For their Take One Picture project, the children in Year 5 chose to focus on the Brooklyn Bridge in the background of the painting. Having considered the forces involved in different bridge designs, we looked at the pros and cons of using paper tubes to build model bridges. The students found that the tubes were very strong end to end but, even if light pressure was applied to the side, they became very weak.
Each class split into teams and had to quickly design and build their bridge before the structures were tested to destruction! Amazingly, three of the bridges held in excess of 20kg and these will be on display in the exhibition next week.
