2 Students Building Mobile Sculpture DesignsDesigns

Three NYC locations need new bridges — and a city engineering firm has called on your students to design them. Working in teams, they investigate the four main bridge types, see how compression and tension shape every structure, and run hands-on tests that reveal how design choices affect strength and span. Each team is assigned a real location with real constraints: the bridge has to hold weight, allow passage underneath, and fit the site's specific needs. Students leave thinking like civil engineers — with evidence-backed designs they can defend.

What Students Learn

  • The strengths and weaknesses of the BATS Bridges: Beam, Arch, Truss, and Suspension

  • How compression and tension act on different parts of a bridge and why structure determines function

  • How engineers evaluate design trade-offs against real location constraints

  • How scientists and engineers ask questions, gather evidence, and defend their thinking through all 8 Science and Engineering Practices

What's Included

  • 10 slide-based lessons with embedded graphics and media

  • Step-by-step teacher guide with facilitation notes

  • Student worksheet packet with pre/post assessment

  • All hands-on building materials

  • Maker skill video tutorials
