Science is knowledge but where does this knowledge come from? Scientist use a method called the scientific method to gather information in order to create theories.
When we perform experiments, we usually follow a plan called the scientific method. This method is not a set of rules nor was it thought up by a person. Over time, the scientific method has evolved by many scientists who wanted to communicate their results to other scientists. The scientific process allows the experiment to be repeated by someone else and the results to be communicated in a similar way.
The scientific method is logically thought out. Experiments follow the same process in which people use to solve their problems and answer questions.
