Forensic Entomology Case Files PMI Lab (ADD Calculations) Print & Go 9-12
This is the forensic unit students always remember—because the “evidence” is alive (and the math actually matters). In Forensic Entomology Case Files, students work as forensic entomologists using insect development and Accumulated Degree Days (ADD) to estimate postmortem interval (PMI) and test suspect alibis. Every case is built around authentic reasoning: temperature → metabolism → development stage → timeline. This pack is print-and-go (no materials, no prep) and perfect for Forensic
