AND CORRECT DETAILED ANSWERS|
Physical Science: - ANSWER-The scientific study of nonliving matter. Ex: chemistry, physics, and
Earth science.
Astronomy: - ANSWER-The study of the moon, stars, and other objects in space.
Controlled Experiment: - ANSWER-An experiment in which only one variable is manipulated at a
time..
Independent Variable: - ANSWER-The variable that is manipulated in an experiment.
Chemistry: - ANSWER-The study of atoms and molecules, their structures, and their interactions
to form various substances.
Physics: - ANSWER-The study of forces, energy and motion.
Earth Science: - ANSWER-This field focuses on Earth's structure and composition, as well as the
processes that change Earth, such as volcanic and seismic activity.
Dependent Variable: - ANSWER-The outcome factor; the variable that may change in response
to manipulations of the independent variable.
Control Variable: - ANSWER-A variable that is kept constant during a controlled experiment.

Observational Study: - ANSWER-The systems are observed as they appear in nature and
researchers do not attempt to change them.
Laboratory Experiment: - ANSWER-Researchers study the system of interest in a highly
controlled artificial setting (lab).
Physical Model: - ANSWER-A physical representation of an object. Ex: Scaled down version of
the solar system.
Conceptual Model: - ANSWER-A verbal or graphical explanation for how a system works or is
organized. Ex: posters, charts.
Mathematical Model: - 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: - 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: - ANSWER-Principle that only falsifiable statements can be subject to
scientific inquiry.
Hypothesis: - ANSWER-A testable prediction, often implied by a theory.
Theory: - ANSWER-A hypothesis that has been tested with a significant amount of data.
Law: - 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: - ANSWER-Scientists test their ideas with a variety of different types of
investigations. Ex: laboratories, controlled experiments, astronomy, field studies, models.
SI System: - ANSWER-International System of units based on the metric system and units
derived from the metric system.
Base Quantities: -
Time: - ANSWER-Base quantity that measures how long an event lasts or the break between
events. ANSWER-Seven designated physical quantities (sets) from which all other SI quantities
can be derived.
(1) Meter (m)-length
(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
Length: - ANSWER-Used to describe the distance between two objects, or the two ends of an
object.
Mass: - ANSWER-Used to describe the amount of matter in an object.
Temperature: - ANSWER-A measure of how hot or cold something is.
Gram: - ANSWER-a metric unit of mass equal to one thousandth of a kilogram.
