【探究缘由】 2004年12月26日的印度洋海域地震并引发的海啸,让全世界为之震惊。面对这样的自然灾害,人类的力量实在是渺小。而人地关系的和谐发展则是我们追求的目标,先让我们进行一次地震模拟实验吧! 【活动目的】地震是一种常见的、突发的自然灾害。在学习有关专题后,我们用实验模拟地震,以正确理解震级和烈度的关系,强化学生防灾减灾自我救护的意识。【知识整合】结合物理学中有关机械波的知识。【活动准备】
【Investigation】 The tsunami caused by the earthquake on the Indian Ocean in December 26, 2004 shocked the world. In the face of such natural disasters, human power is really small. The harmonious development of man-land relationship is our goal. Let us conduct a seismic simulation experiment! [Activity purpose] Earthquakes are a common and sudden natural disaster. After learning related topics, we simulated earthquakes with experiments to correctly understand the relationship between magnitude and intensity and strengthen students’ consciousness of self-help in disaster prevention and reduction. [Knowledge integration] Combines knowledge of mechanical waves in physics. 【Activity preparation】
