The Nature of Scientific Inquiry “Tell me and I’ll forget, show me and I’ll remember, involve me and I’ll understand” Hypothesis Hypothesis Theory Theory Scientific Law Scientific Law – An educated guess based upon observation. – A rational explanation of a single event or phenomenon – based on observation and has not been proved. – Can be supported or refuted by experimentation or continued observation. – An explanation of a set of related observations or events – Based upon proven hypotheses and verified multiple times by detached groups of researchers. – One scientist cannot create a theory; he can only create a hypothesis (Theory of Evolution, Theory of Relativity, Quantum Theory) – Accepted to be true and universal – Accepted at face value based upon fact they have always been observed to be true. (Law of Gravity, Law of Thermodynamics) (Law of Gravity, Law of Thermodynamics)
