Answer 2

SCIENCE is:  Science is the human effort to understand, or to understand better, the history of the natural world and how the natural world works, with observable physical evidence as the basis of that understanding. It is done through observation of natural phenomena, and/or through experimentation that tries to simulate natural processes under controlled conditions. 

SCIENCE is not:

Pseudoscience is a term used to describe a claim, belief, or practice presented as scientific, but which does not adhere to the scientific method. A field, practice, or body of knowledge can reasonably be called pseudoscientific when it is presented as consistent with the norms of scientific research, but it demonstrably fails to meet these norms.

Pseudoscience is often characterized by the following: contradictory, exaggerated or unprovable claims. An example of this science can be the belief of Evolution. 

How Science is practiced : Through continuous observations and many experimentations.
