100 QUESTIONS AND CORRECT DETAILED
ANSWERS WITH RATIONALES VERIFIED
ALREADY GRADED EXAMINATION TEST
⩥ physics. Answer: is the study of forces and energy. The forces that are
studied by physicists govern everything from sound waves to planetary
orbits.
⩥ 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. Modern Earth science also includes the studies of
other planets.
⩥ physical science. Answer: involve the study of non-living systems, as
opposed to life science (e.g., biology), which is the study of living
systems.
⩥ astronomy. Answer: the branch of science which deals with celestial
objects, space, and the physical universe as a whole.
⩥ controlled experiment. Answer: Scientists perform a controlled
experiment when they want to find out how changing one thing causes
something else to change.
,⩥ variables. Answer: In an experiment changing quantities are called:
⩥ independent variable. Answer: It's what you change on purpose
⩥ dependent variable. Answer: is the one that changes because of the
independent variable
⩥ control variable. Answer: The variables that scientists do not wish to
study need to be either eliminated or kept constant
⩥ observational study. Answer: Scientific observations can be done with
our own senses (sight, hearing, smell, taste, or touch) or by using tools
(telescopes, radiation detectors, multimeters, etc.). The systems are
observed as hey appear and researchers do not attempt to change them.
⩥ laboratory experiment. Answer: researchers study the system of
interest in a highly controlled, artificial setting.
⩥ physical model. Answer: is a model that can be touched.
⩥ conceptual model. Answer: can be used to visualize things that cannot
be seen, such as atoms
, ⩥ mathematical model. Answer: treat physical objects or phenomena
using mathematical methods. In these models, pertinent physical
characteristics are represented using formulas, graphs, or other
mathematical means. For example, the mathematical model below
models the wavelength and amplitude of a wave.
⩥ computer model. Answer: are becoming increasingly important in
explaining and predicting natural phenomena, such as weather patterns
and the detailed movements of objects in the solar system
⩥ principle of falsification. Answer: is that only falsifiable statements
can be subject to scientific inquiry. A statement such as "a rock falls
because invisible demons pull it down" is not falsifiable, because no
conceivable experiment or observation could prove that invisible
demons are not pulling it.
⩥ Hypothesis. Answer: is a testable statement about how something in
nature works. It is typically the best tentative assumption that
researchers can make based on the evidence they already have at that
point.
⩥ Theory. Answer: is a statement that explains a wide range of
observations and that is supported by a large body of scientific evidence.
It explains how and why things happen
