Theory Notes:

A theory is a plausible or scientifically acceptable general principle or body of principles offered to explain phenomena, for example the wave theory of light. It is a generally accepted set of rules or body of principles that has been supported by scientific evidence and experimental procedures. An example of this is the theory of evolution which some scientists believe to have happened and they have some scientific data to support it.
