在科技迅猛发展、多媒体应用日益广泛、实验室设备不断更新的今天,在中学物理教学界,低成本教具和自制教具同样受到人们的青睐。课堂上,生活中,如果能用学生熟悉的东西以及随手选取身边的简单器材和“废物”做一些物理实验,不仅成本低廉,完成了教学任务,而且易激发学生的学习兴趣,消除了实验离普通中学和普通学生远的看法,并能让学生受到启发,在课余时间利用身边的材料积极主动地做实验, With the rapid development of science and technology, the increasingly wide range of multimedia applications and the continuous updating of laboratory equipment, low-cost teaching aids and self-made teaching aids are also favored by the people in middle school physics teaching circles. In class, in life, if we can do some physical experiments with the familiar things of our students and simply select the simple equipment around them and “Waste ”, we not only have the low cost, complete the teaching tasks, but also stimulate students’ interest in learning and eliminate Experiments from ordinary secondary schools and ordinary students far from the point of view, and allow students to be inspired in the spare time using the material around their active proactive experiments,
