Popsicle Stick Truss Bridge Load Challenge (ENG01) | Middle School Civil Engineering (Grades 6-8)

? Popsicle Stick Truss Bridge Load Challenge (ENG01)

Explore structural mechanics, load distribution, tension vs. compression, and geometric efficiency! The Popsicle Stick Truss Bridge Load Challenge (ENG01) challenges middle school student teams to act as civil engineers, designing a lightweight, high-strength truss bridge to span a 30 cm gap and carry maximum load weight.

Students explore tension, compression, structural geometry (triangles vs. rectangles), Warren/Pratt/Howe truss patterns, load transfer vectors, and structural efficiency math!
