Want this question answered?
In the Science Fair, 'constants' are things that remain the same in your experiment. For example, you might want to keep the temperature constant for the duration of the experiment.
Repeat the procedure at least twice, preferably 3 times. Only keep 1 thing in your experiment the same. Change the materials or anything you are using.
make sure everything is the same
Use same equipment/apparatus
it is a variable that you allow to stay the same throughout the experiment.

The control is what you keep the same through the whole experiment. I'm doing an experiment for a science fair this yer and its: What things can remove permanent marker from fabric. my control would be, the amount of "stuff" i use and the type or marker. hope it helps ♥
things about your experiment that you are going to keep exactly the same
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 :)
A fair test is when you test something equally changing the variables but keeping everything else the same
Use same equipment/apparatus
Fair test means, that in a experiment/project everything is perfect and fair.
things in an experiment that stay the same are called constants.
