QUESTIONS AND CORRECT DETAILED ANSWERS (WITH
ILLUSTRATED DIAGRAMS)
The study of atoms and
molecules, their struc-
tures, and their interac-
Chemistry: tions to form various sub-
stances.
The study of forces, ener-
gy and motion.
Physics:
This field focuses on
Earth's structure and com-
position, as well as the
Earth Science:
processes that change
Earth, such as volcanic
and seismic activity.
, The scientific study of non-
living matter. Ex: chem-
istry, physics, and Earth
Physical Science: science.
The study of the moon,
Astronomy: stars, and other objects in
space.
An experiment in which
Controlled Experiment: only one variable is manip-
ulated at a time..
, The variable that is manip-
ulated in an experiment.
Independent Variable:
The outcome factor; the
variable that may change
in response to manipula-
tions of the independent
Dependent Variable: variable.
A variable that is kept con-
stant during a controlled
experiment.
Control Variable:
Observational Study:
, The systems are observed
as they appear in nature
and researchers do not at-
tempt to change them.
Researchers study the
system of interest in a
highly controlled artificial
setting (lab).
Laboratory Experiment:
A physical representation
of an object. Ex: Scaled
down version of the solar
system.
Physical Model:
Conceptual Model:
