An explanation supported by evidence (e.g., “Rayleigh scattering explains why the sky appears blue”). Theories are the highest form of scientific knowledge. Yet to be unproven.
- A scientific theory is a well-substantiated explanation of natural phenomena, supported by a large body of evidence and repeatedly tested through experiments and observations.
- Example: The theory of evolution explains the diversity of life on Earth and is supported by genetics, fossils, and other evidence.
- Key Point: Theories are not “guesses” but comprehensive explanations that can be refined as new evidence emerges.
