1 The Scientific Method

2 The scientific method (or simply scientific method) is a body of techniques for investigating
phenomena, acquiring new knowledge, or correcting and integrating previous knowledge. [1] To be termed scientific, a method of inquiry must be based on empirical and measurable evidence subject to specific principles of reasoning.[2] The Oxford English Dictionary says that scientific method is: "a method or procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses."[3]

3 The chief characteristic which distinguishes a scientific method of inquiry from other methods
of acquiring knowledge is that scientists seek to let reality speak for itself, supporting a theory when a theory's predictions are confirmed and challenging a theory when its predictions prove false.

4 However most often the scientific method is taught as “THE” method for creating
understanding. It is very dogmatic in its nature. 1. Observe 2. Ask a question (based on the observation) 3. Propose a testable answer (the hypothesis) 4. Test and collect data on the proposed answer 5. Come to a conclusion based on the results of the test.

5 There’s much more to this.
The test must be so guided as to test only the one variable that could create a change. The test must be repeatable so others can see the results for themselves and to make sure the “reported” results are true. The results must be measurable and repeatable.

6 The role of the hypothesis is to help
create a testable proposal to a question. The hypothesis guides the questioner in setting up the test itself.

7 ALL of these are good practices.
1. Observe 2. Ask a question (based on the observation) 3. Propose a testable answer (the hypothesis) 4. Test and collect data on the proposed answer 5. Come to a conclusion based on the results of the test. But Are they always done in the order listed? Are they all necessary to gain new knowledge from a new observation? Can they be practiced in any order ? Are there more practices than what is listed that are used to gain scientific knowledge? Is there some purpose or advantage to putting these practices into a step by step order?
