Unit 3: Sampoong Department Store Collapse (1995) | STEM Engineering Disaster

Product Description: Investigate the deadliest non-deliberate building collapse in modern history with this complete 6-page printable STEM Case Study Packet! Designed specifically for middle and high school classrooms, this unit provides a deep, informative look at the 1995 Sampoong Department Store Collapse in Seoul, South Korea, flat-slab punching shear physics, reinforced concrete column rebar degradation, rooftop AC unit drag loads, structural safety factors, and construction corruption ethics. What’s Included in this 6-Page Deep-Dive Packet: Page 1: Historical Case Study & Technical Breakdown – Full historical narrative of the June 29, 1995 disaster, conversion from office to department store, flat-slab construction physics, punching shear stress, rooftop air conditioning drag damage, and comprehension check questions. Page 2: Day in the Life Scenario Challenge – Students step into the shoes of a Lead Forensic Structural Engineer on June 29, 1995, analyzing real-time building telemetry, column cracking diagnostics, and emergency evacuation protocols. Page 3: Hands-On Unplugged Simulation & Applied Math – Simple step-by-step math calculations comparing column shear perimeter area, punching shear stress thresholds (PSI), rooftop heavy equipment load distribution, and concrete safety factors. Page 4: Engineering Ethics & Workplace Dilemma – Corporate greed vs. structural integrity: analyzing illegal floor additions, removing structural support columns for escalators, ignoring visible ceiling cracks hours before collapse, and building inspector corruption. Page 5: Redesign Brief & Innovation Lab – Creative blueprinting assignment where students design "Sampoong Plaza V-2," featuring drop panels, column capitals, shear wall cores, and real-time structural health monitoring sensors. Page 6: Teacher Answer Key & Scoring Rubric – Complete answer key for all questions and math problems, plus a 10-point grading rubric on Page 6 for evaluating student work on Page 5. Teacher Benefits: 100% Unplugged & Copy-Paste Friendly – Clean text layout with zero dark background boxes, code block syntax, or special math symbols for seamless editing in Word, Google Docs, or Canva. Multi-Day Classroom Value – Covers 3 to 5 full class periods; perfect for Physics, Physical Science, Civil Engineering, Architecture, CTE electives, or emergency sub plans. Highly Engaging Content – Combines structural shear math, forensic building inspection, corporate ethics, and architectural redesign!
