五上科学测量力的大小,21页课件打包齐

五上科学测量力的大小，21页课件打包齐

教科版五上《测量力的大小》三件套：21 页 PPT、配套逐字稿、教案设计。

内容顺着拔河的生活场景展开，弹簧测力计四大件讲到牛顿单位，两个实验——测重力和测拉力——步骤图配视频位，研讨备了橡皮筋对比和生活中的弹力，末尾玉兔号月球车拓展把课推到月球上，板书设计和实践作业也齐了。

逐字稿连实验视频的播放时机都标好了，拿来就能上课。备课时间省下来，留给孩子多拉几次弹簧。 #教科版科学课件 #五年级上册科学 #测量力的大小 #弹簧测力计 #科学课件PPT #教案逐字稿 #小学科学教学 #运动和力单元 #科学备课资料 #小学教师素材
