Explosives & Post-Blast Investigation

Transform your forensic science, chemistry, or criminal justice class into a real-world investigative unit with this comprehensive lesson on Explosives and Post-Blast Investigation!

This is not just a worksheet; it’s a complete, no-prep academic module designed to challenge and engage high school and university-level students. Guide them through the complex physics, chemistry, and meticulous procedures that forensic experts use to solve one of the most chaotic types of crime scenes.

This all-in-one digital resource is meticulously structured into three phases, moving students from core theory to practical synthesis and analysis.

WHAT’S INCLUDED (39-PAGE PDF):

Phase 1: Core Content & Theory (Academic Guide): A 10-page university-level text that serves as the foundation for the entire unit. It covers:
Explosive Classifications: The difference between deflagration and detonation, low vs. high explosives, and the sensitivity tiers (Primary, Secondary, Tertiary).
Blast Scene Reconstruction: The physics of blast waves, locating the seat of the blast, and fragmentation vector mapping.
Residue Analysis: The science of post-blast swabbing, collection protocols, and advanced laboratory techniques like GC-MS and Ion Chromatography.
IED Anatomy: Deconstructing improvised explosive devices using the PIES methodology (Power, Initiator, Explosive, Switch) and signature analysis.
Phase 2: Student Workbook (10 Rigorous Worksheets): A series of 10 scaffolded worksheets that test comprehension and critical thinking. Topics include:
Fundamentals of Explosive Classifications
Velocity of Detonation (VOD)
Anatomy of an IED
Switch & Fuzing Mechanisms
Blast Physics & Wave Dynamics
Scene Reconstruction
Fragmentation & Vector Analysis
Residue Collection Protocols
Analytical Chemistry
Comprehensive Case Study: A final worksheet that ties all concepts together, challenging students to analyze a realistic bank bombing scenario.
Phase 3: Visuals & Teacher Resources:
High-Resolution Diagrams: Three clear, professional diagrams covering Explosive Classification, Investigation Workflow, and IED Anatomy—perfect for presentations or as student handouts.
Comprehensive Answer Key: A complete, detailed answer key for all 10 worksheets, including the case study, to facilitate easy grading and in-depth class discussions.
Perfect for:

University/College Forensic Science or Criminal Justice Programs
Advanced High School Forensic Science (11th-12th Grade)
AP/IB Chemistry or Physics (as an application-based unit)
Career and Technical Education (CTE) Law & Public Safety pathways
Homeschool curriculum for advanced STEM students
