Scientific Revolution: The scientific method

For centuries, people based their beliefs on their interpretations of what they saw going on in the world around them without testing their ideas. People would read the bible for answers to all there questions. The Greek and Christianity believed that the earth was located at the center of the universe and that other planets revolved around it. Aristotle theory was that heavy object reached the land faster than a lighter object. His theory was believed by people for 1500 years. Years later they conducted an experiment and found out that there observations were not true. The questioning of everything and how things worked was later solved by the Scientific Revolution.

The scientific method is a way to ask and answer scientific questions by making observations and doing experiments. The scientific method has four steps to its process. Scientist first get there theory or the question they have in mind. They then get a hypothesis/educated guess, and they design an experiment. They would record data and repeat it several times to make sure there conclusions are accurate and similar. This was a great way to support opinions and understandings. Scientist use the scientific method to search for the cause and effect in an experiment.

Aristotle had a theory that heavy objects fell faster than lighter objects. And for about 1,500 years, people believed him. An example of an experiment that uses the scientific method would be to find out if a cube of clay or if a piece of wood would float or sink. I would first conduct a question and support it with my hypothesis. I Would then do my experiment at least 3 times to make sure my answer is accurate. My last step would be to accumulate all my data and form a conclusion.
