While theory in colloquial usage may denote a hunch or conjecture, a scientific theory is a set of principles that explains an observable phenomenon in natural terms. [127] [128] "Scientific fact and theory are not categorically separable", [129] and evolution is a theory in the same sense as germ theory or the theory of gravitation. [130]

Finally, there is a more research-intensive approach that involves interviewing students for the purpose of generating the items that will make up a concept ...

However, a fact is defined by the conditions in which the observation or experiment took place, and may not be a fact in other circumstances.
There might be more science now, but it feels like the current trends can't compare to the 20th century in terms of discoveries that change the world. #6 Image credits: sciencefunn
A scientific law is "inferred from particular facts, applicable to a defined group or class of phenomena, and expressible by the statement that a particular phenomenon always occurs if certain conditions be present". [7] The production of a summary description of our environment in the form of such laws is a fundamental aim of science.
Scientific evidence is evidence that serves to either support or counter a scientific theory or hypothesis, [1] although scientists also use evidence in other ways, such as when applying theories to practical problems. [2] Such evidence is expected to be empirical evidence and interpretable in accordance with the scientific method.
