 "How can we be confident something is true?  Similarly, can we be confident that something we observe is caused by the behaviour of something else?  Whether you are an 11 year old pupil or the greatest scientist the world has ever known, these questions are crucial for scientific investigations."
N. Lyons, Secondary School Science Teacher.

It is only by carrying out a 'fair test' that you can be sure that what you have changed (Independent variable) is affecting what you measure (Dependent variable); rather than some other mysterious variable causing the effect.
