07/09/2007 09:19:00 Science is a process used to understand the physical universe. Involves testable evidence Not just a body of information Explains how nature works: a general set of principles that have explanatory  power Main concept: Science is limited to studying only the problems of the natural world that  can be understood by using the process of science.  Recognizing science: Based on natural laws (physics) Testable against natural world Conclusions are tentative Sub-concepts: Scientists deal with natural phenomena. (Can be observed, measured, and  tested) The processes of science are very successful in dealing with the limits of  science. Science is based on the assumption that the universe is orderly, reasonable,  and testable. A valid scientific theory is a well-defined, naturally occurring cause which  explains why and how a natural event occurs. Scientific theories are ALWAYS subject to change. Science doesn’t have all the answers. (Assignment 2) Characteristics of science  (must have all six) Consistent : Results of repeated observations are relatively similar and  compatible with well-established observations and limits. Observable : The event can be observed and explained and are limited to  basic human senses. Natural
