In this activity, the student will learn about the
origin of the scientific method and how noted
scientists use it in their research.
Background
Probably as long as humans have been on earth, they have come up with explanations for
the workings of the world around them. In the past, these explanations often centered on
the supernatural. For instance, many believed that spirits, whose actions humans may or
may not be able to influence, were responsible for nature. Everything from the cause of a
disease to the motion of the planets could be accounted for with this explanation without
the need for proof.
In contrast to this view, modern scientists try to derive explanations based on evidence
gained from observation and testing. The method by which answers are sought varies
depending on the area studied, but it generally consists of these steps:
•
•
•
•
•
•
Make observations
Identify a problem
Form a hypothesis (a possible explanation for the problem)
Test the hypothesis through experimentation
Collect and record data from the experiment(s)
Draw conclusions based on the experimental results
This modern investigative approach, known as the scientific method, did not arise
overnight, but evolved over centuries through the efforts of many individuals and groups.
One such individual was Hippocrates (hip-POCK-kruh-tees), the “Father of Medicine.”
Born in Greece in the 5th century BC, Hippocrates is important in The RECONSTRUCTORS
story for his use of willow bark extract as a pain reliever. As a physician and teacher,
Hippocrates championed a rational approach to disease and healing. He contributed
greatly to what we today call the scientific method.
Instead of thinking of disease as the work of supernatural forces, treatable by magic or
witchcraft, Hippocrates looked for natural causes. He believed that the experience gained
from his own observations of patients, or from previous medical observations by others,
could be used to help diagnose disease and to suggest an appropriate treatment.
The following page provides a short synopsis of Hippocrates’ life and work.

Hippocrates
Most people regard the Greek physician Hippocrates (hip-POCK-kruh-tees) as the “Father of
Medicine.” Hippocrates was born on the island of Kos (COSE) in about 460 BC and died about
377 BC. Kos was famous for hosting a temple to the Greek god Ascelapius (esk-ah-LAP-ee-us),
the god of healing and physicians. Men and women suffering from every type of disease came
from all over the ancient world to consult the priests of the temple and ask the god for healing. It
was not surprising, therefore, that there were also many physicians on Kos to tend the sufferers
visiting the shrine. Over time, the physicians of the island developed a reputation for skill in their
craft. Certain families of physicians, called Asclepiads (es-KLEEP-pea-ads) in honor of the god,
were particularly renowned for their knowledge. Hippocrates came from such a family and was
eventually regarded as the foremost physician in the history of Kos and of the entire ancient
Mediterranean world.
Hippocrates traveled widely throughout his world, visiting Greece, the islands of the
Mediterranean, and Asia Minor (modern day Turkey). He taught many students who later formed
a kind of network dedicated to preserving the memory and teachings of their master. There were
many books in the ancient world supposedly written by Hippocrates. Historians have identified
about seventy such books, of which sixty still exist. Hippocrates wrote some of these, while
others were written by his pupils, who then signed Hippocrates’ name as the author. This was a
common practice in the ancient world. Together with the later teachings of a physician named
Galen (GAY-len) these writings, called the Hippocratic Corpus or Hippocratic Collection, were
the main sources of medical theory for most of Western history.
Hippocrates and his pupils believed that the body was a delicate system of balances. Various
substances and activities inside a person had to be balanced with each other, and things going on
inside the body had to be balanced with things going on outside. When this balance was upset, a
person became ill. Hippocratic physicians treated their patients by carefully regulating their diet
and exercise and by giving them various kinds of medications that they believed would restore
balance. The followers of Hippocrates also believed that climate was important for health and
would sometimes recommend that a patient seek a healthier place to live as a way of easing
suffering.
Hippocrates was very important not only for his medical theories but also for his beliefs about the
ways in which a physician should think and act. He held that illness should be regarded as a
natural phenomenon, not primarily as something stemming from the wrath of the gods or the
meddling of evil spirits (although neither he nor his pupils denied the existence of gods and
spirits). He thought that, when confronted with a disease, a doctor should seek out a natural cause
and attempt to formulate a cure. For instance, Hippocratic physicians held that epilepsy, which
had been known as the “sacred disease” because the seizures were believed to be due to the touch
of divine spirits, was in fact simply a natural disorder of the body.
Hippocrates also believed that a doctor should be selflessly dedicated to his patients. He should
take solemn oaths never to harm the people in his care. In fact, the motto “first do no harm” has
been widely quoted as Hippocrates’ first piece of advice to aspiring young doctors. Even today,
doctors in the West take a formal series of pledges when they receive their degrees in medicine.
These pledges are called the Hippocratic oath.

Learning Objectives
The student will:
• Research the life of a scientist and how his/her work utilized the scientific
method.
• Create a presentation on the scientist.
Materials
•
•
•
Computer with Internet access and word processing or presentation software
Science Stars Student Activity Sheet
Poster boards
Procedure
1.
Prior to the beginning of class, write the steps of the scientific method on the
board.
2.
Tell students that they will need to make an outline for a new movie. The movie
will be based on the life of a scientist and how his/her work utilized the scientific
method.
3.
Describe the scientific method.
4.
State that one person whose work was important in the development of the
scientific method was Hippocrates.
5.
Identify who Hippocrates was in terms of the Reconstructors web adventure and
give an example of how his work contributed to what we now think of as the
scientific method. For instance, Hippocrates was able to develop a system by
which he could determine which physical symptoms lead to death. This method
was a form of evidence-based medicine and the beginning of the scientific
method.

6.
Hand out the Science Stars Student Activity Sheets and ask each student or group
of students to research a scientist. Suggested research subjects are: Dorothy
Hodgkin, George Washington Carver, Barbara McClintock, Charles Darwin,
Rosalind Franklin, Galileo Galilei, Gertrude Elion, Isaac Newton, Benjamin
Banneker, Marie Curie, Francesco Redi, Leonardo daVinci, and Percy Julian.
7.
Inform students that they will need to present their research outline as a poster or
by using presentation software.
8.
Have each student or each group make an outline and present it to the class.
Next, have the class vote on the best candidate for the full-length movie.
