Tacoma Narrows Bridge STEM Case Study Packet

Investigate one of the most famous structural engineering failures in history with this comprehensive, no-prep 6-page printable STEM Case Study Packet! Designed specifically for middle and high school classrooms, this multi-day unit gives students an immersive, highly informative look at the iconic 1940 Tacoma Narrows Bridge Collapse. By combining real-world physics, forensic investigation, mathematical modeling, and professional ethics, this resource transforms a historical disaster into a rich, interactive learning experience.

Throughout this unit, students explore complex STEM concepts—including mechanical resonance, aerodynamic flutter, wind shear forces, structural rigidity, and engineering design ethics—in an approachable, highly engaging format.

What’s Included in this 6-Page Deep-Dive Packet:

• Page 1: Historical Case Study & Technical Breakdown

  Features a full historical narrative of "Galloping Gertie," detailing its initial construction, structural dimensions, and unique physical profile. Students learn about the physics behind aerodynamic flutter and mechanical resonance while answering critical comprehension check questions that reinforce key technical vocabulary and core concepts.

• Page 2: Day in the Life Scenario Challenge

  Students step into the shoes of a Lead Forensic Structural Engineer on the morning of November 7, 1940. In this immersive roleplay assignment, they analyze real-time wind speeds, torsional twisting angles, and cable tension diagnostics to identify key warning signs and understand why the bridge ultimately failed.

• Page 3: Hands-On Unplugged Simulation & Applied Math

  Brings theory into practice with step-by-step math calculations. Students work through simple, applied equations comparing wind pressure forces, bridge deck flexibility ratios, and natural frequency oscillation cycles to quantify the physical limits of structural design.

• Page 4: Engineering Ethics & Workplace Dilemma

  Explores the real-world pressures faced during construction projects. Students evaluate the trade-offs between cost-saving lightweight girder choices and public safety, analyzing the impact of budget cuts, aesthetic design preferences, and overlooked structural code warnings.

• Page 5: Redesign Brief & Innovation Lab

  A creative blueprinting assignment where students act as modern engineers designing "Tacoma Replacement-V2." Applying what they have learned, they incorporate open-web steel trusses, aerodynamic wind vents, and diagonal stay-cables to engineer a safer, rigid structure.

• Page 6: Teacher Answer Key & Scoring Rubric

  Includes complete, step-by-step solutions for all narrative comprehension questions and mathematical calculations, alongside a clear 10-point grading rubric to streamline assessment for the design blueprint assignment.
