WGU C165 Integrated Physical Science
Questions and Answers Already Passed
physics ✔✔the study of forces, energy, motion
Chemistry ✔✔study of atoms and molecules, their structures, and their interactions to form various
substances.
Earth Science ✔✔Earth's structure and composition, as well as the processes that change Earth,
such as volcanic and seismic activity.
astronomy ✔✔The study of the moon, stars, and other objects in space
Science ✔✔An organized way of gathering and analyzing evidence about the natural world.
Precision ✔✔a measure of how close a series of measurements are to one another
SI ✔✔is a scientific method of expressing the magnitudes or quantities of important natural
phenomena. There are seven base units in the system, from which other units are derived. Universal
for comparing data.
physical science ✔✔the sciences concerned with the study of inanimate natural objects, including
physics, chemistry, astronomy, and related subjects.
life science ✔✔the study of living things
controlled experiment ✔✔An experiment in which only one variable is manipulated at a time. Or
a condition that is being held constant
independent variable ✔✔what is being changed
dependent variable ✔✔what is being measured
control ✔✔In an experiment, the standard that is used for comparison
Observational experiment or study ✔✔studies attempt to understand cause-and-effect
relationships. However, unlike experiments, the researcher is not able to control (1) how subjects
are assigned to groups and/or (2) which treatments each group receives. ... Therefore, a sample
survey is an example of an observational study.
field study ✔✔a research investigation carried out in a naturally occurring setting
laboratory study ✔✔Research done in a laboratory
Physical Model ✔✔A physical representation of an object. Prototypes and appearance models are
physical models.
conceptual model ✔✔a verbal or graphical explanation for how a system works or is organized
mathematical model ✔✔one or more equations that represent the way a system or process works
Hypothesis ✔✔A testable prediction, often implied by a theory
Theory ✔✔A hypothesis that has been tested with a significant amount of data. Explains why
something happened.
Law ✔✔A law in science is a generalized rule to explain a body of observations in the form of a
verbal or mathematical statement. Scientific laws (also known as natural laws) imply a cause and
