10/7 Quiz2_Experiment Variables - Mastery - Patrick Mazza | Library

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.

Which definition describes a control variable.

Which definition describes an independent variable.

Which definition describes a dependent variable.

Goal - I can recognize a scientific hypothesis, Independent, Dependent, and Control variables given an experiment.

Select all the things that can changed in this experiment below. Remember to select ALL that apply.
Experiment: Marshmallows are launched at different angles from a slingshot device. The horizontal distance travelled by each marshmallow is recorded.

Identify the independent variable in the experiment below.
