Building Bridges

How high can you go? In a STEM design challenge, teams design and build a structure using only dowel rods and rubber bands. The goal is to build the tallest freestanding structure using all of the dowel rods. Teams present their designs...

Using popsicle sticks and glue, groups must work together to design and build a bridge that can support weight and is aesthetically pleasing. The lesson begins by learners reading about different features of bridge architecture, followed...

Engage young scientists in a project where high fashion meets engineering! Using foam core and hot glue, partnered pupils design and create a functional, fashionable pair of shoes. Groups then put the footwear through its paces using a...

What kind of design challenges are there in building structures to support rocket engines? The unit takes design teams through the process of building the lightest possible thrust support structure that can withstand the necessary forces...

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...

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 reaction of...

Introduces your class to the types of loads experienced by a bridge. Groups calculate the ultimate load combinations to determine the maximum load requirement. Using this information, builders then determine the amount of material they...

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...

Class members use mathematics in order to better understand magnetic forces and their interaction on charged particles. After a demonstration of the interaction between a magnet and an electron beam using a CRT computer monitor, learners...
