If you change more than one variable at a time, you will not be able to tell which variable is responsible for what change. Scientists need to know exactly which variable caused the observed experimental results.
It is important to only change one variable at a time when doing an experiment, because if you change more than one, there will be uncertainty as to which one affected the result.
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.
because in certain experiments you need an accurate independent variable so your conulsion could be accurate
Actually, you have two - dependent and independent. But, you only have one variable because otherwise the answer wouldn't be accurate if you had more than one variable.
if you change more than one variable, you will not know which one has had an effect on the experiment. If the outcome changes when one variable is altered, then the change can only be due to the one variable, by logical deduction.

its important to have a manipulative variable so you have at least one variable that will reapond to what you do to it
It is important to only change one variable at a time when doing an experiment, because if you change more than one, there will be uncertainty as to which one affected the result.
a controlled experiment
The term for an experiment in which only one variable is changed at a time is called a controlled experiment. This allows researchers to isolate the effect of that specific variable on the outcome of the experiment.
Because if you change more than one variable at a time, you can't tell which is affecting the results.
A single-variable experiment, also known as a one-factor experiment, is one in which only one variable is manipulated at a time while keeping all other variables constant. This allows researchers to isolate the effects of that specific variable on the outcome of the experiment.
Well in the case that it does have a variable, even just one, it would still be a variable experiment because that one part of the experiment may still cause a different effect/result when changed!!!
Controlled experiment
If you change more that one variable in an experiment, then when the result occurs, you won't know which variable caused the change.
