How is a scientific law different from a scientific theory

A  

scientific law

describes the behavior of something that occurs. It is often described in mathematical relationships. For example the general law of gravitation describes the force between objects of various masses at various distances  

A  scientific theory

, however, attempts to describe why something works. There are several theories of gravity, which attempt to explain why it occurs as it does.  

Both Scientific Theories and Laws are based upon observation and experimentation. They can be disproved or modified to accommodate new discoveries, and must make predictions about future experiments and observations.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
