科学老师备课搭子|用重物驱动小车全套课件

科学老师备课搭子｜用重物驱动小车全套课件

五上教科版科学这节课环节多，装置讲解、分组实验、数据研讨一个接一个，备课要翻的资料不少。

这套《用重物驱动小车》打包齐了：图片版 PPT、逐字稿、教案设计三件全配上。从玉兔号月球车导入，到垫圈挂绳装置拆解、逐个加垫圈做实验，再到数据研讨、控速挑战，每个环节讲什么、怎么过渡都写好了。

实验课就怕乱，逐字稿里连计时口令和挡车提醒都给到了，照着走就行。上课前一晚翻一遍，第二天心里有底。 #教科版科学 #五年级科学 #运动和力 #科学课件 #小学科学教案 #科学实验课 #课堂多媒体课件 #科学老师备课 #小学教学资源 #五年级上册
