विविध नैसर्गिक गोष्टींची चिकित्सा करून त्यांबद्दलचे ज्ञान मिळवणे आणि जुन्या ज्ञानाची दुरुस्ती करून त्याचे नव्या ज्ञानाबरोबर संकलन करणे यांसाठीच्या पद्धतींच्या संचांला वैज्ञानिक पद्धती असे म्हटले जाते.] वैज्ञानिक म्हणून गणली जाण्यासाठी ही पद्धती ही नेहमी प्रायोगिक आणि मोजमाप करता येईल अशा पुराव्यांवर अवलंबून असते. त्याचप्रमाणे तर्कवादाची काही ठराविक तत्वेदेखिल यामध्ये पाळली जाणे अपेक्षित असते . The scientific method is a body of techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.
The scientific method is an ongoing process, which usually begins with observations about the natural world. Human beings are naturally inquisitive, so they often come up with questions about things they see or hear and often develop ideas (hypotheses) about why things are the way they are. The best hypotheses lead to predictions that can be tested in various ways, including making further observations about nature. In general, the strongest tests of hypotheses come from carefully controlled and replicated experiments that gather empirical data. Depending on how well the tests match the predictions, the original hypothesis may require refinement, alteration, expansion or even rejection. If a particular hypothesis becomes very well supported a general theory may be developed.
Although procedures vary from one field of inquiry to another, identifiable features are frequently shared in common between them. The overall process of the scientific method involves making conjectures (hypotheses), deriving predictions from them as logical consequences, and then carrying out experiments based on those predictions. A hypothesis is a conjecture, based on knowledge obtained while formulating the question. The hypothesis might be very specific or it might be broad. Scientists then test hypotheses by conducting experiments. Under modern interpretations, a scientific hypothesis must be falsifiable, implying that it is possible to identify a possible outcome of an experiment that conflicts with predictions deduced from the hypothesis; otherwise, the hypothesis cannot be meaningfully tested.
The purpose of an experiment is to determine whether observations agree with or conflict with the predictions derived from a hypothesis. Experiments can take place in a college lab, on a kitchen table, at CERN's
