SCIENTIFIC METHOD
SCIENTIFIC
METHOD is away to solve problems by following definite and
regular ways
1) Formulating Problems
Problems are scientific questions to
solve. Problems are expressed in open questions those are question where its answer is in form of
statement, not “ yes “ or “ no” answer. Also select any problems possible to
solve by experimen.
2) Conducting
Preliminary Observation
It is to colllet information on any
thing relate to the probelm. We can do it through experience, varios sources of
knowledge, consultation to experts, and by reading all reference related to the
problem
3)&nbrp; Arranging Hypothesis
Hyppotesis is any idea or provisional
assumptions on solving problems proposed in the scientific research. You should
remember if you get that results of your hypothesis testing is not true, it
does not mean that the research you conduct is wrong.
4) Conducting Experiment
Experiment is desgned and implemented to
test proposed hyphotesis.when doing experiment, you should calcute all variables
influecing the experiment. Try to make only on independent variable during the
experiment! For a good result, replcate it!
5) Taking Conclusions
Conclusions is a result expressing
relation between experiment and hyphotesis. Conclusions you take may conform to
the hypothesis but it is also possible to be contarary to the hypothesis. If
conslusions conforms to hypothesis, you can provide with thought for further
research. However, if the hypothesis that you arrange does not conform to the
conclusions, nver change data you obtained! If you have sufficiet time, it is
better for you to do the experiment again.
Example of scientific
method application in research on
malaria disease. Malaria is derived from two words, those are mal and aria meanin gbad weather/air. In the past time, people though that
malaria was caused by bad weather coming from swamps. In 1880, a French
pyhsician named Charles Laveran treated a soldier suffering malaria in Algeria.
Laveran exanamed the soldier’s blood under microscope. He found that thatthe
soldier’s blood cells contained strange objects similar to ring. Laveran
predicted that the strange, object was
cause of malaria since it was not found
in red blood cells of healthy people. To prove object his hypothesis Laveran
injected the blood of malaria sufferer into a healthy person. After injection,
the healthy person was infected by mlaria disease.
