Designing Bridges

Lower Elementary Motion & Stability In Classrooms

Students collect data about three bridge structures and engineer their own bridges.

Unit Overview

In Designing Bridges: To Get to the Other Side students use the Engineering Design Process to design a bridge that is strong and stable. They test different bridge types and explore the pushing and pulling forces that act on structures.

  • 5 lessons (8–9 class sessions)

Unit Map

Unit map for Designing Bridges: To Get to the Other Side.

Students explore the concepts of engineering and technology. (30–40 min.)

The class reads a storybook in which a boy named Javier living in Texas explores the field of Civil Engineering in order to build a stronger bridge to his backyard fort. (90–120 min., 2–3 sessions)

Students carry out investigations to observe how forces affect the stability and function of structures. (55–60 min.)

Students create models of three bridge structures and collect data to determine the properties of each. (95–110 min., 2 sessions)

Students follow the steps of the Engineering Design Process to imagine, plan, create, test, and then improve their own bridge designs. (100–120 min., 2 sessions)
