1. WHAT IS THE NATURE OF SCIENCE?

2. THIS IS THE SCIENTIFIC WORLD VIEW
The Universe Is Understandable.
The Universe Is a Vast Single System In Which the Basic Rules Are the same Everywhere
Scientific Ideas Are Subject To Change.
Scientific Knowledge Is Durable.
Science Cannot Provide Complete Answers to All Questions.

3. WHAT IS THE NATURE OF SCIENTIFIC INQUIRY?
Certain features of science make it distinctive as a means of understanding the world/universe
Those features are especially characteristic of the work of professional scientists, but anyone can use them to think scientifically about many aspects of everyday life

4. Science Demands Evidence
The validity of scientific claims is settled by referring to observations of phenomena
Therefore, scientists concentrate on getting accurate data

5. SCIENTIFIC LAWS AND THEORIES
Theory vs. Law
THEORY (WHY)
A Scientific Theory is an explanation for why something happens using observations

6. SCIENTIFIC LAWS AND THEORIES
A scientific law or a scientific theory is used to make predictions of events or relationships among data

7. SCIENTIFIC LAWS AND THEORIES
LAW (HOW)
A law governs a single action or situation

8. SCIENTIFIC LAWS AND THEORIES
Genuine scientific theories must be falsifiable by applying the scientific method (data collection and hypothesis testing)

9. SCIENTIFIC LAWS AND THEORIES
When the scientific community accepts a Law or Theory, it represents the best understanding of the explanations for the properties of a given system at that point in time

10. THE EXPERIMENTAL METHOD
The Experimental Method is usually considered the most scientific of all methods, the “method of choice”
The Experimental Method exerts the most control on data collection and interpretation

11. THE EXPERIMENTAL METHOD
An experiment is a study of cause and effect
It differs from non-experimental methods in that it involves the deliberate manipulation of one variable, while trying to keep all other variables constant
Experiments must be properly designed and include controls

13. HYPOTHESIS GENERATION
The use of logic and the close examination of evidence are necessary but not usually sufficient for the advancement of science
Scientific concepts do not emerge automatically from data or from any amount of analysis alone

14. SCIENCE EXPLAINS AND PREDICTS
Scientists try to make sense of observations by constructing explanations for observations that are consistent with currently accepted scientific principles
Such explanations—theories—may be either sweeping or restricted, but they must be logically sound and incorporate a significant body of scientifically valid observations

15. The credibility of scientific theories often comes from their ability to show relationships among phenomena that previously seemed unrelated

16. SCIENCE EXPLAINS AND PREDICTS
It is not enough for scientific theories to explain the observations that are already known
Theories should also explain additional observations that were not used in formulating the theories in the first place; that is, theories should have predictive power

17. SCIENCE IS SELF CORRECTING AND PROGRESSIVE
SCIENCE AS A WAY OF KNOWING
SCIENCE IS SELF CORRECTING AND PROGRESSIVE
