PHYSICAL SCIENCES OA Exam
Questions and Answers Graded A+
Chemistry: - Correct answer-The study of atoms and molecules, their structures,
and their interactions to form various substances.
Physics: - Correct answer-The study of forces, energy and motion.
Earth Science: - Correct answer-This field focuses on Earth's structure and
composition, as well as the processes that change Earth, such as volcanic and
seismic activity.
Physical Science: - Correct answer-The scientific study of nonliving matter. Ex:
chemistry, physics, and Earth science.
Astronomy: - Correct answer-The study of the moon, stars, and other objects in
space.
Controlled Experiment: - Correct answer-An experiment in which only one
variable is manipulated at a time..

,Independent Variable: - Correct answer-The variable that is manipulated in an
experiment.
Dependent Variable: - Correct answer-The outcome factor; the variable that may
change in response to manipulations of the independent variable.
Control Variable: - Correct answer-A variable that is kept constant during a
controlled experiment.
Observational Study: - Correct answer-The systems are observed as they appear in
nature and researchers do not attempt to change them.
Laboratory Experiment: - Correct answer-Researchers study the system of interest
in a highly controlled artificial setting (lab).
Physical Model: - Correct answer-A physical representation of an object. Ex:
Scaled down version of the solar system.
Conceptual Model: - Correct answer-A verbal or graphical explanation for how a
system works or is organized. Ex: posters, charts.
Mathematical Model: - Correct answer-Uses different forms of data to represent
the way a system or process works. Ex: formulas, graphs, mathematical means. Ex:
F=ma (formula).

,Computer Model: - Correct answer-A computer program that models an event or
object. Important in explaining and predicting natural phenomena. Ex: weather
patterns, solar system.
Principle of Falsification: - Correct answer-Principle that only falsifiable
statements can be subject to scientific inquiry.
Hypothesis: - Correct answer-A testable prediction, often implied by a theory.
Theory: - Correct answer-A hypothesis that has been tested with a significant
amount of data.
Law: - Correct answer-A concise statement that is supported by scientific evidence
and repeated experiments. Describes a widespread pattern in nature. Intended to be
universal.
Scientific Investigation: - Correct answer-Scientists test their ideas with a variety
of different types of investigations. Ex: laboratories, controlled experiments,
astronomy, field studies, models.
SI System: - Correct answer-International System of units based on the metric
system and units derived from the metric system.
Base Quantities: - Correct answer-Seven designated physical quantities (sets) from
which all other SI quantities can be derived.

(2) Kilogram (k)-mass
(3) Second (s)-time
(4) Kelvin (K)-temperature
(5) Amperes (A)-"amp"-electric current
(6) Candela (cd)-light intensity
(7) Moles (mol)-amount of substance
Time: - Correct answer-Base quantity that measures how long an event lasts or the
break between events.
Length: - Correct answer-Used to describe the distance between two objects, or the
two ends of an object.
Mass: - Correct answer-Used to describe the amount of matter in an object.
Temperature: - Correct answer-A measure of how hot or cold something is.
Gram: - Correct answer-a metric unit of mass equal to one thousandth of a
kilogram.
Meter: - Correct answer-The base unit of length in the metric system. Unit symbol
(m).
