Pre_goal - I can tell the difference among the definitions of the dependent variable, independent variable, and the control variable.

Using the definitions below to answer questions #1-3.

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. ramp height, etc.)

-Dependent Variable: A variable whose value 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.

*There can be many control variables but only one variable can be directly changed (independent)

and for simplicity one measured variable (dependent). All other variables must be controlled.

Identify a scientific hypothesis that is being tested in the situation below.
Situation: An experiment was done in which the air temperature of an oven was changed and the affect on the baking time was written down.

Scientific hypothesis: If the size of the oven increases then the baking time will increase.

Scientific hypothesis: If the temperature of the air in the oven increases then the baking time will decrease.

Scientific hypothesis: If the size of the slingshot increases then the distance travelled will increase.
