㈠引入新课
[
来源:学#科#网]
上一节课我们学习了质量及其测量工具——托盘天平,那么托盘天平如何使用呢?我们这节课就来学习托盘天平是怎样测量物品的质量的。
㈡新课内容
⒈学会使用天平
请对照托盘天平,仔细阅读托盘天平的使用说明书,熟悉托盘天平的调节与使用方法。
⑴托盘天平的使用
①使用天平时,应将天平放在水平工作台上。
②使用前,将游码移至称量标尺左端的“0”刻度线上;调节横梁上的平衡螺母,使指针尖对准分度标尺中央的刻度线。
③称量时,天平的右盘放置砝码,左盘放置需称量的物品;添加砝码和移动游码,使指针对准分度标尺的中央刻度线,此时砝码质量与称量标尺上的示数值之和,即为所称量物品的质量。
④从砝码盒中取砝码时,必须用镊子夹取,不要用手提取。
⑵托盘天平的保养
