Why Objects Float

Every object is made out of molecules, if these are spread apart the object is less dense and it will float. Changing the size, material or shape of an object may make a difference as to whether if floats or sinks.

Testing If Something Floats or Sinks

You can test if an object will float or sink by putting it into some water, if it stays on top if floats, otherwise if it falls to the bottom it sinks. This is called an experiment.
