Testing to destruction 2

Earlier in the week we did some work to find out how much weight a single piece of paper could hold and what it took to make things collapse. Today we have tried to find out what the best 3-d shape is to support a weight. We started off by watching a video clip of the collapse of the Tacoma bridge in America.

With out Talking Partners we decided how we were going to build the shapes we wanted to hold our card bridge. The first thing we needed to agree was what 3-d shape we were going to put our structure on. Some of us chose to make cylinders; some made cuboids; some made cubes; some even had a go at making a triangular prism. 

Once we had made our shape we then had to balance a piece of card on it and see how much weight we could add before it collapsed. You can see how much fun we had and how we got on........
