Introduction
Have you ever donated blood or received a blood transfusion? When transferring blood from one person to another, the blood types of both donor and recipient must be considered.
In this lesson, you will learn how blood types are determined and test the blood types of three suspects to look for a match to blood found at the scene of a burglary.
Following successful completion of this lesson, students will be able to...
- List the components of blood and describe each one's function.
- Use blood typing to narrow a list of possible suspects.
Essential Questions
- How can the type of blood left behind at a crime scene be determined?
- How can blood type be used to narrow down a list of potential suspects?
Enduring Understandings
- The principles of scientific inquiry and inductive reasoning are required in all crime scene and forensic science analysis.
The above objectives correspond with the Alabama Course of Study: Forensic Science and Crime Scene Investigation standards: 16.
