definition of natural sciences

The word Science refers to the grouping of knowledge on a certain topic that is achieved by reasoning and experimentation applied in a methodical and systematic way, supported by the scientific method. In accordance with the object of the study, it receives various types of classification.

In the case of natural Sciences, It is the branch of science that is responsible for the study of nature in order to decipher the theories and laws by which the natural world works.

In order to better organize this knowledge, the natural sciences are divided into four major branches, which are Biology, Chemistry, Physics and Geology, each of which in turn has divisions that cover more specific aspects.


It is the science that studies living beings, it is formed in turn by other sciences that allow expanding this study, as is the case of the Biochemistry which is responsible for the study of the molecular mechanisms of life and metabolism, the Histology that passes to the microscopic study of tissues and cells, the Physiology that teaches us how living beings work and the Genetics It deals with aspects related to the laws that govern the inheritance of information between different generations. A great classification of biology is given based on the kingdom to which living beings belong, as is the case of the Zoology that studies the beings of the animal kingdom, the Botany to the vegetable kingdom, the Microbiology studies microscopic beings, Ecology that studies the interrelation with living beings and their environment.


It is a basic science that is interrelated with many other sciences and its object of study is matter, chemistry teaches us what matter is, what its structure and composition are, its types, how it behaves and what its properties are. For this, chemistry has two main branches such as Organic chemistry which is responsible for the study of the compounds that are formed by carbon and the Inorganic chemistry study the molecules that do not contain it. Chemistry relies on the other disciplines to be able to specify this study, deriving sciences such as Biochemistry, Physical chemistry, Petrochemistry and the Astrochemistry, among other.


Once chemistry explains what matter is and how it is formed, physics teaches us how it interacts with its environment, especially the relationship between matter, space, time and energy, in order to understand the phenomena that occur in nature and being able to describe and predict them by identifying the laws that govern them, for this is closely related to mathematics, which is the language of physics. Physics comprises several branches that include Mechanics or science of forces and motion, Thermodynamics which deals with the study of the exchange between heat and energy as well as its balance between systems, Electromagnetism explains phenomena such as electricity and magnetism and the interrelationship with each other, Astrophysics study the laws that govern the universe, Relativity which describes the relationships between gravity and space-time as well as physical phenomena that occur at speeds close to the speed of light, Quantum physics which explains the interrelationship between the particles at the atomic level.


It is the science that is responsible for the study of the earth from its origin to the present, for this it is based on the study of aspects related to the composition and the different processes that occur in rocks, the earth's crust, the atmosphere and the interior of the earth. Geology relies on other sciences such as Physics, Chemistry and Biology, thus deriving its main branches, among which it is found Geophysics, Geochemistry, Geobotany, Zoogeology and the Paleontology.
