* Chemistry: The composition, structure, properties, and reactions of matter.

* Astronomy: Celestial objects and phenomena.

* Geology: The Earth's structure, processes, and history.

* Botany: The study of plants.

* Zoology: The study of animals.

* Ecology: The study of relationships between living organisms and their environment.

2. Social Sciences: These study human behavior and society, including:

* Anthropology: The study of human societies, cultures, and origins.
