Toothpick Bridge STEM Challenge ENG04

Civil Structural Engineering STEM Bundle

Middle School Civil & Structural Engineering Bundle: 5 complete lab packets (15 pages total) connecting bridges, towers, domes, & roller coasters. Transform your middle school science classroom into an active engineering firm with the complete Civil & Structural Engineering STEM Lab Bundle (ENG01–ENG05)! Designed specifically for Grades 6–8, this comprehensive 15-page bundle delivers 5 hands-on, high-impact engineering challenges that bridge structural physics, material science, forces and motion, and applied math. Students explore truss geometry, high-rise column mechanics, geodesic dome compression networks, micro-truss joint gussets, and potential-to-kinetic energy coaster physics through engaging destruction and motion testing competitions! Each lab follows our signature clean 3-page packet format: Page 1 Teacher Guide, Page 2 Student Mission Blueprint Workspace, and Page 3 Testing Log & Scientific Reflection. 📦 What Is Included in This 5-Lab Bundle (15 Pages Total)? ENG01: Popsicle Stick Truss Bridge Load Challenge — Truss geometry, Warren/Pratt/Howe patterns, tension vs. compression, and mass-held efficiency ratios. ENG02: Newspaper Skyscraper Tower STEM Challenge — High-density beam rolling, center of mass alignment, triangular bracing, and lateral wind shear resistance. ENG03: Geodesic Dome Compression Load STEM Challenge — 2V geodesic networks, triangular tessellations, multidirectional compression dispersion, and nodal failure analysis. ENG04: Toothpick Bridge Truss Load Challenge — Micro-structural mechanics, wood grain compression, joint gusset plate mechanics, and shear failure testing. ENG05: Paper Roller Coaster Momentum & Energy STEM Lab — Gravitational potential energy to kinetic energy conversion, 360-degree loop centripetal force, friction loss, and velocity math. 📐 Core STEM Concepts & Applied Math Covered: Tension, Compression, Shear, and Torsional Force Vectors Triangular Rigidity vs. Polygonal Structural Deformation Gravitational Potential Energy & Kinetic Energy Transformations Centripetal Acceleration, Wind Shear Deflection, and Friction Losses Data Logging, Ratio Math (Structural Efficiency), and Average Velocity Calculations 💡 Why Teachers Love This Bundle: Plug-and-Play Uniformity: Every packet features a standard, clean layout that students can navigate independently, freeing you to facilitate testing stations! Low-Cost Materials: Built entirely around everyday budget-friendly supplies (popsicle sticks, newspaper, straws, toothpicks, cardstock, tape, and testing weights). Print-Ready: Zip file containing 5 high-resolution, print-ready PDF files (15 Total Pages).
