To ensure your experiment is fair, you must keep all variables constant except for the one you are testing. This means controlling outside factors that could influence the results of your experiment.
Environmental factors if you cannot control them.Variable factors if you can control them.See link below for easy explanation:In an experiment the scientist is able to change the independent variable. To insure a fair test, a good experiment has only one independent variable. As the scientist changes the independent variable, he or she observes what happens. - See more at: http://www.chacha.com/question/what-part-of-an-experiment-is-the-factor-that-you-change#sthash.iyH25Jac.dpufIn an experiment the scientist is able to change the independent variable.

A constant variable is a variable that remains the same throughout the experiment to ensure fairness and accuracy of the results. It is used as a baseline for comparison with the changing variables being tested.
In a science fair project, the "what" method refers to clearly defining your research question or objective. This involves stating what specific question you are trying to answer or problem you are investigating in your experiment. By clearly articulating the "what" of your project, you can ensure that your research is focused and targeted towards achieving your intended outcome.
An experiment that lacks proper controls or randomization cannot be used as a fair comparison with any other test. Without these essential components, it is difficult to isolate the effect of the independent variable being studied, leading to flawed or biased results.
An experiment in which only one variable changes is called an "controlled experiment" or "single-variable experiment." In this type of experiment, the researcher manipulates one variable (independent variable) while keeping all other variables constant to determine its effect on the outcome (dependent variable). This approach helps to isolate the impact of that single variable on the results.
To ensure an experiment is a fair test in chemistry, you should control all variables except for the one being tested. Use identical conditions for all trials, measure with precision, and replicate the experiment to ensure reliability. Randomize sample selection and use a control group for comparison.
A fair experiment is fair wheras an accurate experiment is more accurate. LOL Joke. The latter simply means the results are to a higher degree of.... accuracy e.g instead of to 5, the result could be 5.1235 However a fair experiment is a test carried out under fair conditions. If testing more than once during the experiment you have to be sure that things remain at the same level i.e. Temperatures Amounts of reactants Time must remain the same..
Something you would either keep the same or change during a practical, to ensure the experiment is a fair test.
It means that except for the independent variable (the only factor that you change) you remain the other variables constant. To keep the control variables the same. Then this is a controlled experiment (fair test). Hope this helps :)
experiment means
The experiment is what you test and how you test it. Your entire project is based on the experiment.
Because if you don't conduct the experiment right you would not get a fair answer to the fair test.

Fair test means, that in a experiment/project everything is perfect and fair.
Repeat the experiment and make sure it is fair.
