Study Notes
Scientific Theories
- A scientific theory is a well-substantiated explanation for a set of phenomena, repeatedly tested and supported by a vast amount of data.
Everyday Language vs Science
- In everyday language, 'theory' implies a guess or speculation, but in science, it refers to a rigorously tested and widely accepted explanation.
Examples of Scientific Theories
- Gravity is an example of a scientific theory, as it explains the phenomenon of objects attracting each other.
Hypothesis to Theory
- A hypothesis becomes a scientific theory when it is extensively tested, supported by empirical evidence, and widely accepted by the scientific community.
Disproven Theories
- The geocentric model, which placed Earth at the center of the universe, was a theory later disproved by evidence and replaced by the heliocentric model.
Test your knowledge on scientific theories and learn how they differ from hypotheses. Understand the criteria that a hypothesis must meet to become a widely accepted scientific theory.
