Year 1 and 2 have been set a special challenge this week! Using our knowledge of Tower Bridge, we needed to make different shaped towers to see which was the strongest. We made a cylinder, cuboid and triangular prism shape and tested their strength using books. It was a little tricky to make some of the shapes but we worked well collaboratively and had lots of fun! We were very surprised to see how many books the cylinder shaped towers could hold before they collapsed!
