INTEGRATED PHYSICAL SCIENCES | QUESTIONS AND
ANSWERS | GRADE A | 100% CORRECT (VERIFIED
SOLUTION) - WGU
Chemistry .....ANSWER.....focuses on the study of atoms and
molecules, their structures, and their interactions to form various
substances.
physics .....ANSWER.....is the study of forces and energy. The
forces that are studied by physicists govern everything from
sound waves to planetary orbits.
Earth science .....ANSWER.....this field focuses on Earth's structure
and composition, as well as the processes that change Earth, such
,Page 2 of 75
as volcanic and seismic activity. Modern Earth science also
includes the studies of other planets.
physical science .....ANSWER.....involve the study of non-living
systems, as opposed to life science (e.g., biology), which is the
study of living systems.
astronomy .....ANSWER.....the branch of science which deals with
celestial objects, space, and the physical universe as a whole.
controlled experiment .....ANSWER.....Scientists perform a
controlled experiment when they want to find out how changing
one thing causes something else to change.
variables .....ANSWER.....In an experiment changing quantities
are called:
independent variable .....ANSWER.....It's what you change on
purpose
,Page 3 of 75
dependent variable .....ANSWER.....is the one that changes
because of the independent variable
control variable .....ANSWER.....The variables that scientists do
not wish to study need to be either eliminated or kept constant
observational study .....ANSWER.....Scientific observations can be
done with our own senses (sight, hearing, smell, taste, or touch) or
by using tools (telescopes, radiation detectors, multimeters, etc.).
The systems are observed as hey appear and researchers do not
attempt to change them.
laboratory experiment .....ANSWER.....researchers study the
system of interest in a highly controlled, artificial setting.
physical model .....ANSWER.....is a model that can be touched.
conceptual model .....ANSWER.....can be used to visualize things
that cannot be seen, such as atoms
, Page 4 of 75
mathematical model .....ANSWER.....treat physical objects or
phenomena using mathematical methods. In these models,
pertinent physical characteristics are represented using formulas,
graphs, or other mathematical means. For example, the
mathematical model below models the wavelength and
amplitude of a wave.
computer model .....ANSWER.....are becoming increasingly
important in explaining and predicting natural phenomena, such
as weather patterns and the detailed movements of objects in
the solar system
principle of falsification .....ANSWER.....is that only falsifiable
statements can be subject to scientific inquiry. A statement such as
"a rock falls because invisible demons pull it down" is not
falsifiable, because no conceivable experiment or observation
could prove that invisible demons are not pulling it.
