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

Learners build a model of a suspension bridge and test the amount of weight it will support. In this engineering lesson, students study types of bridges and attempt to construct a suspension bridge shown in a diagram. They use string and...

Students demonstrate the three states of matter. In this matter lesson, students read Bartholomew and the Ooblek. Students create "ooblek" and discuss what state of matter it is.

Learners classify different mixtures. In this mixtures lesson plan, students determine samples to be suspensions, colloids, or solutions and compare homogeneous and heterogeneous mixtures.

Students study bridges and design and build their own. They explore different types of bridges and build a basic beam bridge in pairs. After creating their beam bridge, they design a truss bridge and then build a suspension bridge and...

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.
