WGU C165 INTEGRATED PHYSICAL SCIENCE
EXAM SCRIPT 2026 COMPLETE QUESTIONS
AND SOLUTIONS 100% CORRECT
◉ 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
(7) Moles (mol)-amount of substance
◉ Time: Answer: Base quantity that measures how long an event lasts or
the break between events.
◉ Length: Answer: Used to describe the distance between two objects,
or the two ends of an object.
◉ Mass: Answer: Used to describe the amount of matter in an object.
◉ Temperature: Answer: A measure of how hot or cold something is.
◉ Gram: Answer: a metric unit of mass equal to one thousandth of a
kilogram.
◉ Meter: Answer: The base unit of length in the metric system. Unit
symbol (m).
