What are the steps used to solve a problem in a scientific way?

Answer 1

Observe the problem as accurately and precisely as you can. Measure relevant quantities (of whatever is involved).

Think up some possible explanation for this problem that is consistent with known science, and with logic, and with your observations and measurements.

Test that hypothesis with further observation and experimentation.

Either accept the hypothesis, if it works out, or if it doesn't, try to produce a better one, and then test that.

When you have a confirmed hypothesis, it graduates to the status of a theory. Using this theory, you now have a basis to understand the original problem well enough to devise a solution for it. Of course, the learning process in science never stops, so as you solve or try to solve the problem, further data are likely to be observed which could enable you to further refine your theories and problem-solving technique.
