1、大象版五年级下册科学教案任课教师：第一单元：春天的故事第一二课时：春天在哪里教学目标：1.引导学生联系生活经验和参与观察活动，激起对春天的兴趣，为本单元的学习作好准备。2.引导 初步了解表达与交流的常用方式和基本方法。教学过程：一、提出问题1.引入：春天是怎样的？你们能在我们校园里找到春天的影子吗？2.师：关于春天，同学们有什么问题？填写在“问题银行”里。3.师：我们可以选择什么方式来讲述春天的故事呢？（提示：诗歌、绘画、童话剧、调查报告等。）二、表达与交流（一）故事与绘画1.出示图片。这是美丽的春天图，图上有什么？（太阳、云、树、草地）看着这张图可以讲一个非常精彩的故事，先讲图上有的东西，然

2、后再讲图上没有的和自己想象出来的东西。边看图边思考。（提示：想象屋子里、树下或草地上有一些什么动物，正在干什么？）2.请一同学们讲述，可以和老师说的不同，但要有次序地说清楚。评价同学们的讲述，启发同学们大胆地展开想象。（二）童话剧播放歌曲“春雨沙沙”，讨论下春雨的情景。组织同学们演唱并用声音和动作来表现。三、布置作业：初步思考寻找春天的计划。文档编码:CB10J6J9T4O9 HV9K3J4G6O9 ZQ3K1R3X6E6文档编码:CB10J6J9T4O9 HV9K3J4G6O9 ZQ3K1R3X6E6文档编码:CB10J6J9T4O9 HV9K3J4G6O9 ZQ3K1R3X6E6文档编码:
