.

Forensics: Virtual Autopsy Activity

forensics: virtual autopsy activityThis is a great virtual autopsy activity for a Forensics course or unit on pathology or anatomy.  Students visit a website that has 18 different examples of autopsies with lab results for each body system.  Students record all relevant information and then try to determine the cause of death.  This can be used as an introduction to the unit, as an activity within the unit, or even as a great sub plan!  Best part, we don’t have to view a real autopsy!
Here is the link to the website used in the activity: http://www.le.ac.uk/pathology/teach/va/titlpag1.html
The following handouts are available from my store for a very low price.  Click here to get the handouts.

My students love this project, even seniors who are nearing the end of their high school days!  Each file is included as both a PDF and Word document so you can customize as needed.  Please comment your questions, suggestions, or successes!
