Learn about 'scientific method'
The scientific method is a body of techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge. To be termed scientific, a method of inquiry is commonly based on empirical or measurable evidence subject to specific principles of reasoning.
- Observe some aspect of the universe.
- Invent a tentative description, called a hypothesis, that is consistent with what you have observed.
- Use the hypothesis to make predictions.
- Test those predictions by experiments or further observations and modify the hypothesis in the light of your results.
- Repeat steps 3 and 4 until there are no discrepancies between theory and experiment and/or observation.
When consistency is obtained the hypothesis becomes a theory and provides a coherent set of propositions which explain a class of phenomena. A theory is then a framework within which observations are explained and predictions are made.
