Science not as a noun…but a a process, a set of activities, a way of proceeding and thinking.
--Tinker & Thornton, 1992

Session 2 objectives
Appreciate that: Scientists use a wide range of inquiry
methods Science is based on observations and
hypotheses within a testable framework of ideas
Science is collaborative Scientific “truth” evolves over time Non-scientific ideas are sometimes presented
as scientific to the general public

So, what is science?
Science is a set of methods designed to describe and interpret observed or inferred phenomena, past or present, and aimed at building a testable body of knowledge open to rejection or confirmation.
--Michael Shermer
Director of Skeptics Society

So, what is science?
Science is a limited way of knowing, looking at just the natural world and natural causes. There are a lot of ways human beings understand the universe --through literature, theology, aesthetics, art or music.
--Dr. Eugenie Scott
Executive Director National
Center for Science Education

Terms Used in Describing the Nature of Science*
Fact: In science, an observation that has been repeatedly confirmed and for all practical purposes is accepted as "true." Truth in science, however, is never final, and what is accepted as a fact today may be modified or even discarded tomorrow.
*Adapted from Teaching About Evolution and the Nature of Science by the National Academy of Sciences (Washington, D.C.:
National Academy Press, 1998).

COSEE California
Terms Used in Describing the Nature of Science*
Hypothesis: A tentative statement about the natural world leading to deductions that can be tested. If the deductions are verified, the hypothesis is provisionally corroborated. If the deductions are incorrect, the original hypothesis is proved false and must be abandoned or modified. Hypotheses can be used to build more complex inferences and explanations.

COSEE California
Terms Used in Describing the Nature of Science*
Law: A descriptive generalization about how some aspect of the natural world behaves under stated circumstances.
![Page 19: COSEE California Communicating Ocean Sciences Session 2: The Nature of Science.](https://reader036.fdocuments.us/reader036/viewer/2022070415/56649f175503460f94c2d3ea/html5/thumbnails/19.jpg)
COSEE California
Terms Used in Describing the Nature of Science*
Theory: In science, a well-substantiated explanation of some aspect of the natural world that can incorporate facts, laws, inferences, and tested hypotheses.
![Page 20: COSEE California Communicating Ocean Sciences Session 2: The Nature of Science.](https://reader036.fdocuments.us/reader036/viewer/2022070415/56649f175503460f94c2d3ea/html5/thumbnails/20.jpg)
COSEE California
The contention that evolution should be taught as a "theory, not as a fact" confuses the common use of these words with the scientific use. In science, theories do not turn into facts through the accumulation of evidence. Rather, theories are the end points of science. They are understandings that develop from extensive observation, experimentation, and creative reflection. They incorporate a large body of scientific facts, laws, tested hypotheses, and logical inferences. In this sense, evolution is one of the strongest and most useful scientific theories we have.
