we don't have control over everything
The factor that changes in a controlled experiment is called the independent variable.
The controlled parts of a controlled experiment are the variables that are kept constant or unchanged throughout the course of the experiment. These include factors such as temperature, time, lighting, and any other conditions that could potentially affect the outcome of the experiment. Controlling these variables helps to ensure that any changes observed in the experiment are a result of the manipulated variable being tested.
A factor being measured in a controlled experiment is a variable that is deliberately changed or manipulated by the experimenter to see how it affects the outcome of the experiment. Factors are typically independent variables that are controlled to observe their impact on the dependent variable being measured.
An experimental group is the group in an experiment that receives some type of treatment. The control group in an experiment receives no treatment. And, in conclusion, sometimes it might not work so be careful!!! :)
An experiment is considered controlled when all variables are kept constant except for the one being tested. This allows researchers to isolate the effect of that specific variable on the outcome of the experiment. Controlled experiments help establish cause-and-effect relationships between variables.
the reason it is important to controll the variables in an experiment is because if the variables are not controlled in an experiment it will be impossible to reproduce the experiment. which also will make it impossible to prove the theory being tested
The hypothesis states what question you are studying. If there is no hypothesis, one wouldn't know what one is studying, so it's impossible to construct a controlled experiment.
controlled experiment
sometimes it is because you might not know what is going to happen.
you might not get the experiment correct (:

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.
Variables
A controlled experiment is better than a none controlled experiment because you can control one of them and the other you can't. Science is a really fun subject.
The reason they would is because it is a lot safer.
