在《在流体中运动》一节的学习中,证明流体在流速大的地方压强小,流速小的地方压强大的演示实验的器材选取方便,容易操作。在上课时,为了调动学生的学习积极性和动手实验能力,我除了让学生自己准备书上的演示实验材料,并分组让学生进行实验展示外,还让部分学习能力比较强的同学积极利用身边的物品做实验,例如利用饮料瓶、塑料吸管、废笔管等日常用品制作了简易喷雾器、逆流而上的小球等实验装置,拉近了课堂与生活的距离,让学生深切地感受到科学的真实性,补充了实验课程 During the study in “Moving in a Fluid”, it was proved that the pressure of the fluid in a place where the flow velocity is high is small and the place where the flow velocity is small is strong. The equipment for demonstrating experiments with high pressure is convenient and easy to operate. In class, in order to arouse students’ learning enthusiasm and hands-on ability, in addition to let students prepare their own demonstration materials on the book, and group to allow students to experiment show, but also to some of the students with relatively strong learning ability to actively use around Experiments such as the use of beverage bottles, plastic pipettes, waste pencils and other daily necessities make simple sprayer, counter-current ball and other experimental devices, which narrow the distance between class and life so that students can deeply feel the scientific Authenticity, supplemented with experimental courses
