WGU C165 OA EXAM INTEGRATED
PHYSICAL SCIENCES OA EXAM
QUESTION ACTUAL EXAM 100%
VERIFIED
Earth science - The study of the Earth's structure and composition, and processes that
change Earth
Physics - The study of forces, energy, motion
Chemistry - The study of atoms and molecules, their structures, and their interactions to
form substances
essential attributes of science - 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 - The changing quantities in an experiment
independent variable - What you change in an experiment on purpose
dependent variable - The variable that changes because of an independent variable
control variable - The variable(s) you don't want to study, need to be either eliminated or
kept constant
observational study - When systems are observed as they appear in nature,
researchers do not attempt to change them
physical model - A model of a physical phenomenon, such as a planetary system
conceptual model - A model used to visualize things that cannot be seen, such as
atoms
mathematical model - A model that treats physical objects/phenomena using
mathematical methods
computer model - A detailed, complex model calculated by a computer
principle of falsification - Principle that only falsifiable statements can be subject to
scientific inquiry
hypothesis - A testable statement about how something in nature works
law - A concise statement that is supported by scientific evidence and repeated
experiments, describes a widespread pattern in nature (what)
theory - A statement that explains a wide range of observations, supported by a large
body of scientific evidence (how/why)
meter - Base unit of length
kilogram - Base unit of mass
second - Base unit of time
kelvin - Base unit of temperature
Derived units - What is produced when the base units/quantities are combined
