Year 4 look into Roman Engineering

As part of their Romans topic, Year 4 visited the STEAM space this week to discover more about Roman Engineering. They looked at many Roman bridges and found that curves and layers were used to make the bridges strong. They carried out their own investigation to find out if layers were the strongest or if curves were the strongest. Most groups found that curves were stronger, in fact four times as strong as layers! Not all groups agreed though, and we all decided that we would like to test out many more types of bridges in the future.
