Scientific Investigations Parts GRM 12.5 1. Understanding the problem.  Scientists begin with a problem or question that presents itself during the examination of some data or phenomena. The problem may be generated by industry or by government, or it may arise in the speculative atmosphere of the laboratory. 2. Formulating a hypothesis.  The next step involves the formulation of a hypothesis. These are proposed as solutions to a problem or as explanations for some strange or unexpected phenomenon. There may be a number of competing hypotheses, each offering a solution to or explanation of the problem. 3. Deducing the implications of the hypothesis.  Having selected the most plausible hypothesis, the scientists' next step is to determine what observable consequences would have to follow if it were correct. Such inferences often take the form 'If is the case, then would have to occur under such and such conditions.' 4. Testing the hypothesis.  Once the scientists have deduced what consequences should follow if the hypothesis is correct, they can devise and conduct tests to ascertain whether these consequences do indeed follow. The tests should be designed to confirm the hypothesis with observable consequences, or to establish that the consequences do not follow. 5. Evaluating the hypothesis.  Finally, the scientists evaluate their observational and experimental findings and decide to reject the hypothesis, to revise it in some way that the evidence suggests is appropriate, or to consider it confirmed and adopt it

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
