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.
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.

An independent variable is a factor or condition that is manipulated or changed in an experiment to observe its effect on a dependent variable. It is the variable that researchers control to test its impact, while the dependent variable is measured to see how it responds to changes in the independent variable. For instance, in a study examining the effect of temperature on plant growth, temperature would be the independent variable.
To draw valid conclusions from an experiment, there must be two kinds of conditions observed: 1. An experimental condition (the particular manipulation of a variable being studied), and 2. A control condition (the situation that unfolds without manipulating the variable being studied). Only comparing these two conditions will enable one to know that the factors changed by experiment are what led to the results of the experiment. For example, if you apply heat to water in order to produce steam (an experimental condition), you must also have some water that is not heated (a control condition) so you can be assured that water does not convert to steam simply because time passes without heat. In the social sciences, wherein it is common to study groups of people, the experimental and control conditions may be referred to as separate groups.
haha is this from a school called k12 anyway he was the first to experiment with electricity
Controlled Experiment :Pcontrolled 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.
a controlled experiment
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
Controlled Experiment :Pcontrolled experiment.
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.
An experiment in which only one variable changes is called an "controlled experiment" or "single-variable experiment." In this type of experiment, the researcher manipulates one variable (independent variable) while keeping all other variables constant to determine its effect on the outcome (dependent variable). This approach helps to isolate the impact of that single variable on the results.
a controlled experiment
An experiment with only one independent variable is called a one-way experiment. This means that the effect on the dependent variable is attributed to changes in only one factor. This design helps to determine the specific impact of that variable on the outcome of interest.
A controlled experiment is when only one variable, the manipulated variable, is changed at a time to observe its effect on the dependent variable, while keeping all other variables constant. This approach helps to determine the specific impact of the manipulated variable on the outcome of the experiment.
