Here is a helpful website that has a great example of a controlled experiment:

An experiment has to have a varible, if it doesn't that it's probably and engineering experiment or robotics. I think its called a "control"
Controlled (or control) variables are things that are kept the same during an experiment. There are usually many- for example, when testing how light intensity affects photosynthesis, the controlled variable would be the type of plant used, or the color of the light.
In an experiment, the independent variable is altered, and the effect observed is the dependent variable, or outcome. The controlled variable is intended to be kept the same throughout the experiment so that changes in it do not affect the results.
A controlled variable is the part of an experiment has to remain constant throughout the entire time. Example: Heating a cup of water to dissolve sugar. The temperature would change time to time, but the CONTROLLED variable would have to be the type of sugar and consistency of stirring.
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.
Pretty much having controlled variables. Controlled variables are something in the experiment that must remain the same through all tests. For example, if you are testing the decay of an apple... The temperature that the two fruits are enduring during the experiment must be the exact same.

A controlled experiment is an experiment in which all factors are controlled except for the one variable you will be altering. If you were performing a controlled experiment on the effects of fertilizer on plant growth, for example, you have to control plant variety, exposure to sunlight, soil type and water ration. The only thing you would change is the fertilizer used on each plant.
it depends the one you wish to control in the experiment , for example if the temperature was measured every minutes so the controlled variable is time...
It is an experiment in which only one variable is changed for example if I was seeing where a banana rotted fastest the only variable that would change is where the banana is placed.

An example of an experiment where only one variable is changed is testing the effect of different amounts of sunlight on plant growth. In this experiment, all other factors such as soil quality, water, and temperature are kept constant, while the amount of sunlight received by each plant is varied. This allows researchers to isolate the specific impact of sunlight exposure on plant growth.
In an experiment, the independent variable is altered, and the effect observed is the dependent variable, or outcome. The controlled variable is intended to be kept the same throughout the experiment so that changes in it do not affect the results.
A controlled experiment is different from others since it has the same amount of things except for only one variable. For example of a controlled experiment, If you have two plants and you want to see if it will grown better in sunlight or in darkness. So you put on in the closet and put the other one in a open window. You water and give both of them the same amount of soil, water, ferterizer. Except for the one variable which in this case is sunlight.
It is impossible to perform controlled experiments on phenomena that are unpredictable, uncontrollable, or unethical to manipulate. For example, certain natural disasters, historical events, or intentional harm to individuals cannot be ethically or practically studied through controlled experiments.
