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?
- 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:
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.
This is an introduction to the types of law and the rules of evidence that need to be considered for forensic investigators. It gives good perspective to students about the role of forensic investigators and technicians within the criminal justice community. It describes the criminal justice system in the United States in terms of Civil vs. Criminal, Rules of Evidence, etc.
Different types of evidence and how evidence can be entered into a court proceeding is also discussed in this lecture. It provides a framework for the students to consider as the Forensics course moves forward with collection and testing of different types of evidence. They can see where/how the evidence trail will end.
- Direct vs. Indirect Evidence
- Class vs. Individual Evidence
- Civil vs. Criminal Law
- Rules of Evidence
- The Daubert Approach
This lecture takes approximately 75 minutes depending on how much detail and examples are given. It is good to use near the beginning of a Forensics course in high school or introductory college level setting. I use this as the second lecture of the course, after the What is Forensics? lecture and before the Crime Scene Protocols topic.
An introduction to crime scene personnel and procedures. This is the first lesson in my Crime Scene Protocols unit. It takes students through what happens once a first responder has determined that, yes, we have a crime scene here! Then the CSI team gets called in and the process of documenting the scene and properly collecting any evidence must begin.
In addition to the prezi I give my students the following note guide to fill in as I go through the lecture. You can download the note guide as a PDF below.
Crime Scene Protocols Note Guide – PDF
This lecture takes approximately 45 minutes to 1 hour depending on how much detail and examples are given. There is a 10-minute youtube video embedded in the prezi that details methods for picking up trace evidence from carpet.
This PowerPoint presentation and student note guide handout contains 20 slides introducing Photosynthesis and a 7-page handout for students to fill in during the lecture. I have used it with Freshmen and Sophomore Biology classes. It includes the role of photosynthesis, the conversion of light energy to chemical energy, and producers in our environment. It then describes the overall photosynthesis reaction and the highlights of the light-dependent and light-independent reactions, ending with the Calvin Cycle.
Normally this presentation with class discussion would fill a 90-minute block in my classroom.
