Overview of topics, by lesson: 1) bridge types, tension and compression forces; 2) design, loads, piers/columns and girders/beams; 3) geology, foundations, bearing pressure and settlement; 4) strength of materials; and 5) economics, estimates, costs.

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).
