Lesson 2: Securing the Scene: Collecting Evidence Copy

Wrongdoers, beware! Learners visit the scene of the crime and use real forensic techniques (such as triangulation) to begin the search for trace evidence that will point to a thief!

Use special care to keep learners out of the “crime scene” area and use the opportunity to underline how careless investigators can contaminate crime scenes. Encourage students to move methodically through the crime scene as they measure; in this lesson make the distinction between evidence and suspicions.

Lesson Objectives
