A scientific control is an element of an experiment or observation designed to minimize the influence of variables other than the independent variable under investigation, thereby reducing the risk of

Take identical growing plants (Argyroxiphium sandwicense) and give fertilizer to half of them. If there are differences between the fertilized treatment and the unfertilized treatment, these differences may be due to the fertilizer as long as there weren't other confounding factors that affected the result. For example, if the fertilizer was spread by a tractor but no tractor was used on the unfertilized treatment, then the effect of the tractor needs to be controlled.

Muybridge's photographs of The Horse in Motion, 1878, were used to answer the question of whether all four feet of a galloping horse are ever off the ground at the same time. This demonstrates a use of photography as an experimental tool in science.

A famous example of discovery being stumbled upon was Alexander Fleming's discovery of penicillin. One of his bacteria cultures got contaminated with mould in which surroundings the bacteria had died off; thereby the method of discovery was simply knowing what to look out for.
