An experiment is a simulation of complete or part of a real scenario in a controlled environment. We come to know of various outcomes of an experiment based on the values/degree of the variables in different quantity/quality. Unless the variables are controlled, experiment can go out of hand and sometimes become a real disaster.
To eliminate the possibility of hidden or unknown variables the scientist must a control experiment.
The number of dependent variables in an experiment varies, but there is often more than one. experiments also have controlled variables are quantities that a scientist wants to remain constant, and he must be observe them as carefully as the dependent variables.
Scientists repeat experiments for reliability. The experiment must be repeated for the scientist to develop a theory. One experiment does not prove your hypothesis correct; therefore, it must be done a several times.
A theory is useless if it cannot be tested and verified/disproven. That is the purpose of experiments.
The variables that must remain the same between the control group and experimental group is are called controlled variables, and include everything except the experimental variable.

The scientist must propose an idea and document it with experiments that prove it. The experiments must be repeatable by others and the same result must be obtained by them
If they are supposed to affect the results in the experiment ie. they are what is being tested, they are the test variables. If they must be kept the same to ensure a fair test ie. the scientist is not testing with them, they are called control variables.
Because it helps them know the results of the objects in the experiment and how they differ. This way the scientist knows which succeeded and which failed.
Scientists use technology to conduct experiments, eliminate unwanted variables to increase accuracy, and to measure their results. Without technology, most, if not all, of the experiments scientists engage in would be impossible without technology. Since the purpose of science is to increase technology, technology must be used in experiments in order to improve it.

Variables that must be kept constant in an experiment are known as control variables. These variables are factors that can influence the outcome of the experiment, so keeping them constant ensures that any observed changes are due to the independent variable being tested.
If scientists are to be able to draw meaningful conclusions from their experiments, they must have accurate records. If you do not know exactly what happened, you will not be able to figure out exactly what it means.
Variables that should remain the same in an experiment to have a fair test of the independent variable are called control variables. These include factors such as temperature, time of day, equipment used, and method of measurement. By keeping these control variables constant, any observed effects in the experiment can be confidently attributed to changes in the independent variable.
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.
