No Prep Plans Forensic Science: Reconstructing a Crime Scene

No Prep Plans Forensic Science: Reconstructing a Crime Scene | CSI Team Case Investigation

Bring your Crime Scene Investigation & Evidence unit together with this culminating No Prep Forensic Science lesson for Grades 9–12! Students work as a CSI team to analyze multiple types of evidence, reconstruct the most likely sequence of events, and defend their conclusions using scientific reasoning.
In the CSI Team Case Investigation, students build an evidence-supported theory, then respond to new evidence that challenges their original reconstruction. Teams reconsider their conclusions, revise their theory when necessary, and present a final reconstruction supported by the evidence.
