3. Data & Observations Data Data –Measurements and calculations taken from an experiment or observation –Should be objective (everyone “should” use a ruler the same way.) –THE METRIC SYSTEM is always used in Science

4. Facts Facts are pieces of information that are verifiable and true…right now. Facts are pieces of information that are verifiable and true…right now. Facts can change Facts can change Over time, further observations and data collection can change facts Over time, further observations and data collection can change facts –“How many planets are there?” –“What are the names of the Kingdoms of living things?”

5. Theory A well-tested explanation that unifies a broad range of observations A well-tested explanation that unifies a broad range of observations Scientists are confident that NO amount of observation or experimentation will change a theory Scientists are confident that NO amount of observation or experimentation will change a theory –“Theory of Evolution” –“Cell Theory”

6. Law Knowledge of the world that scientists believe to be true…regardless of time, space, or place in the universe Knowledge of the world that scientists believe to be true…regardless of time, space, or place in the universe –“Law of Gravity” –“Newton’s Laws of Motion” …these are true on every planet, for every object in the Universe!
