  1. Science Terms

  2. OPINION A Persons belief or idea

  3. Fact Something that is accepted as being true with supporting data.

  4. Criteria Standards to judge facts to make decisions ( ex- grading criteria)

  5. Observation The act of noticing or perceiving a fact or occurrence of some scientific phenomenon using the senses.

  6. Inference The process of drawing a conclusion based only on what one already knows. (ex- You hear rain on the roof so you infer that the sky is grey– If you look to be sure that is an: Observation)

  7. Theory Well- substantiated or proven explanation of some aspect of the natural world. Confirmed through observations, laws, inferences and successfully confirmed hypotheses. (ex. The Big Bang Theory- how the universe was formed by a gigantic explosion)

  8. Law A description about how the natural world behaves under stated circumstances. (ex- For every action there is an equal and opposite reaction)

  9. Science • A way of knowing about the natural world, based on observation and experiments. These can be confirmed or disproved by other scientists using accepted scientific techniques.

  10. Citizen A citizen is someone who lives in a particular region such as a town, city, state, or country. A citizen will also be loyal to the area in the local issues that affect them. They may join or support committees (conservation, recreation etc..) school board, Scouts, and many others.

  11. Citizen of the World A person who studies far reaching problems that affect not just local areas and makes us aware of these problems and guides us to help solving them.

  12. Problem A question that needs an answer (who, what, when, where, why, how)

  13. Research Finding information to help solve the problem or answer the question

  14. Hypothesis An educated guess. A possible solution to a problem about the natural world that can be tested.

  15. Experiment A data gathering procedure used to test a hypothesis. Contains a control and ONE variable

  16. Observation Using one or more of your senses to notice objects or events.

  17. Conclusion It supports or does not support the hypothesis A result that has been repeatedly confirmed.

  18. Report Sharing your findings to replicate or confirm your conclusion

  19. Repeat You should repeat the experiment if your conclusion does not support your hypothesis.

  20. Control The part of the experiment that does not change. Allows comparison for the experiment. Used to show that the results of an experiment are actually a result of the condition being tested.

  21. Variable The part of the experiment that is changed. It is the one factor being tested in an experiment

  22. Why must we have only one variable in an experiment? If there is more than one variable, we will not know what caused the results we observed, thus making our experiment invalid.
