The Scientific Approach In Chemistry (Observation, Hypothesis Theory and Law)

Over the science has developed through a series of discoveries which started off as observed natural phenomenon which had to explained.This was done by using scientific method in systematic manner.

(1) Observation:
Different people observe a phenomenon in different ways.Some of us observe something very critically to extract from it a new point.Observation is a basic tool to go forth for elaborating a phenomenon but it may vary from person according to his own skill of elaboration.Observation is thing is one of the scientific approaches in chemistry.

(2) Hypothesis:
When phenomenon is observed; a scientific ponders over it and carries out relevant experiments.He sieves through the data and arrives at possible explanation for the nature of the phenomenon.This explanation ; which is still only a trial idea is called hypothesis.It may or may not undergo a change as a result further investigation and accumulation of more knowledge or facts.

(3) Theory:
The scientist conveys his hypothesis to other workers of the same field for the discussion and for further experimentation .When the hypothesis is supported by a large amount of different types of observations and experiments,then it becomes a theory.

(4) Scientific Law:
A theory which is tested again and again and found to fit the facts and from which valid predictions may be made is then known as scientific law or principle.
