What is a variable in a experiment
a controlled experiment is when you keep everything the same besides one thing. the one "thing" you change is called a munipulated variable.
It depends on the experiment or the category. you welcome s.a No it's the variable k.a.
The chemical composition and physical state of substances can change during an experiment.For example two reactants in solid or liquid form can react in an experiment to give a product in a gaseous form.
In an experiment there is one thing that it is compared with experimental data. This is when the end results.The experiment data is compared to one thing. It is compared to the end results.

Because if you change more than one thing at the same time, you can't say which one caused a change in the result.
it is the one thing that stays the same in an experiment

In a controlled experiment, the control variable is the one specific thing that is kept constant to measure the change of the other variables. Those variables are the parameters that are being tested.
If you change more that one variable in an experiment, then when the result occurs, you won't know which variable caused the change.
Um... try constants. ;)Constants are factors in the experiment that remain, well, constant. For example, if you have two cells in two petri dishes and you put salt in one of them, for whatever reason. Variable, the thing you change, is the salt. The constants are things like temperature, breeze, etc.
actually wanting to do a science fair experiment?
