Students demonstrate tension and compression using real world examples. In this forces lesson, students demonstrate tension on a suspension bridge. They demonstrate compression on different roof designs.

Learners design a bridge. In this science lesson, students research different types of bridges and create a bridge using marshmallows, toothpicks and construction paper.

Survey potential bridge sites, research bridge design, and select the right bridge for the right location in this interactive activity from the NOVA: "Super Bridge" Web site.

This interactive activity, from the Web site developed for the PBS series "Building Big," use your knowledge of bridge design to match the right bridge location in a fictitious city.

Students incorporate their knowledge of civil engineering and physics principles as they design and build a bridge within certain parameters while choosing their own materials.
