You will need a sink or large container full of water, a few household objects of different materials and sizes (piece of paper, a key, a small plastic toy, a stick, a nut, a ring etc)
Invite your child to drop in the water one object and observe if it sinks or floats and explain why. Next ask your child to guess if the next object will sink or float, drop it in the water and observe.
Next you can try to make a boat using different materials. First of all paper, then by using a plastic plate as base, a wine bottle lid, a shell etc. Observe some of them sink, and other float.
Here is M. trying sink or float with some rubber toys, a small stone and a boat made with a plastic plate and a sailing.
