Paper Bridge Timeline

This Timeline shows a 9th-grade science teacher, Nancy Cianchetta, from Everett, Massachusetts, doing the paper bridge challenge over the course of three days. Everett is an older industrial town in New England that has seen its manufacturing base close, and is a suburb of Boston.

Day 1 of the Timeline shows Nancy introducing students to the notion of a bridge carrying a single water bottle as a load, and the need in engineering to make the bridge with as little material as possible while still supporting the load.
In Day 2, the design teams take on the challenge of supporting 3 water bottles with as light a bridge as possible.
In Day 3, Nancy conducts a teaching lesson/discussion as a review of key ideas before students design and make their final designs.
