In year 6, as part of our learning about the Titanic, we looked at how objects float. Obviously we knew that some materials were better at floating, but what about metal? Ships are made of metal, the Titanic was iron! 52,310 tonnes of it!
We started with a ball of plasticine, which sank, and then investigated the different shapes we could mould it into to help it float. Once we worked out the best shapes which floated, we looked at how many marbles our designs could hold.
