ASSESSMENT QUESTIONS AND
ANSWERS
Chemistry: - ANSWERS-The study of atoms
and molecules, their structures, and their
interactions to form various substances.

energy and motion.
Earth Science: - ANSWERS-This field
focuses on Earth's structure and
composition, as well as the processes that
change Earth, such as volcanic and seismic
activity.

moon, stars, and other objects in space.
Controlled Experiment: - ANSWERS-An
experiment in which only one variable is
manipulated at a time..
Independent Variable: - ANSWERS-The
variable that is manipulated in an
experiment.
Dependent Variable: - ANSWERS-The
