A controlled experiment is one in which
a. the experiment is repeated many times to ensure that the results are accurate.
b. the experiment proceeds at a slow pace to guarantee that the scientist can
carefully observe all reactions and process all experimental data.
c. there are at least two groups, one of which does not receive the experimental
treatment.
d. there are at least two groups, one differing from the other by two or more
variables.
e. there is one group for which the scientist controls all variables. - ANSWERthere
are at least two groups, one of which does not receive the experimental treatment.
Why is it important that an experiment include a control group?
, a. The control group is the group that the researcher is in control of; it is the group in
which the researcher predetermines the nature of the results.
b. The control group provides a reserve of experimental subjects.
c. A control group is required for the development of an "if, then" statement.
d. A control group assures that an experiment will be repeatable.
e. Without a control group, there is no basis for knowing if a particular result is due to
the variable being tested or to some other factor. - ANSWERWithout a control group,
there is no basis for knowing if a particular result is due to the variable being tested
or to some other factor.
What is a hypothesis?
a. the same thing as an unproven theory
b. a tentative explanation that can be tested and is falsifiable
c. a verifiable observation sensed directly, or sensed indirectly with the aid of
scientific instrumentation
d. a fact based on qualitative data that is testable
e. a fact based on quantitative data that is falsifiable - ANSWERa tentative
explanation that can be tested and is falsifiable
Discovery science has contributed much to our understanding of nature without most
of the steps of the so-called scientific method.
a. True
b. False - ANSWERTrue
Which of the following best describes the relationship between the atoms described
below? Atom 1 = 31/15 P Atom 2 = 32/15 P
a. They contain 31 and 32 electrons, respectively
b. They are both phosphorus cations
c. They are both phosphorus anions
d. They are both isotopes of phosphorus
e. They contain 31 and 32 protons, respectively - ANSWERThey are both isotopes of
phosphorus
Different atomic forms of an element contain the same number of protons but a
different number of neutrons. What are these different atomic forms called?
a. ions
b. isotopes
c. neutronic atoms
d. isomers
e. radioactive atoms - ANSWERisotopes
In hypothesis-based science, deductive reasoning is used to predict a result that
would be found if a particular hypothesis is correct.
