An experiment can go wrong for many reason. The number one reason can simply be due to human error. Other factors could be the design of the experiment, a spill done in the experiment, or a miss calculation.
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.

You measure the ambient temperature before the experiment in case the experiment is sensitive to ambient temperature. You want to record all of the environmental factors that might affect the experiment before starting it. You measure the ambient temperature after the experiment for the same reason, and also in case the experiment affected the ambient temperature. Depending on the experiment, environmental factors may need to be considered when analyzing the results.

The factors that are kept the same in an experiment are the constants.The factors that aren't kept the same in an experiment are the variables.
what is the factor that can change an experiment
changable factors
Factors that are kept the same in an experiment are called constants.
what are the factors that can change in an experiment
Variables.

Constants are the factors which do not change. Variables are the factors which change. If that is what you are referring to.
You don't want a lot of the factors && different things in an experiment to be changed because if they are all changed every now and then, it will completely change the experiment.
