In a controlled experiment, there is typically one independent variable. This is the variable that researchers manipulate to observe its effect on the dependent variable. Keeping all other variables constant allows for a clear understanding of the relationship between the independent and dependent variables. However, some experiments may include multiple independent variables, but each one must be tested in a controlled manner.
A controlled experiment means that you try to keep all the variables that are involved in the experiment under control apart from the Dependent and the Independent variables to make sure that any results obtained from the experiment have been affected by the independent variable and not some other extraneous variable. It also ensures that the experiment would have high validity. That is, if the experiment has really measured what it was supposed to measure.
A science project that has variables can be an experiment that aquires for variable change.
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.
A controlled experiment compares results through various methods. Some being a graph, an average, a diagram... etc.
Some controlled variables when using a lemon for an experiment could be its size, ripeness, temperature, and the method of extraction of the lemon juice. These variables should be kept constant throughout the experiment to ensure that any changes observed are due to the manipulated independent variable and not these controlled variables.
Controlled variables are things that may effect the outcome of an experiment, like temperature are pressure or the amount of some substance used. Dependent variables are those which change due to the conditions mentioned above. These might be speed of the reaction, or the quantity of some product.

A variable in an experiment can be manipulated by changing some aspect of the experiment.
In order to conclusively prove or disprove something. i.e an uncontrolled experiment will have so many variables that nothing can be conclusively proven from it, since it could be argued that the outcome could have been caused by any of the uncontrolled variables. Whereas by controlling some of the variables, the ability to prove that one variable links to a certain outcome is easier to establish.

Some independent variables for a balloon-powered car experiment could include the size of the balloon, the amount of air blown into the balloon, the weight of the car, and the surface the car is tested on. These variables can be changed or controlled by the experimenter to observe their effects on the car's performance.

Independent variables are variables that can be changed in an experiment, while dependent variables are variables that change as a result of an experiment. In other words, independent variables are what you change, and dependent variables are the results of the experiment.
list some variables that can change in an experiment?
They are called "variables", and there are three forms.The dependent variable is the result of the experiment or function.The independent variable is the one that is deliberately changed to observe the effect on the dependent variable.The controlled variables should be maintained constant during the experiment so as not to influence the result.
