Document Summary
Scientific fact : info that can be independently verified by a trained person. Law of nature : generalization about how matter and energy (for both biotic and abiotic) behave; results from inductive reasoning and repeated observations. A description, laws do not govern the universe. Theory : an explanatory statement or set of statements derived from facts, laws, and confirmed hypotheses. The terms law and theory have different meaning in science than in common usage. Ex. cell theory, fluid mosaic theory of membranes, the sliding filament theory of muscle contraction **not all complete, we know there more were trying to learn about**. Scientists use the word hypothesis for what is commonly called a theory. The different usages can be confusing; people conclude that something like evolution is just a theory, meaning a guess or conjecture. Evolution is a fact but the theory is not a hypothesis in the scientific sense of the term.
