WGU C165 INTEGRATED PHYSICAL
SCIENCES QUESTIONS AND ANSWERS
2025
Physics - correct answer- The study of forces, energy, motion
Chemistry - correct answer- The study of atoms and molecules,
their structures, and their interactions to form substances
Earth science - correct answer- The study of the Earth's
structure and composition, and processes that change Earth
essential attributes of science - correct answer- Studies the
natural world
Uses testable ideas
Relies on data from observations/experiments
Presented for evaluation by other scientists
Leads to further questions/research
variables - correct answer- The changing quantities in an
experiment
,2 | Page
independent variable - correct answer- What you change in an
experiment on purpose
dependent variable - correct answer- The variable that changes
because of an independent variable
control variable - correct answer- The variable(s) you don't want
to study, need to be either eliminated or kept constant
observational study - correct answer- When systems are
observed as they appear in nature, researchers do not attempt
to change them
physical model - correct answer- A model of a physical
phenomenon, such as a planetary system
conceptual model - correct answer- A model used to visualize
things that cannot be seen, such as atoms
, 3 | Page
mathematical model - correct answer- A model that treats
physical objects/phenomena using mathematical methods
computer model - correct answer- A detailed, complex model
calculated by a computer
principle of falsification - correct answer- Principle that only
falsifiable statements can be subject to scientific inquiry
hypothesis - correct answer- A testable statement about how
something in nature works
law - correct answer- A concise statement that is supported by
scientific evidence and repeated experiments, describes a
widespread pattern in nature (what)
theory - correct answer- A statement that explains a wide range
of observations, supported by a large body of scientific
evidence (how/why)
meter - correct answer- Base unit of length
