4. experiment
5. conclusion
observation - correct-answer -act of viewing the world around us
question - correct-answer -made based off of an observation
hypothesis - correct-answer -a tentative explanation for an observation
controlled experiment - correct-answer -- test several groups
- introduce a single variable per treatment
- keep conditions as similar as possible from one group to the next
,2|Page
conclusion - correct-answer -supports/refutes hypothesis
- more experimentation needed if refuted
prediction - correct-answer -a guess of what might happen based on observation--
the outcome you would observe if your hypothesis was supported
theory - correct-answer -a sound explanation of the world supported through
continued observation and experiments over a long period of time

variable - correct-answer -feature of an experiment that is changed from one
treatment to the next
test group - correct-answer -exposed to variable in an experiment
, 3|Page
control group - correct-answer -not exposed to the variable in an experiment
importance of test group & control group - correct-answer -they allow researchers
to determine whether the variable in an experiment has an effect
independent variable - correct-answer -manipulation performed on the test group
(ex. hours of tutoring)
