1  Branches of Natural Science  Natural Science ✘ a branch of science that deals with the study of the physical world ✘ is knowledge based on the laws of nature and the physical world ✘ is a branch of science concerned with the description, understanding and prediction of natural phenomena, based on empirical evidence from observation and experimentation. Mechanisms such as peer review and repeatability of findings are used to try to ensure the validity of scientific advances. 3  Natural Science ✘ includes all fields of natural science related to the planet Earth ✘ the study of the Earth's structure, properties, processes, and four and a half billion years of biotic evolution ✘ deals with the physical, chemical, and biological complex constitutions and synergistic linkages of Earth's four spheres, namely biosphere(life), hydrosphere(water), atmosphere(gas), and geosphere(rocks and minerals) 5  Natural Science “Science of the Earth” ✘ the primary Earth science ✘ deals with the composition of Earth materials, Earth structures, and Earth processes ✘ it is also concerned with the organisms of the planet and how the planet has changed over time 7  Natural Science “Science of the Atmosphere” ✘ the study of the atmosphere and how processes in the atmosphere determine Earth’s weather and climate ✘ a very practical science because everyone is concerned about the weather; how climate changes over time in response to the actions of people is a topic of urgent worldwide concern 8  Natural Science “Science of the Oceans” ✘ the study of Earth’s oceans – their composition, movement, organisms and processes; oceans cover most of our planet and are important resources for food and other commodities ✘ Oceanographers work to develop the ocean as a resource and protect it from human impact; “utilize the oceans while minimizing the effects of our actions” 9  Natural Science “Science of the Universe” ✘ the study of everything in the universe beyond Earth's atmosphere ✘ a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution 10  Natural Science ✘ the study of living organisms and life processes; the scientific study of life ✘ the sciences concerned with the study of living organisms, including botany, zoology, microbiology, physiology, biochemistry ✘ any science that deals with living organisms, their life processes, and their interrelationships 12  Natural Science ✘ also called plant science, plant biology or phytology, is the science of plant life ✘ the study of plants, including their structure, properties, and biochemical processes ✘ also included are plant classification and the study of plant diseases and of interactions with the environment 13  Natural Science ✘ also known as animal science; is the branch of biology devoted to the study of animal life ✘ the branch of biology that studies the animal kingdom, including the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct, from tiny insects to large mammals, and how they interact with their ecosystems 14  Natural Science ✘ the science of genes and how traits are passed on from one generation to the next ✘ branch of biology that deals with the heredity and variation of organisms ✘ important in learning more about promoting health and preventing disease 15  Natural Science ✘ the identification and description of the structures of living things ✘ branch of biology concerned with the study of the structure of organisms and their parts; deals with the structural organization of living things ✘ the branch of science concerned with the bodily structure of humans, animals, and other living organisms, especially as revealed by dissection and the separation of parts. 16  Natural Science ✘ the study of the inorganic world ✘ A branch of natural science that studies non-living systems ✘ the sciences concerned with the study of inanimate natural objects 18  Natural Science ✘ the branch of science that deals with the structure of matter and how the fundamental constituents of the universe interact ✘ one of the most fundamental scientific disciplines, and its main goal is to understand how the universe behave ✘ studies matter, its motion and behavior through space and time 19  Natural Science ✘ the science that deals with the properties, composition, and structure of substances, the transformations they undergo, and the energy that is released or absorbed during these processes ✘ science that covers the elements that make up matter to the compounds composed of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances 20
