WGU C165 OA EXAM INTEGRATED PHYSICAL
SCIENCES
physics - ANS-the study of forces, energy, motion
Chemistry - ANS-study of atoms and molecules, their structures, and their interactions
to form various substances.
Earth Science - ANS-Earth's structure and composition, as well as the processes that
change Earth, such as volcanic and seismic activity.
astronomy - ANS-The study of the moon, stars, and other objects in space
Science - ANS-An organized way of gathering and analyzing evidence about the natural
world.
Precision - ANS-a measure of how close a series of measurements are to one another
SI - ANS-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 - ANS-the sciences concerned with the study of inanimate natural
objects, including physics, chemistry, astronomy, and related subjects.
life science - ANS-the study of living things
controlled experiment - ANS-An experiment in which only one variable is manipulated at
a time. Or a condition that is being held constant
independent variable - ANS-what is being changed
dependent variable - ANS-what is being measured
control - ANS-In an experiment, the standard that is used for comparison
Observational experiment or study - ANS-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 - ANS-a research investigation carried out in a naturally occurring setting
laboratory study - ANS-Research done in a laboratory
, Physical Model - ANS-A physical representation of an object. Prototypes and
appearance models are physical models.
conceptual model - ANS-a verbal or graphical explanation for how a system works or is
organized
mathematical model - ANS-one or more equations that represent the way a system or
process works
Hypothesis - ANS-A testable prediction, often implied by a theory
Theory - ANS-A hypothesis that has been tested with a significant amount of data.
Explains why something happened.
Law - ANS-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 effect between the observed elements and must always apply
under the same conditions. Explains how it happened not why.
Observation - ANS-Information obtained through the senses.
evidence - ANS-proof
Data - ANS-Facts and statistics collected together for reference or analysis
Big Bang Theory - ANS-Cosmological model that explains the sudden development of
the universe through expansion from a hot, dense state.
plate tectonics - ANS-A theory stating that the earth's surface is broken into plates that
move.
atomic theory - ANS-a theory that states that all matter is composed of tiny particles
called atoms.
gram - ANS-a metric unit of mass equal to one thousandth of a kilogram.
meter - ANS-The meter is the basic unit of length in the SI system of units. ... The
previous definition of the meter was one ten-millionth of the distance from the
geographic north pole to the equator, measured over the earth's surface in a circle
running through Paris, France.
second - ANS-SI base unit for time
Celsius - ANS-Metric unit for measuring temperature; On this scale water freezes at
zero and boils at 100.
