Maddie is exploring why some materials sink when others just stay on the top floating round - what makes things sink or float? She tries lots of different objects and asks - Will it sink or float? We see Maddie at the beach with armbands and a rubber ring, they all float because they are full of air! Maddie tries something heavy, like a big old key, it sinks. We learn if it an object floats, we call it buoyant but if not, it will sink – bye, bye! Maddie encourages the audience to try out themselves what objects might float and sink
