Learning about Bridges

You may think bridges are boring, but I’m going to prove you wrong!

This week our class learnt an awful lot about bridges. Mostly about Beam Bridges. Beam Bridges are the first bridges ever built and some are very simple. Even a broken down log could be a Beam Bridge!

We learnt about ‘wind load’, the forces of wind and ‘live load’, the weight of traffic, people or things that are alive. We also learnt about ‘dead load’, the weight of the bridge itself.

Personally I think learning about bridges is a bit confusing, but BUILDING bridges is awesome! We had so much fun building and testing our own bridges made by card, paper and sellotape. We even attached Box Girders onto the bridges to make them over 10 times stronger than ordinary bridges! We tested the ordinary bridge first. It could only hold the weight of 1 dictionary. When we tested the Box Girder bridge, it held the weight of 12 dictionaries! It was very exciting and kind of challenging to do, but that’s what makes it so fun!
