Final answer:
Nature science encompasses various disciplines including physics, chemistry, biology, geology, and astronomy, unified by methods of observation, experimentation, and logical analysis to understand natural phenomena.
Step-by-step explanation:
The best definition of nature science refers to the distinctive way of gaining knowledge about the natural world. This encompasses a collection of disciplines such as physics, chemistry, biology, geology, and astronomy, which are all aimed at understanding how nature operates. By employing methods of observation, experimentation, and logical analysis, scientists in these fields work to develop accurate facts, scientific laws, and theories that explain the phenomena observed in the natural world. The ultimate judgement in science is what nature itself discloses through these scientific methods. Furthermore, certain disciplines like biophysics and biochemistry are interdisciplinary, utilizing both life and physical sciences to enrich our understanding of the natural world.
