应用物理知识不仅可以让我们了解自然灾害产生的机理,知道它们对人类的破坏程度.掌握防止灾难产生的方法,树立环保意识,而且通过对这些现象的研究,利用低层次分化,高层次组合,提炼出适合中学学习的物理模型,加深物理知识的理解,培养科学探究能力,形成科学态度与科学精神. Applied physics knowledge not only allows us to understand the mechanism of natural disasters, to know their degree of damage to humans, to master methods of preventing disasters, to establish environmental awareness, but also to use low-level differentiation and high-level combinations through the study of these phenomena. To refine the physical model suitable for secondary school learning, deepen the understanding of physical knowledge, cultivate scientific inquiry ability, and form scientific attitude and scientific spirit.
