Deductions from a hypothesis may be tested by making further observations or by running an experiment. Experiments not only test hypotheses, but often lead to new problems and questions. Controls are necessary for comparison draw conclusions from the behavior of the experimentals. Use results of deduction testing to reject, accept or modify hypothesis Go through repeated rounds of making ever more sophisticated hypotheses, generating deductions and testing deductions. Once scientists repeatably test a hypothesis and find it holds true to its deductions, the hypothesis then gains the status of theory.
Science is an ongoing process that is a self-correcting way of knowing.
Try to replicate the observations and experiments of others to check on their conclusions. Share information through publications, seminars, meetings and personal communications. What really advances science is not just an accumulation of facts, but a new concept that collectively explains observations that previously seemed to be unrelated. Newton, Darwin and Einstein stand out in the history of science because they synthesized ideas with great explanatory power. Scientific theories are comprehensive frameworks which are will supported by evidence are are widely accepted by the scientific community.
