SummaryThrough a five-lesson series that includes numerous hands-on activities, students are introduced to the importance and pervasiveness of bridges for connecting people to resources, places and other people, with references to many historical and current-day examples. In learning about bridge types—arch, beam, truss and suspension—students explore the effect of tensile and compressive forces. Students investigate the calculations that go into designing bridges; they learn about loads and cross-sectional areas by designing and testing the strength of model piers. Geology and soils are explored as they discover the importance of foundations, bearing pressure and settlement considerations in the creation of dependable bridges and structures. Students learn about brittle and ductile material properties. Students also learn about the many cost factors that comprise the economic considerations of bridge building. Bridges are unique challenges that take advantage of the creative nature of engineering.
Engineers are involved in many aspects of weather forecasting and weather-appropriate design. They analyze information about weather when designing instruments such as barometers, thermometers and anemometers—technologies that are essential for accurate weather predictions so that we can make informed decisions about how we interact with our world. Also, computer science engineers develop software to integrate these complex weather information technologies for meteorologists to use to make such predictions and inform the public. Engineers develop websites (and software) to present predicted and historical weather information in the most informative and pleasing way for people to understand. Civil engineers utilize weather data when designing bridges, houses and other structures, to ensure that those designs are appropriate for the climate of their locations. Environmental engineers analyze weather measurements to determine the placement and effectiveness of renewable energy technologies, such as wind farms and solar arrays. Engineers also serve an important role in designing products that enable people to more comfortably adjust to the weather (for example, waterproof jackets, heated driveways and sunscreen, and many other weather-resistant goods).

Students are presented with a brief history of bridges as they learn about the three main bridge types: beam, arch and suspension. They are introduced to two natural forces — tension and compression — common to all bridges and structures.
Students learn about the types of possible loads, how to calculate ultimate load combinations, and investigate the different sizes for the beams (girders) and columns (piers) of simple bridge design. Additionally, they learn the steps that engineers use to design bridges.
Each TeachEngineering lesson or activity is correlated to one or more K-12 science,
technology, engineering or math (STEM) educational standards.
All 100,000+ K-12 STEM standards covered in TeachEngineering are collected, maintained and packaged by the Achievement Standards Network (ASN),
a project of D2L (www.achievementstandards.org).
In the ASN, standards are hierarchically structured: first by source; e.g., by state; within source by type; e.g., science or mathematics;
within type by subtype, then by grade, etc.
