Year 1 were bridge engineers. We’ve previously tested out the strength of different materials in holding weights. Today, however, they completed an independent experiment testing the strength of different shapes. We tested square, triangular, arch and beam bridges. We measured the gap to make sure it was a fair test each time. Then, we balanced 1g weights until the bridges collapsed – which was super exciting! The arch bridges held the most weight so we think this shape is the strongest. What do you think?
