Description

Natural phenomenon teaching demonstration model

Technical Field

The utility model relates to a teaching equipment field especially relates to a natural phenomenon teaching demonstration model.

Background

Natural science is a general term for science of various departments of studying inorganic nature and organic nature including biological properties of human beings. The natural science is a science for studying organic or inorganic things and phenomena in the nature, and includes astronomy, physics, chemistry, geoscience, biology, and the like, and geography.

The object of recognition is the whole world, i.e., various types, states, attributes, and motion forms of substances in the world. The recognition task is to reveal the nature of the phenomena occurring in nature and the processes occurring in nature, and then to grasp the regularity of these phenomena and processes in order to interpret them and to foresee new phenomena and processes, opening up various possible ways to make reasonable and purposeful use of the laws of nature in social practice. The natural sciences believe that the phenomenon of being hyper-natural, random, and paradoxical is nonexistent. The two most important pillars of natural science are observation and logical reasoning. The laws in nature can be guided by the observation and logical reasoning of nature. If the observed phenomenon is different from the prediction of the law, then the hyper-natural factor is absent, either because there is a mistake in the observation, or because the law considered correct so far is wrong. Following traditional usage, science can be understood as bioscience (involving biological procedures) and distinguished from physical science (involving the physical and chemical laws of the universe) and chemical science.
