Scientific Inquiry and Engineering
Design Processes Study Review Test.

scientific inquiry - CORRECT ANSWER A process used by scientists to find answers to a question or to
solve a problem.



hypothesis - CORRECT ANSWER a prediction or a possible explanation to the question or problem which
can be tested in an experiment.



controlled experiment - CORRECT ANSWER An experiment in which only one variable is changed at a
time. All other variables should be unchanged or "controlled".



independent variable (IV) - CORRECT ANSWER the variable that is purposely changed (or tested) by the
experimenter. Only one of these variables should be changed at a time.



dependent variable (DV) - CORRECT ANSWER The variable that changes as a result of the independent
variable. What you observe, measure, and record during the experiment (data)



control - CORRECT ANSWER Serves as the comparison. It is the same as the experimental group, except
that the one variable (IV) that is being tested is removed.



conclusion - CORRECT ANSWER A statement that sums up what you learned from an experiment and
states if the hypothesis is proven or dis-proven.



data - CORRECT ANSWER the information or observations gathered during an experiment



constants (control variables) - CORRECT ANSWER the variables in an experiment that are kept the same



problem or question - CORRECT ANSWER The first step in the scientific or engineering process is to
identify this. It must be testable.
