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.
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.
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).

Sir Isaac Newton discovered that the force of gravity between two masses
increases if the masses increase, and decreases if the distance between the masses
increases. No experiments have ever contradicted this relationship.
