Design, build, and break (safely!) a popsicle-stick truss/arch bridge to explore tension vs. compression, load paths, and failure modes. Teams prototype, test with a hanging bucket, and compare strength-to-weight for engineering optimization. 💪📈 Students will: 🧠 Plan a design that meets criteria & constraints (span, clearance, materials). 🧪 Build & test a truss/arch using craft sticks and glue; add weight gradually until first crack & max load. 📊 Record & analyze mass, first-crack lo
