I dont know which is the dependent variable, independent variable, or control in this experiment?

my hypothesis is can the amount of alcohol effect the way these mouth washes work?(listerine, scope, crest) and the amount of alcohol in each mouth wash. what is the dependent variable which is the independent variable and which is the control?





AND PLEASE HURRY I HAVE TO WRITE AN ESSAY DUE TOMORROW!!!PLZ HURRY;0I dont know which is the dependent variable, independent variable, or control in this experiment?
Another name for the independent variable is the Manipulated Variable - that is the variable the scientists are changing on purpose - in this case it would be the amount of alcohol contained in the different types of mouthwash.





Another name for the dependent variable is the Measured Variable - in this case the way the mouth washes ';work.'; Here is where I think you have a flaw in your design - how can you MEASURE the way mouthwash works? You need to consider this point carefully.





Finally, the controlled variables are all of the conditions you would keep the same in each trial - for example the amount of mouthwash used for each test, and the amount of time you wait for each mouthwash to ';work'; (whatever that means).





Good luck!I dont know which is the dependent variable, independent variable, or control in this experiment?
the independent varible is the varible that is changed (the mouth washes) and the dependent is the varible thats mesured (the amount of alcohol) the control would be a mouthwashing with just water...no variability or change..nothing to measure...hence its a control
