Why is it important to test only one variable at a time during a science investigation?
If you test only one variable then you know that the difference in the experimental and control setup is that one independent variable. If you test more than one you will not know which one made the difference.
Does the independent or dependent variable change?
The Independent variable is the one you control. The dependent variable is controlled by the Independent Variable.
What does control variable mean in an experiment?
A control variable means an experiment that does not change, and it's used to validate results. For example, one want to test how two plants would grow, one needs to give each plant the same amount of water at the same time.
Definitions of the 3 types of variables in doing an experiment?
The three variable in an experiment are independent, dependent, and controlled. The independent is the variable you control, the dependent is the variable that will change according to the independent. The control is kept constant so they do not affect the dependent.
What dose variable mean in science?
A variable is an element in an experiment that you control. There should only be one variable in an experiment or the results will not be accurate.
What are control groups?
study one variable at a time.
Is time or temperature the independent variable?
it depends the one you wish to control in the experiment , for example if the temperature was measured every minutes so the controlled variable is time...
What is the independent variable time or temperature?
it depends the one you wish to control in the experiment , for example if the temperature was measured every minutes so the controlled variable is time...

The Independent variable is the one you control. The dependent variable is controlled by the Independent Variable.
What are the similarities between a control and a variable?
There are not any similarities between a control and a variable. However, a Control Variable, is a variable.
In any experiment the one factor being tested is the variable control or the data?
It is the variable.
What does it mean to control the variables in an experiment?
Controls are the things you leave the same when you do an experiment. Variables are the things you affect in an experiment to see if it makes a difference. It depends on the experiment how you would "control" the variable.
What dose variable mean in science?
A variable is an element in an experiment that you control. There should only be one variable in an experiment or the results will not be accurate.
What is an experiment with the variable left out?
A control experiment with respect to that variable. There may be several variables and it may be necessary to leave each one of them out in a different control.
Why is it important to control variables except one?
The variable you can't control is presumably the one you want to know. If you know one variable, it could be anything, weight, temperature, mass etc, and you know the result in the experiment, you can work out the missing variable and therefore the result of your experiment.
