FREE Middle School Seismic Engineering Lab: 3-page STEM packet on seismic waves, cross-bracing geometry, center of gravity, & base stability math.
Bring plate tectonics, structural seismology, and physical science to life with this 100% FREE 3-Page STEM Activity! The Earthquake Resistant Tower Challenge (ESS01) channels your middle school students’ energy into hands-on physical science concepts like seismic wave dissipation (P, S, and Surface waves), structural shear strength, cross-bracing geometry (triangles), and center of gravity balance!
Students explore seismic wave mechanics, structural shear resistance, cross-bracing triangular rigidity, center of mass alignment, and base stability ratio calculations!
What Is Included in This 3-Page Packet?
Page 1: Teacher Guide & Lesson Plan: NGSS alignment (MS-PS2-1, MS-ETS1-2), target science concepts, shake table testing parameters, setup notes, answer key, and expected student outcomes.
Page 2: Student Mission Card & Blueprint: Real-world civil and seismic engineering scenario hook, clear material limits box (straws, pipe cleaners/tape, cup, penny weight payload, 30 cm height rule), and a dedicated Seismic Structural Integrity Blueprint sketching zone.
Page 3: Testing Log & Scientific Reflection: Structured Data Testing Table (track structural modifications, shake table testing outcomes across slow vs. fast shaking, and failure mode analysis), Applied Math Connection (calculate Base Stability Ratios = Base Width / Total Height), and physics reflection questions.
