WGU C165 INTEGRATED PHYSICAL
SCIENCE ACTUAL EXAM QUESTIONS AND
CORRECT ANSWERS COMPLETE STUDY
GUIDE
●● Physics:
Answer: The study of forces, energy and motion.
●● Earth Science:
Answer: This field focuses on Earth's structure and composition, as well
as the processes that change Earth, such as volcanic and seismic activity.
●● Physical Science:
Answer: The scientific study of nonliving matter. Ex: chemistry, physics,
and Earth science.
●● Astronomy:
Answer: The study of the moon, stars, and other objects in space.
●● Controlled Experiment:
Answer: An experiment in which only one variable is manipulated at a
time..
,●● Independent Variable:
Answer: The variable that is manipulated in an experiment.
●● Dependent Variable:
Answer: The outcome factor; the variable that may change in response
to manipulations of the independent variable.
●● Control Variable:
Answer: A variable that is kept constant during a controlled experiment.
●● Observational Study:
Answer: The systems are observed as they appear in nature and
researchers do not attempt to change them.
●● Laboratory Experiment:
Answer: Researchers study the system of interest in a highly controlled
artificial setting (lab).
●● Physical Model:
Answer: A physical representation of an object. Ex: Scaled down version
of the solar system.
,●● Conceptual Model:
Answer: A verbal or graphical explanation for how a system works or is
organized. Ex: posters, charts.
●● Mathematical Model:
Answer: Uses different forms of data to represent the way a system or
process works. Ex: formulas, graphs, mathematical means. Ex: F=ma
(formula).
●● Computer Model:
Answer: A computer program that models an event or object. Important
in explaining and predicting natural phenomena. Ex: weather patterns,
solar system.
●● Principle of Falsification:
Answer: Principle that only falsifiable statements can be subject to
scientific inquiry.
●● Hypothesis:
Answer: A testable prediction, often implied by a theory.
●● Theory:
Answer: A hypothesis that has been tested with a significant amount of
data.
, ●● Law:
Answer: A concise statement that is supported by scientific evidence and
repeated experiments. Describes a widespread pattern in nature.
Intended to be universal.
●● Scientific Investigation:
Answer: Scientists test their ideas with a variety of different types of
investigations. Ex: laboratories, controlled experiments, astronomy, field
studies, models.
●● SI System:
Answer: International System of units based on the metric system and
units derived from the metric system.
●● Base Quantities:
Answer: Seven designated physical quantities (sets) from which all other
SI quantities can be derived.
(1) Meter (m)-length
(2) Kilogram (k)-mass
(3) Second (s)-time
(4) Kelvin (K)-temperature
(5) Amperes (A)-"amp"-electric current
(6) Candela (cd)-light intensity
