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