Key Terms
-Scientific Hypothesis: A specific and testable prediction about the results of an experiment.
-Variable: An element, feature, or factor that can vary or change (i.e. boat width, foot length, etc.)
-Dependent Variable: A variable whose ability to change depends on another variable and is measured.
-Independent Variable: A value not dependent on another value but directly changed by an experimenter.
-Control Variable: A variable that is kept the same throughout an experiment to avoid affecting the results.
*Scientific experiments can have many control variables but only one variable can be directly changed (independent)
and for simplicity we will allow only one measured variable (dependent). All other variables should be controlled.
