Investigate the 1940 Tacoma Narrows Bridge collapse with this 6-page STEM packet covering resonance, structural engineering design, ethics, and physics.
Engage your middle and high school students with a comprehensive, hands-on deep dive into one of history’s most famous structural engineering disasters. This complete printable unit bridges history, physics, and practical design challenges to teach mechanical resonance, aerodynamic flutter, wind shear forces, structural rigidity, and engineering ethics.
What’s Included in this 6-Page Unit Packet:
Page 1: Historical Case Study & Technical Breakdown – Full narrative of “Galloping Gertie,” structural dimensions, aerodynamic flutter physics, resonance concepts, and comprehension check questions.
Page 2: Day in the Life Scenario Challenge – Roleplay assignment where students step into the shoes of a Lead Forensic Structural Engineer on November 7, 1940, analyzing real-time wind speeds, torsional twisting angles, and cable tension diagnostics.
Page 3: Hands-On Unplugged Simulation & Applied Math – Step-by-step math calculations comparing wind pressure force, bridge deck flexibility ratios, and natural frequency oscillation cycles.
Page 4: Engineering Ethics & Workplace Dilemma – Critical thinking exercise exploring cost-saving lightweight girder choices versus public safety, budget cuts, aesthetic design pressures, and structural code warnings.
Page 5: Redesign Brief & Innovation Lab – Creative blueprinting assignment where students design “Tacoma Replacement-V2,” incorporating open-web steel trusses, aerodynamic wind vents, and diagonal stay-cables.
Page 6: Teacher Answer Key & Scoring Rubric – Complete solutions for all analytical questions and math calculations, along with a 10-point grading rubric for the design blueprint.
