All variables except one, the experimental variable, are kept constant in an experiment.
An experiment of any kind can have infinitely many variables. A controlled experiment can have just as many, provided that all but one are kept exactly the same.
An experiment involves three types of variable.The independent variable is the one you are investigating. It is the one which you deliberately vary in the experiment. You should only have one independent variable.The dependent variable is the variable which you measure to get your results. Often there is only a single dependent variable but there can be more.All other variables must be controlled ie kept constant so they do not change the result. There are usually many control variables in an experiment.
Many conditions that are kept the same in an experiment are known as controlled variables. These can include factors such as temperature, humidity, light levels, and the type of materials used. By keeping these conditions constant, researchers can ensure that any observed changes in the dependent variable are due to manipulation of the independent variable, thereby increasing the validity of the experiment. This helps to eliminate confounding variables that could otherwise affect the results.
Ideally, an experiment should test only one variable (the independent variable) at a time. If you have two or more variables changing at the same time you have no way of knowing which variable is causing your results.
Constants are the things that are kept the same each time one of the trials in the experiment is repeated. For example, constants could include the amount of water used, the brand of effervescent tablet used, the type of water used, and the fact that the water was not stirred. As many outside factors as possible should be kept constant in an experiment so that the researcher can be sure that any changes that occur do so because of the independent variable.

A variable, you can have many variables but you also have 1 constant without a constant you don't know if any thing has changed.

There can only be one independent and one dependent variable. All other variables should be classed as control variables and must be kept constant to achieve a fair test.
The three scientific variables are independent variables, dependent variables, and controlled variables. The independent variable is the variable that is manipulated or changed by the researcher. The dependent variable is the variable that is measured or observed in response to the changes in the independent variable. Controlled variables are the factors that are kept constant to ensure that they do not influence the relationship between the independent and dependent variables.
