so you can try to see exactly which factors are affecting the dependent variable (the thing you're measuring) "it gives you something to compare your results to" is the basic Y9-GCSE answer =]
Constants are factors in an experiment that stay the same. This should not be confused with controls -- which is a standard used for comparison

* independent variable:in an experiment there is only one variable and its set by the person carrying out the experiment . * dependent variable: measured in all set ups during the investigation. * controlled variables: are quantities that the scientist wants to keep constant. so , the part of the experiment that does not depend on the variable is the controlled variable.

A set of controlled observations that test a proposed explanation are known as an experiment. The proposed explanation is known as the hypothesis of the experiment.

It is the plain set up without the variable tested to compare with the other set ups

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.
I believe the term you are looking for would be a "controlled" experiment. This is the term used when an experiment is done, where one or set of circumstances (which it's outcome is not interfered with or influenced in any way) is cross-referenced with another group or set of circumstances that are "controlled", watched carefully and/or kept the same by the one doing the experiment.
