Scientist Method
Using the
Scientist Method
All of us have benefited greatly
from the use of scientist method in solving problems such as those dealing with
the maintenance of health, the production and preservation of foods, the
construction of our homes and the improvement in communication and
transportation. Not only have our ways of living changed, but people themselves
have also been changed. Today we are better able to explain happenings which
used to be considered strange and mysterious. Although there is still need for
improvement, we are now generally less fearful than our fathers and
grandfathers were. We are also more critical in our thinking than our
ancestors.
This lesson should help you
understand how the use of scientist method has improved living conditions and
changed people. It should also help you understand how you can make better use
of scientist method in your everyday living.

Better control of Diseases: If you had been born two
hundred years ago, you would have had about one chance in eight of living to be
one year old. In other words, in those days about seven out of eight babies
died before reaching their first birthday. Suppose you had been and unusually
strong little fellow and had lived through that first year. Very likely, before
you were six years old, you would have had smallpox and by the time you reached
the age of twelve, you would undoubtedly have had measles, whooping cough,
scarlet fever and diphtheria. Even then your even influenza, once started,
spread through a community. Life was most uncertain. A person who lived to be
more than thirty years of age was indeed fortunate. It is unbelievable that
such conditions could have existed so short a time ago. Today babies are born
in hospitals where there is little likelihood of their getting a disease. Young
people are treated to protect them against smallpox, diphtheria and typhoid
fever. Today a person can expect to live to be almost seventy years old. In
other words, more than thirty years been added to the expected length of man’s
life. These changes have been made possible by use of the scientist method to
solve such problems as the causes of disease and its prevention.
Better Sanitary Conditions: It is difficult of imagine what
sanitary conditions in some of our larger cities were like only one hundred
years ago. Into the narrow, unpaved and poorly drained city streets household
garbage and other refuse were thrown. Animals wandered through the streets,
feeding upon the garbage. Outdoor toilets were common, many of them situated
where human wastes drained into wells form which people obtained drinking
water.
Today our cities streets are paved
and well drained and they are cleaned regularly. It is against the law to throw
garbage in the streets. Sewage from all section of a city is carried through
sealed pipes to disposal plants. Through the use of the scientific method it
has been demonstrated that unsanitary conditions cause the spread of disease
like typhoid fever, cholera and dysentery. Today most city governments have
departments of sanitation which deep the cities clean and thereby prevent the
spread of certain disease.
