  1. What is science?
    Science is a systematic process whose goal is to gain an understanding of how nature and the physical world work.
  2. What does science prove?
    Nothing. Science actually attempts to disprove ideas (hypotheses). Ideas that are not supported by data are discarded; ideas that are supported are accepted (NOT proven).
  3. Does science explain everything?
    No. Science is limited to solving problems about the physical and natural world. Explanations based on supernatural forces, values or ethics can never be disproved and thys do not fall under the realm of science.
  4. Is science always right?
    No. Science can be done poorly. New evidence can challenge/invalidate prior discoveries. The process of scientific discovery constantly refreshes knowledge by updating itself.
  5. Is any study that is done carefully and based on observation scientific?
    No. Scientific studies must follow the scientific method.
  6. Is science subjective or objective?
    Objective (Not influenced by feelings, interests and prejudices, unbiased) NOT subjective(influenced by feelings, interests and prejudices)
  7. In science, ________ overrules interest.
    evidence
  8. What are the two quality control measures used by the scientific community to eliminate bias?
    1) Independent duplication (two scientists independently get the same results) 2) Peer-reviewed journal (a journal that only publishes articles after they have been checked for quality by several expert, objective scientists from different institutions).
  9. Name three types of unscientific language:
    1) "scientifically proven" (science seeks to disprove) 2) emotional appeals (conclusions should be data-based) 3) strong language (no exaggerations should be made)
  10. Define fact.
    A fact is an observation that has been repeatedly confirmed and for all practical purposes is accepted as "true".
  11. Define hypothesis.
    An educated guess based on an observation. It can be disproven, but not proven to be true.
  12. Define Law.
    A statement that is accepted as true based on consistent observations. Laws describe, but do not explain. Unlike a theory, laws do not attempt to explain how.
  13. Define theory.
    A theory summarizes one or more hypotheses that have been supported with repeated testing. It is valid until there is evidence to dispute it. A theory is an accepted hypothesis. A theory is usually considered more important than a law because theories provide explanations.
