with 100% correct answers
Chemistry - answer the study of the composition,
structure, and properties of matter and the
changes it undergoes
Scientific Method - answer set of general
procedures based on experimentation and
observation used to acquire scientific knowledge
and explain natural phenomena
Hypothesis - answer model or statement that can
be tested by experiment, offers an explanation for
a scientific law

something we see, hear, smell, taste, or feel
Scientific Fact - answer is a reproducible piece of
data about some natural phenomenon that is
obtained from experimentation
, Scientific Law - answer generalization that
summarizes scientific facts about a natural
phenomenon
Scientific Theory - answer scientific hypothesis
that has been tested and validated over a long
period of time
Exact Number - answer number that has a value
with no uncertainty in it, known exactly
Inexact Number - answer number that has a value
with a degree of uncertainty in it
Precision - answer indicator of how close a series
of measurements on the sam object are to each
other
