Our first bridge only held 41 pounds, but our group mastered bridge building after this bridge.
Our group thought that the strongest part of this bridge was the base, and we thought that the weakest part of our bridge was the side and the middle.
The reason why this bridge broke was because the stick that was on the left side of our bridge that rested on the table snapped.
Our second bridge held a total of 131 pounds! After seeing other kid's bridges and seeing what designs work and don't work our group decided to go with this design. The new design meant that we would have to forget about our old bridge layout and do a completely different layout. This bridge broke in the middle and had no really weak parts.
