Year 3 have started looking at magnetic force. We were pretty confident at predicting which objects would stick to a magnet but we were a little surprised that a 2p coin didn’t. This lead us to wonder whether some metals are not magnetic. We repeated our testing with samples of different metals. Iron and steel were magnetic but others, such as copper, zinc, aluminium and bronze, were not. 

However, it turned out that some 2p coins are magnetic. Looking at the dates on the coins we realised that the coins are now made of a different metal.
