Young scholars research three major bridge collapses. In this Physical Science lesson plan, students will sketch a bridge design for their area after their research. All bridge designs will be presented to the class to discuss strengths...

Students, in groups, design and test a scale bridge. They use the Internet to research three basic bridge designs -- beam, arch, and suspension -- and the forces that act upon them.

Eighth graders build a structure that is able to withstand a simulated earthquake. They research earthquakes, earthquake measurement, and society's preparation for and reaction to them. Pupils build models and present them to the...
