About: We started working on the Bridge project after we came back from winter break. I used thin wooden sticks and strong adhesive glue. I probably used 11-15 sticks in all, but I didn't keep track. The design I used was one that I made up by myself. I wanted it to be original. The base was very strong, I had two long sticks (about 38 cm) and shorter ones perpendicular across. These smaller ones (about 5-6 cm) were then glued in between. I also decided to make my bridge curved at the top, and not a straight box. This turned into a problem, and later how it actually broke. There was a web of smaller and larger sticks glued together, but of course this didnt work out, it was too weak. It took a long time to build.

Reflection: The bridge broke in places along the top curve, where the glue didn't hold. It obviously was not a good idea to glue random pieces of the wood together, because then the base had to make up for the weight distribution. The bridge also broke on the base, in a place where there was a hole in between the sticks. I really like hos most of my bridge seemed to hold up well, while I was building it, It seemed very strong.
