An organized body of

knowledge gathered over a

long period of time to explain

the world we live in.

Knowledge which has been

classified and made available

in word, life and our search for

truth.

It offers a way of

investigating and

building up a body of

knowledge.

It is a way of solving

problem, thus it is away of thinking.

It comes from the Latin

word SCIRE, which

means to know.

SCIENTIA means

knowledge.

The systematic study of the

inorganic world

A blend of chemical andphysical principles that

underlie our world and

define the nature of ourexistence.

Law Correlates a series of

observations

Essentially empirical Records and summarizes

concisely

Forms the results ofnumerous experiments

Directly observable

Theory Explains observations in

terms of what is

imagined Predicts what has yet

been observed

Remains tentative untilit becomes directly

observable

Not directly observable

Scientists normally do their

work as if the accepted

laws and theories were

true. But they are obliged to

keep an open mind in case

new information shouldalter the validity of any

given law or theory.
