Branches of Science

Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
It's fundamentally about observing and experimenting to understand the natural world.
Several key branches exist, including physical sciences (physics, chemistry), Earth sciences (geology, meteorology), and life sciences (biology, zoology).

Physical Sciences

Physics studies matter, energy, and their interactions.
Key concepts include motion, forces, energy, light, and the fundamental laws of nature.
Areas of study within physics include mechanics, thermodynamics, electromagnetism, and modern physics.
Chemistry studies the composition, structure, properties, and reactions of matter.
It focuses on atoms, molecules, and their interactions.
Key areas include organic chemistry, inorganic chemistry, physical chemistry, and analytical chemistry.

Earth Sciences

Earth sciences study the Earth's structure, processes, and history.
Geology examines the solid Earth, including rocks, minerals, and the processes that shape its surface.
Oceanography studies the Earth's oceans, including their physical and chemical properties, life forms, and processes.
Meteorology studies the atmosphere, including weather patterns, climate, and climate change impacts.
Astronomy studies celestial objects, including stars, planets, galaxies, and the universe as a whole.

Life Sciences

Life sciences study living organisms and their interactions with each other and their environment.
Biology is the fundamental science of life, covering a vast area of study exploring all aspects of life systems.
Zoology studies animals, examining from their morphology, physiology, behaviour, and ecology.
Botany studies plants and their various aspects.
Ecology studies the interactions between organisms and their environment.

Scientific Method

The scientific method is the systematic approach scientists use to investigate questions and solve problems.
It typically involves observing a phenomenon, formulating a hypothesis, designing experiments to test the hypothesis, analyzing data, and drawing conclusions.
Crucial elements of this method include experimentation, observation, measurement, analysis, and drawing conclusions to support or refute hypotheses.
Scientists need to replicate and publish their work for rigorous review and further investigation to verify or disprove statements by others.

Scientific Theories

Scientific theories are well-substantiated explanations of some aspect of the natural world that can incorporate facts, laws, inferences, and tested hypotheses.
Theories are not guesses or opinions. They are robust and well-supported by evidence.
Well-established theories provide frameworks for understanding the universe from atoms to galaxies.
Scientists continually revise and refine theories as new evidence emerges.

Scientific Laws

Scientific laws describe observed patterns in nature.
Laws are concise descriptions of phenomena that appear to hold true under specific conditions, such as Newton's law of universal gravitation.

Importance of Evidence

Science relies on empirical evidence.
Evidence based on observation or experimentation drives all the scientific method processes and is crucial when deciding if observations are valid and theories supported.
Reproducibility, replicability, and peer review are fundamental to ensuring the validity of scientific findings.

Ethical Considerations

Ethical considerations are central to the conduct of scientific research.
Scientists are responsible for ensuring their work is not exploitative, misrepresents findings, or harmful to subjects or communities affected.
Ethical approval of research is essential.
