Is it true that heavy things sink and light things float? At first sight this seems to be true but on closer examination it is found to be wrong.If items having the same weight but made of different materials(e.g.wood,stone,wax,copper,steel etc.) are placed in water some will sink while other will float.the 'sinkers' are the same weight as the 'floaters' so what distinguishes them?In this case the sinkers will be found to be the physically smaller items-that is,smaller in volumes.so we could say that the sinkers are heavier for their size than the floaters.
