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...

Build a bridge to bridge the connection between the abstract and the concrete. The seventh installment of an 11-part unit on architecture has teams build a bridge out of Popsicle sticks that spans the greatest distance while supporting a...

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 activity to record their observations of the reaction of...

Spanning across time—well, maybe not time. Using simple materials, teams design, draw, and then construct a bridge. Teams build the strongest, safest, and most economical bridge using the materials from the supply price list. Each team...

Students 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.

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...
