History of Science
In the late 1400s, the painter Leonardo da Vinci gather data on the human body and wants to find evidence that the human body is microcosm. Artist, scientist, and mathematician gathers information about how optics and hydrodynamics ever worked.

In the late 1500s, Copernicus had discovered the model in which Earth and planets revolve around the sun called heliocentrism. " (1) This model form the center of our solar system. (1)
Johannes Kepler proposed " the laws of planetary motion, and Galileo invented the telescope that is used to study the sun and planets." (1) Isaac Newton has developed " his laws of motion in the 1600s. "(1)
In the 1700s, Ben Franklin discovered "electricity in the lightning, and Antoine Lavoisier developed the law of conservation of mass. " (1) John Dalton introduced the "atomic theory that stated that all matter is comprised of atoms that combined to form molecules. "(1)
Gregor Mendels "advanced the basis of modern genetics in his laws of inheritance ." (1)
Albert Einstein is "best known for his theory of relativity, which dominate in the beginning of the 20th century." (1)
In the 21st century, James D. Watson and Francis Crick "had discovered the structure of DNA." (1) At the same time, the first draft of the human genome was completed leading to the extensive understanding of DNA and advancing the study of genetics and their role in human biology as a predictor of diseases and other disorders.
These scientific discoveries are the basis for how the scientific method led to their discoveries.
The basics for the scientific method are that:
1. "State or make an observation or observations." (1)
2. "Ask questions about the observations and gather data about them." (1)
3. "Form a hypothesis or a tentative description of what is been observed and make predictions based on that hypothesis." (1)
4. "Test the predictions or hypothesis in an experiment that can be reproduced."(1)
5. "Analyze the your data and draw conclusions." (1)
6. "You can accept or reject the hypothesis or modify the hypothesis if necessary." (1)
7. " Reproduce the experiment until there are no discrepancies between observations and theory." (1)
In the scientific method,
1. "The hypothesis must be testable and falsifiable."(1)
2. The research must "involve deductive reasoning, not inductive reasoning. " (1) Deductive reasoning is "the process of using true premises to reach a logical true conclusion." (1)
3. The experiment must "include an independent variable and a dependent variable. " (1) "An independent variable does not change and depend on the dependent variable. "(1)
4. An experiment "should have an experimental group and a control group. " (1) "The experimental group is compared against the control group. " (1)
A hypothesis can become a "theory if there are extensive testing that must occur throughout multiple disciplines by separate or different groups of scientists." (1) In science, " a theory is something that is very well supported by observation and experimentation. " (1)
When " conducting a research project, scientists must observe the scientific method to collect measurable data in an experiment related to a hypothesis. The results aimed to support or contradict a theory." (1, 2)

Example of using the Scientific Method

Observation.

Science requires strict and careful observation that points to an interesting question. One observation that points to an interesting question is by the Scottish biologist Alexander Fleming in the 1920s. Alexander Fleming observe that plates of bacteria that he grew were contaminated with some mould. ( 1, 2, 3) The area around the mould looked free of bacteria growth. ( 1,2,3) He began to form a cause and effect relationship that the mould may prevent the bacterial growth. ( 2,3) His observation led to a conclusion that penicillin could be used to treat bacterial infections. (1, 2,3)

Hypothesis.
A hypothesis is a proposal generated by an observation.(1, 2, 3) In Fleming's investigation of antibiotic of mould, the hypothesis form is that if "bacteria were introduced to the filtrates from mould, the bacteria will die." (2)
"Good hypothesis are testable and falsifiable. " (2, 3) The hypothesis can be subjected to an "observable test and can be proven to be false."(2) For example, in the Fleming's studies of mould, the "hypothesis can be falsified because a test in which bacteria can grew in the presence of the filtrate of the mould would have disproven the hypothesis. " (2, 3)

Testing
Scientific studies involve a "test with a control group and an experimental group. " (2, 3) The scientist conducts the experiment on the control group as well as the experimental group. (2, 3) The only difference is that the investigators does not subject the control group to the factor being tested, which is the variable. (2)
In an experiment testing Fleming's hypothesis, a scientist will introduce "filtrates of mould to cultures of bacteria on glass plates, which serve as an experimental group. " (2, 3) A control group can "contain cultures of bacteria with no addition of mould filtrates." (2, 3) Both groups will be subject to exactly the same conditions. (2)

Conclusion
A conclusion involves "analysis and interpretation of the data gathered during the testing phase, which allowed researchers to form conclusion based on the data." (2, 3) A valid conclusion will reflect the hypothesis. (2)
