AT school we have been working with an engineer to create a model of a bridge with a moving element.
We were given a design brief of building a bridge that was over 1.5m long and 1.2m tall, as well as having a motor to allow the bridge to open and close.
We began by exploring a range of local bridges and decided we wanted to build Tower Bridge. We created a structure using a range of square and triangle shapes, while experimenting with the bracing to ensure the structure was strong and secure.
Next, we experimented with string and the motors to find the best way to allow the bridge to move up and down without it getting tangled. Finally, we used a range of different materials to make it a true model of Tower Bridge.
We loved this project and it’s something we’ll always remember!
