Wikipedia se inhoud: Natuurlike en Natuurwetenskappe
Natuurwetenskap word tradisioneel as die studie van die fisiese nie-lewende aspekte van die wêreld en die hemelruim om ons heen gedefinieer. As 'n groep kan die natuurwetenskappe onderskei word van teologie en die sosiale wetenskappe aan die een kant en van die kunste en die geesteswetenskappe aan die ander kant.
Wiskunde is op sigself nie 'n natuurwetenskap nie maar verskaf baie van die kernmetodes van die ander wetenskappe. Natuurwetenskap poog oor die algemeen om die werkinge van die wêreld deur middel van natuurlike prosesse eerder as deur goddelike ingryping te verklaar. Die term natuurwetenskap word ook gebruik om wetenskap as 'n vak te identifiseer wat die wetenskaplike metode gebruik.
Natuurwetenskappe as term word egter deesdae ook gebruik om te verwys na die begrip wat nader aan die alledaagse betekenis van die term is naamlik die kennis van die natuur en kan dus 'n vak soos biologie insluit.

Immunology – The study of the immune system in all organisms.
Paleontology – The study of prehistoric life, including organisms' evolution and interactions with each other and their environments (their paleoecology).
Dinosaurs – diverse group of animals that were the dominant terrestrial vertebrates for over 160 million years, from the late Triassic period (about 230 million years ago) until the end of the Cretaceous (about 65 million years ago), when the Cretaceous–Paleogene extinction event led to the extinction of most dinosaur species at the close of the Mesozoic era.
Ecology – The study of interactions between organisms and their environment.
Zoology – The study of the animal kingdom, including the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct.
Physical science – encompasses the branches of science that study non-living systems, in contrast to the life sciences. However, the term "physical" creates an unintended, somewhat arbitrary distinction, since many branches of physical science also study biological phenomena.
Astronomy – The study of celestial objects (such as stars, planets, comets, nebulae, star clusters and galaxies) and phenomena that originate outside the Earth's atmosphere (such as the cosmic background radiation).
Chemistry – The study of matter, especially its properties, structure, composition, behavior, reactions, interactions and the changes it undergoes.
Organic chemistry – The study of the structure, properties, composition, reactions, and preparation (by synthesis or by other means) of carbon-based compounds, hydrocarbons, and their derivatives.
Water – chemical substance with the chemical formula H2O. Its molecule contains one oxygen and two hydrogen atoms connected by covalent bonds. Water is a liquid at ambient conditions, but it often co-exists on Earth with its solid state, ice, and gaseous state (water vapor or steam).
Geography – study of the Earth and its lands, features, inhabitants, and phenomena. A literal translation would be "to describe or write about the Earth".
Geology – The study of the Earth, with the general exclusion of present-day life, flow within the ocean, and the atmosphere. The field of geology encompasses the composition, structure, physical properties, and history of Earth's components, and the processes by which they are shaped. Geologists typically study rock, sediment, soil, rivers, and natural resources.
Physics – The study of matter and its motion through spacetime, along with related concepts such as energy and force. More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves.
Energy – an indirectly observed quantity. It is often understood as the ability a physical system has to do work on other physical systems. Since work is defined as a force acting through a distance (a length of space), energy is always equivalent to the ability to exert pulls or pushes against the basic forces of nature, along a path of a certain length.
