The Nature of Science

2010 Virginia Science SOL


The nature of science

Equipped with his five senses, man explores the universe around him and calls the adventure Science. 


Understandable

THE NATURAL WORLD IS

UNDERSTANDABLE


The nature of science

The Natural World is Understandable

The natural world is understandable through the careful collection and critical analysis of empirical evidence.

Every discipline in modern science has derived its laws, principles, paradigms, and theories through this process.


Evidence

SCIENCE DEMANDS

EVIDENCE


The nature of science

Science Demands Evidence

Scientific knowledge involves a combination of observations and inferences.

Scientists use data to make inferences and formulate explanations of phenomena.

Data can be obtained through experimentation or observation.


The nature of science

Scientific methodology

Scientists apply various methods in doing research.

There is no universally accepted “scientific method” agreed upon by the scientific community.

Science does demand that evidence be empirically collected and analyzed.


Logic and imagination

SCIENCE IS A BLEND OF

LOGIC AND IMAGINATION


The nature of science

Science is a Blend of Logic and Imagination

Scientific knowledge involves human imagination, creativity, and inference.

Much of the scientific enterprise is governed by the ability and creativity of scientists to visualize different situations and predict outcomes.


Durable

SCIENTIFIC KNOWLEDGE IS

DURABLE


The nature of science

Scientific Knowledge is Durable

Scientific ideas are continually tested.

Ideas that are able to withstand the scrutiny of the scientific community form the foundations of our current understandings of the natural world and how it functions.


The nature of science

Theories and laws.

Theories and laws are two different types of knowledge used by scientists to describe natural phenomena. They are equal in terms of scientific validity.

Theories are generally used to explain complex natural processes not easily quantifiable.

Laws use mathematical formulas to show relationships and make predictions about the natural world.


Subject to change

SCIENTIFIC KNOWLEDGE IS

SUBJECT TO CHANGE


The nature of science

Scientific Ideas are Subject to Change

The drive to elucidate the finer points of a commonly held scientific paradigm is what “normal science” is all about.

The sensitive instruments developed to elucidate the finer points of a paradigm help to uncover ambiguities in the expected data. These may lead to changes in our understanding.

Although subject to gradual refinement, “the main body of scientific knowledge is very stable and grows by being corrected slowly and having its boundaries extended gradually.”


The nature of science

SCIENTISTS ATTEMPT TO AVOID

BIAS


The nature of science

Scientists Try to Identify and Avoid Bias

Since scientists within the same field tend to share common methodologies and views, their objectivity must continually be challenged to ensure validity of results.

Within the scientific community there are ethical practices that strive to guarantee scientific endeavors are carried out under universally accepted standards around the world.


Social activity

SCIENCE IS A COMPLEX

SOCIAL ACTIVITY


The nature of science

Science is a Complex Social Activity

Scientific knowledge is tied to social and cultural factors.

Scientific research is dependent upon financial support, and this can influence - both positively and negatively - which areas are investigated.
