Understand the definitions of the terms provided in the options: A scientific theory, a scientific law, an experimental result, and a scientific hypothesis.
A scientific theory is a well-substantiated explanation of some aspect of the natural world that is based on a body of evidence and has stood the test of time. It explains 'why' or 'how' something happens.
A scientific law describes a consistent relationship observed in nature, often expressed mathematically, but it does not explain 'why' or 'how' the relationship exists.
An experimental result refers to data or observations obtained from a specific experiment, which may contribute to forming hypotheses or theories but is not a broad statement about nature.
A scientific hypothesis is a testable and falsifiable statement that serves as a starting point for experimentation. It is not yet supported by extensive evidence like a theory.
