Learning from the past, for the future.

Roman aqueduct in Nimes, France

Although the Romans didn’t invent the arch, they did develop it. They were the first people to use it in large buildings and concrete in their constructions. In Year 3, we wanted to find out more about engineering and bridge construction.

First, we constructed a simple ‘beam’ style bridge using books, thin card and weights. Very quickly we discovered how easily they collapsed! Next, we used a second card to form an arch underneath. This worked much better. We discussed why this might be so. Perhaps a Year 3 engineer could answer this?

To investigate further, we wanted to know which type of arch bridge would be stronger… a tall, narrow arch? A wide low arch? Or an arch of medium height and width?

Can you predict what our results were?
