What does scientific method start with?
The scientific method starts when you ask a question about something that you observe: How, What, When, Who, Which, Why, or Where? For a science fair project some teachers require that the question be something you can measure, preferably with a number.
Which question Cannot be answered by an experiment?
Questions that cannot be answered through scientific investigation are those that relate to personal preference, moral values, the supernatural, or unmeasurable phenomena.
What type of questions Cannot be solved by scientific method?
Science can answer many questions about the world in which we live, but it cannot answer questions that cannot be verified as verification is how the scientific method works. The scientific method works because scientists are able to verify or dismiss a hypothesis based upon the data that they collect.
What does a sound scientific conclusion most likely rely upon?
What does a sound scientific conclusion most likely rely upon? Scientists with different educational backgrounds can come to different interpretations of the same data. No guess as to the answer to a scientific question can be considered a valid hypothesis since hypotheses are made before data collection.
What skill is a scientist using when they record the sounds a dolphin makes?

What are the methods of natural science?
An examination of scientific theories and their logic in life and physical sciences. Experimental design, novel device production, data analysis and modeling will be discussed using examples drawn from primary source material in the natural sciences.
Is science related to math?
In many ways, math is closely related to science. Mathematics is such a useful tool that science could make few advances without it. However, math and standard sciences, like biology, physics, and chemistry, are distinct in at least one way: how ideas are tested and accepted based on evidence.
