Pure Science vs. Technology

Pure science

Technology


Continue to search for
scientific knowledge


Ex: scientist developing super
conductors looks at the
materials used to make them


Application of science


Ways to use knowledge from
pure science


Ex: using superconductors to
to

build high
-
speed
computers

5.

Scientific Law vs. Scientific Theory

Scientific Law

Scientific Theory


Summary of an
observed
natural event


Does not necessarily explain
why or how, just tells you
WHAT

will happen


Serves as basis for scientific
principles


Ex: Law of gravity


Ex: Laws of motion F= ma


Theories are used to explain a
law


Much more than a guess!


Tries to explain WHY or HOW


Explanation that has been
tested and proven
many

times
(evidence that supports it)


Valid as long as no evidence
disputes it


Ex: Atomic Theory

Sometimes theories or laws have to be
changed or replaced when new
discoveries are made.

6. Scientific Models


Represents an object or event so that it can be studied
to understand the
real
object or event.

Examples:


Drawings


Computer models (weatherman)


Mathematical


Simulators
