  1. Key Science Terminology What do people know about science?

  2. Science • A way (or process) of knowing about the world based on observations and facts that can be proved or disproved by other scientists using accepted techniques.

  3. Scientific Law • A description of how a natural phenomenon will occur under certain circumstances. • Ex: An object in motion tends to stay in motion.

  4. Fact • A natural phenomenon repeatedly confirmed by observation • Ex: Venus takes 25 days to circle the sun, earth 365 days, Sun rises in the east.

  5. Hypothesis • A possible and testable statement that answers a question about an observation. • Often presented as if__then__. statements.

  6. Scientific Theory • A well accepted explanation of some aspect of the natural world that includes many confirmed observations, laws, and successfully proven hypothesis. • Predicts future occurrences • Can be tested • Is falsifiable (can be disproved with new evidence and data) • Ex: Plate Tectonics, Einstein's Relativity (e=mc2), Darwin's evolution.
