Civil engineers play an important role in all our lives. They are the ones who design and construct structures that all people use, like bridges, dams and public buildings. They have to consider the materials for their structures, where they are located (with the help of geotechnical engineers, of course!) and how various forces will interact with their structures (like cars crossing it, possible earthquakes, or the overall load on top of it!
Groups are getting further and further in their bridge designs, ready to test how cars can cross over them, if the barge can fit under it, and the number of total weights it can hold before collapsing. Some of our designs are so elaborate, that we now have to consider both the time it takes to design them and the number of materials we used. These are REAL challenges that civil engineers face!
Every time second graders have class, they're one step closer to completing their bridge designs! Some groups have completely finished their first bridge designs and have been able to test them for stability and strength.
Be on the lookout as the bridge designs improve based on the data students collect from each of their tests!
What structures did you see today in Chicago? Were they public buildings? Bridges? Archways?
