Natural Science is a broad field of science that encompasses the study of the natural world and its phenomena. It seeks to understand the physical, chemical, and biological processes that govern the universe and all living organisms within it. Natural Science is divided into various disciplines, each focusing on specific aspects of nature and employing scientific methods to gather data, make observations, and formulate theories. Some of the key disciplines within natural science include:

Physics: The study of matter, energy, motion, and the fundamental forces of nature. It includes topics such as mechanics, thermodynamics, electromagnetism, and quantum mechanics.

Chemistry: The study of matter, its composition, properties, and changes. Chemistry explores the interactions and reactions between different substances.

Biology: The study of living organisms and their biological processes. It includes fields such as genetics, ecology, physiology, and evolutionary biology.

Earth Science (Geosciences): The study of the Earth, its structure, composition, and processes. It includes geology, meteorology, oceanography, and environmental science.

Astronomy: The study of celestial objects and phenomena beyond the Earth. It includes the study of planets, stars, galaxies, and the universe.
