We continued our work on structures today looking at beam bridges and truss bridges. We noticed that truss bridges use triangles. We made our own triangles using straws and masking tape and tested their strength. We discovered that the sides bend if we apply pressure, but not the point.
Our next task was to build a stable, strong bridge using straws and masking tape. We worked really well in teams of three and made some excellent bridges.
We started adding triangles to our bridges for strength. We also spotted some triangles within the roof structure of our classroom!
