Suspension Bridge Construction

Your young learners will discover how muscular strength and endurance can increase with this truly hands-on activity! Beginning by writing an acrostic for the word strength, class members then engage in tracking their ability to squeeze...

Here you'll find a great sampling of practice standardized test questions organized into four sections: ELA, mathematics, social studies, and science. Help your learners become familiar with the types of multiple-choice questions...

Cost overruns are unacceptable—in the real world and in an engaging activity. Groups of pupils get together to build a bridge out of straws, paper cups, and tape. They keep track of costs ($1,000 for each material) and must stay within a...

Pupils examine a stress-strain diagram that compares the advantages and disadvantages of the two common bridge building materials, concrete and steel. The also consider the factors that influence the materials builders choose for their...

The London Bridge should not have fallen down. And here's why. After a brief history of bridges and the three main types, class members are introduce to the concepts of tension and compression, the two main forces acting upon bridges. 

Bridges rely on tension and compression to keep them standing. Pairs test this principle by constructing simple bridges and applying a force to the center. Teams use the provided worksheet to record their observations of the...

Learners apply abstract concepts, such as stress, fulcrums, the law of gravity, and the strength of different geometric shapes. Groups of student contractors operate simulated architectural firms to create strong, economical bridges.

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.

In this video segment adapted from ZOOM, the cast tries to design and build a bridge made out of drinking straws that will support the weight of 200 pennies. [4:02]

Pairs work as engineering teams to design and build model bridges from drinking straws and tape. In this third segment in a series of 10, teams compete in an attempt to build the strongest bridge. To help with the design, the groups...
