探秘恐龙：科学二下《恐龙的故事》精品课件

🍞本课以 “恐龙公园实习研究员” 的情境主线，带领学生开启一场博物馆式的恐龙探秘之旅，在趣味任务中认识恐龙特征、学会科学分类，感受古生物世界的奇妙。

🧈开篇以中生代恐龙时代的动画场景导入，用恐龙从繁盛到灭绝的故事快速抓住学生注意力，引出本课主题。

🥞学生以 “实习研究员” 的身份领取任务，开启恐龙家族大调查，逐一认识剑龙、三角龙、近鸟龙、霸王龙、甲龙、腕龙 6 种典型恐龙，了解它们的外形特征、食性与生活习性，感受恐龙世界的多样性。

🧇新知探究环节
“恐龙分类大挑战” 为核心任务，引导学生像科学家一样，根据食性、行走方式、外形特点等标准对恐龙进行分类。

通过小组讨论、记录单填写、生活分类案例拓展，帮助学生理解分类方法的应用，体会科学探究的基本思路，培养科学思维与合作能力。

🍳课堂检测环节
以 “入职培训小检测” 的形式，用特征连线、分类选择、正误判断等题目，帮助学生巩固所学知识，强化对恐龙特征与分类方法的理解。

推荐恐龙相关书籍，鼓励学生课后继续探索，延伸学习兴趣。

🥚 “博物馆探秘” 的沉浸式情境贯穿，画面生动童趣，互动性强，既贴合低年级学生的认知特点，又注重科学探究能力的培养，让学生在趣味任务中掌握恐龙知识，感受科学探究的乐趣，激发对古生物世界的好奇心与探索欲。
