地球内部运动引起的地形变化是义务教育小学科学教科版教材五年级上册地球表面及其变化单元的第二课。这节课的容量比较大,既要研究火山,又要研究地震以及火山和地震引起地形的变化。本课所涉及的教学内容离学生的生活实际较远,即使有的学生通过影片或其他的途径感受了火山和地震,但是这种感受还是比较感性的、比较肤浅的。因此在课前参与的作业中布置学生查找火山、地震的资料。地球和宇宙相关的理论探究课比较难教学,她不像生命世 Terrain changes caused by the Earth’s internal movement is the second class of the fifth grade of the Earth science textbook compulsory education primary school and the surface of the unit of change. The capacity of this lesson is relatively large, it is necessary to study volcanoes, but also to study the earthquake and changes in terrain caused by volcanoes and earthquakes. The teaching content involved in this lesson is actually far from the life of students.
