Question: 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;0

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!

Your independent variable would be what the mothers eat for that one month and your dependent variable would be what happens when the child drinks the carrot juice. Independent: What the mothers eat for that 1 month Dependent: More or less tolerance for the child Controlled Variable: ( the thing you didn't change) the gender of the child, the same type of carrot juice, the same type of water, the same length of time she nursed her child Hope this helps!

The hypothesis is the question you are attempting to test.. in this case it might be "grass grows just as well with salt water as with fresh" growing grass with fresh water is considered 'normal' so that is the control group... the unchanged situation... the grass grown with salt water is called the treatement group the independent variable is the thing you control, in this case whether the grass is treated with fresh or salt water... I would assume the dependent variable is the length of the grass after some given amount of time or possibly just whether or not grass grew at all... in any case the dependent variable is the thing that happens as a result of your control of the independent variable If grass grows in both cases, you could measure several stalks of grass at various times and graph growth rates over time... seems to me that grass probably won't grow at all in salt water

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
