Fall STEM Activity: Spiderweb Structural Bridge Challenge (FALL02) | Physics

🕷️ Fall STEM Activity: Spiderweb Structural Bridge Challenge (FALL02) Combine Halloween excitement with bio-inspired structural engineering! The Spiderweb Structural Bridge Challenge (FALL02) challenges middle school student teams to act as civil engineers, designing a tensile web bridge out of string, craft sticks, and paper to span a 30 cm canyon gap and hold maximum payload weight. Students explore biomimicry, tensile force distribution, network geometry, structural load efficiency ratios, and load testing! 📦 What is Included in This 3-Page Packet: Page 1: Teacher Guide & Lesson Plan: NGSS alignment (MS-PS2-2, MS-ETS1-2), target science concepts, and material setup guide. Expected student outcomes, answer keys, and math troubleshooting tips. Perfect for your TGM Product Preview! Page 2: Student Mission Card & Blueprint: Real-world biomimetic structural engineering scenario hook. Clear material limits box (yarn/string, straws/sticks, tape, 20 cm span rule). Dedicated Spiderweb Tension Network Schematic sketching zone. Page 3: Testing Log & Scientific Reflection: Structured Data Testing Table: Track web dry mass (g), radial anchor line count, and max load supported (g) across 3 trials. Applied Math Connection: Calculate Structural Efficiency Ratios (Load Mass Supported / Web Mass).
