Last Wednesday, we did our Arch Construction during our lesson. We were seperated into 4 persons per group and build our own arch bridge. The material used was plasticines.
We shaped the plasticine into a cylindrical-like shape to be supported to the abutments of the arch.
We also cut the plasticines into rectangular shape, to build the brick-like columns.
This is how our arch bridge looks like, after decorated and being built.
These are all arch bridges from all groups. They were readied to be tested their stability.
Our groups' arch bridge was one of the top three strongest arch bridge.
From the activity, we learnt about how to construct a strong bridge, and determine the construction ways to make it harder and stronger. We had a lot of fun during the activity, and learnt to cooperate with every group members.
