Presentation Transcript

  1. The Nature of Science Theory, hypothesis, and law

  2. Nature of Science Making observations, asking questions, gaining understanding and seeing patterns in nature. Terms to understand include: Hypothesis, Scientific theory, scientific law, fact, and belief

  3. Hypothesis *Based on background observations and knowledge *(If/then statement – causal or correlational relationship *Educated Guess

  4. SCIENTIFIC LAWS • based on repeated experimental observations describing some aspects of the universe. • Applies under same conditions • Implies causal relationship • EQUATION

  5. Example • Law of Gravitational Force: • represented by an equation F = G × [(m1m2)/r²]F = G×[(m1m2)/r²] • Kepler’s Law of Planetary Motion

  7. THEORY • A Principle supported by evidence – lots and lots includes • Factual evidence, proven hypothesis, laws of nature • Theory never becomes a law- have separate roles in science – a law can strengthen a theory

  8. Examples of Theory • Big Bang Theory • Theory of heliocentricism • Theory of Evolution • Theory of relativity

  9. Scientific Facts • - a basic statement established by experiment or observation. Generally, a • fact is a very elementary statement that are true Examples: Fossils show increased complexity closer to the surfaceWater boils at 212 degrees Celsius at sea level.

  10. Belief Not scientifically provable Examples: Rabbit feet provide good luck. Friday the 13th is a bad luck day!
