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!
 A group sends a toy car across their bridge! 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! |
