WGU C165 INTEGRATED PHYSICAL
SCIENCE EXAM SCRIPT COMPLETE
QUESTIONS AND ANSWERS GRADED A+
●● Chemistry
Answer: The study of atoms and molecules, their structures, and their
interactions to form substances
●● Earth science
Answer: The study of the Earth's structure and composition, and
processes that change Earth
●● variables
Answer: The changing quantities in an experiment
●● independent variable
Answer: What you change in an experiment on purpose
●● dependent variable
Answer: The variable that changes because of an independent variable
●● control variable
,Answer: The variable(s) you don't want to study, need to be either
eliminated or kept constant
●● observational study
Answer: When systems are observed as they appear in nature,
researchers do not attempt to change them
●● physical model
Answer: A model of a physical phenomenon, such as a planetary system
●● conceptual model
Answer: A model used to visualize things that cannot be seen, such as
atoms
●● mathematical model
Answer: A model that treats physical objects/phenomena using
mathematical methods
●● computer model
Answer: A detailed, complex model calculated by a computer
●● principle of falsification
,Answer: Principle that only falsifiable statements can be subject to
scientific inquiry
●● hypothesis
Answer: A testable statement about how something in nature works
●● law
Answer: A concise statement that is supported by scientific evidence and
repeated experiments, describes a widespread pattern in nature (what)
●● theory
Answer: A statement that explains a wide range of observations,
supported by a large body of scientific evidence (how/why)
●● Field study
Answer: bservational studies done outside a laboratory setting. Scientists
performing field studies often collect data by observing, without
changing or manipulating the system
●● laboratory study
Answer: researchers study the system of interest in a highly controlled,
artificial setting
●● observation
, Answer:
●● evidence
Answer:
●● data
Answer:
●● big bang theory
Answer: describes how the universe developed, starting from about 0.01
seconds after it began (which astronomers think, based on astronomical
observations and calculations, was roughly 13.8 billion years ago)
●● plate tectonics
Answer: tates that Earth's outermost layer, the lithosphere, is broken up
into many large pieces called tectonic plates
●● atomic theory
Answer: matter is composed of atoms, and that elements are composed
of only one kind of atom
●● meter
Answer: Base unit of length
