Knowra Natural science Natural science Natural science is the systematic study of the natural world through observation, experimentation, and evidence-based explanations. It develops and tests accounts of nature using empirical evidence.
Scientific method : A systematic approach to investigating questions through observation, hypothesis formation, testing, and revision. Its investigative practices organize how natural scientists turn questions into testable studies.
Biology : The scientific study of living organisms and their interactions. Biology investigates living systems as one major domain of the natural world.
Natural philosophy : The historical inquiry into nature that preceded the modern separation of scientific disciplines. Natural science developed from older attempts to explain nature through observation and reasoning.
Scientific modeling : The use of simplified representations to describe, explain, or predict features of a system. Models translate evidence and theory into representations that can be examined or used for prediction.
Scientific uncertainty : Limits in the precision, completeness, or confidence of scientific knowledge and measurements. Natural-world systems and finite measurements constrain the certainty of explanations and predictions.
Empirical evidence : Information gained through observation or measurement rather than solely through reasoning or authority. Natural-science claims depend on evidence drawn from observable or measurable phenomena.
Physics : The study of matter, energy, motion, and their interactions. Physics explains fundamental properties and processes across natural systems.
Scientific Revolution : A period of major changes in European science from the sixteenth to seventeenth centuries. New mathematical and experimental approaches helped shape modern natural science.
Environmental science : The interdisciplinary study of the environment and the effects of human activity on it. It combines natural sciences to investigate environmental processes and problems.
Reproducibility : The ability to obtain consistent results when a study is repeated using the same methods and data. Reproducible findings strengthen confidence that evidence is not a one-off result.
