Sinking and Floating Facts. Have you ever wondered about why some things sink and some things float? You might even think that bigger things sink and smaller things float, but in the weird and wonderful world we live in, that’s not actually true!

Why Do Things Float in Water? ... Density is a big part of why some things float and others don’t. Objects like coins, rocks, and marbles are more dense than water. They will sink. Objects like ...


Students will make predictions and carry out experiments to test their predictions. Students will identify important properties that may affect an object's ability to sink or float. Students will design specific experiments to determine the effect of changing the mass or volume of an object on that object's ability to float or sink.


heavy objects sink and light objects float regardless of their size, shape or the type of material used to make them; a true floating object must be wholly above the surface of the liquid; all objects that float must contain some trapped air and that is the only reason why they float


Floating or sinking of an object does not depend on its weight, it depends upon its density. Things denser than water sink in water whereas things having less mass than water float over it. In ...


How Things Float Overview. Things float when they are positively buoyant, or less dense than the fluid in which they are sitting. This does not mean that an object has to be lighter than the fluid, as in the case of a boat; objects just need to have a greater ratio of empty space to mass than the fluid.
