Experimentation is considered to be the investigation of a phenomenon. During this study, all the necessary variables that in some way influence it will be eliminated or introduced. Experimentation is considered one of the stages of the scientific method.

Experimentation is commonly used to verify certain hypotheses that are held about something, generally these investigations are carried out in laboratories. Once the theory is formulated, the researcher must verify if it is real, if it is true, for this, endless experiments must be put into practice, changing the variables that participate in the process and thus be able to verify if it is fulfilled.

One of the creators of the experimentation process was Galileo Galilei, he wanted to verify many of his hypotheses through experimentation, when he began his research on the fall of bodies, he wanted to verify that if we launched at the same time and from a same height two objects one light and one heavy, these would fall with the same speed and would reach the ground at the same time, in order to verify this theory he carried out many experimentation and measurement processes that led him to determine exactly that his theory was true by For example, Galileo climbed to the top of a tower and from there launched several objects of different weights, which reached the ground simultaneously, thus proving that his theory was true.

Physics and Chemistry are also part of the experimental sciences since their object of study and their problems have to be exposed to experimentation.
Biological experimentation is based on the controlled experiment, where there are groups of people chosen at random and who are comparable in all aspects, except for the one that is being studied, always taking into account the variation related to the material. biological. You should always keep in mind certain useful rules such as paying close attention to every detail, always keeping specific notes and being objective when issuing results.

Experimentation, like any other research measure, is not necessarily unquestionable; the ineptitude of proving an assumption experimentally does not show that it is wrong.
