大班科学公开课神奇的中草药教案反思 大班科学神奇的中草药课件篇三
·初步认识常用的中草药，知道它们可以治病强身健体。
·感受中国传统中医文化的神奇。
·知识经验准备：幼儿已经认识了一些常见的植物
·材料准备：中草药图片
·重点：在植物中对中草药进行分类
·情境表演“医院”
——教师饰“病人”因咳嗽去看病，“病人”不能吃西药所以幼儿饰“医生”开了一贴中草药“川贝止咳露”，“病人”吃后好多了。
——小朋友，你们知道医生给我开的是什么？
·感知了解
——多亏医生给我开了中草药治好了我的病。今天还来了许多中草药朋友，大家用自己的好办法也去认识认识它们吗？
·讨论讲述
——谁能告诉大家你认识哪些中草药朋友？（幼儿讲述，教师出示图片或实物）。
——你是怎么知道的？它有什么神奇的作用呢？（幼儿讨论，讲述）
——还有一些中草药我还不认识，它们又是谁？（教师出示幼儿没有讲到的，如金银花、天麻等）。
——原来，灵芝、人参、川贝、金银花等等这些神奇的中草药有的可以治病，有的可以滋补身体，用处真不小！
·释疑延伸
——这么有趣的中草药，大家还有什么想知道的吗？（幼儿提问，讨论解决）
——那我也要考考大家，你们知道什么人最早发现中草药？中草药还有什么神奇的地方？下面让我们来听听医生的介绍吧！
科学研究应从幼儿身边事物开始，引导他们关注周围生活和常见事物，发现其中的趣味和奥妙，这有利于激发幼儿的好奇心。本次活动从幼儿熟悉的几种常见中草药入手，激发幼儿的探究欲望，并通过参观实物、观看课件等多种形式，层层递进，让幼儿了解中草药的有关知识，从而达到活动目的。
大班科学公开课神奇的中草药教案反思 大班科学神奇的中草药课件篇四
1、对中草药产生兴趣。
2、认识几种常见的中草药，知道它们可以治病。
3、知道中草药最早是人发现并使用的，增强幼儿的民族自豪感。
1、经验准备：家长与幼儿一起收集些常见的中草药实物，并知道其名称与作用。
2、课件(1)：中草药的由来与采制。课件(2)：可以用作中草药的各种动植物及矿物质等。课件(3)：李时珍及《本草纲目》。
3、准备一些常见的中草药
师：前几天，老师让你们和爸爸妈妈一起收集些中草药，这几天小朋友带来了这么多的中草药，你在哪儿找到这些中草药的呢?你还在什么地方见过中草药?引导幼儿联系已有的生活经验想一想，说一说，从而激发幼儿探究中草药的愿望。
1、引导幼儿认识一些常见的中草药名称及作用
师：老师把大家收集到的中草药布置成了一个小小的药店。现在，老师想请小朋友们来仔细看一看、摸一摸、闻一闻这些药材，看看你认识多少种呢?它们叫什么名字?都有什么作用?是植物类的还是动物类的呢?一会儿老师请你来介绍一下。(幼儿自由观看)
(1)提问个别幼儿，介绍自己认识的药材的名称及其功效。
(2)教师介绍名贵药材——灵芝
师:老师也认识一种药材，它是生长在山林中的一种植物，是一种非常名贵的药材，你们知道是什么吗?它叫灵芝，可以治很多病，还可以增强抵抗力，延长寿命呢。据说千年灵芝还可以让快要死去的人活过来呢，神奇吧!
：原来，植物做成的药材是对我们的身体健康的，有些还可以治病呢!
2、了解中药的由来与采制
师：小小的植物也能治病，是哪个国家的人这么聪明发现的呢?我们一下面的课件你就会找到答案的。播放课件(1)。
师：现在大家知道了吗?对!就是我们的祖先发现的，是我们人最早发现植物可以治病的，所以我们称这些药物为中药。你觉得我们祖先聪明吗?他们的确非常聪明，不仅发现了有些植物可以治病，而且还发现了许多动物和矿物质也可以做成药材用来治病呢!那么，哪些地方可以找到这些做成药材的动植物和矿物质呢?
播放课件(2)
师：原来，大自然中到处都可以找到用来制成中药的动植物和矿物质呢，又方便又便宜，而且对我们的身体健康还有很大的帮助，所以，我们离不开大自然，我们要保护好大自然。
3、介绍中药名医李时珍及其著作《本草纲目》播放课件(3)
师：在明朝，有个非常有名的大夫，叫李时珍，为了给老百姓寻找治病的'药材，不怕苦，不怕累，带着徒弟走遍了千山万水，亲自尝尽各种奇花异草，最后终于编写了著名的医药用书《本草纲目》，这本书里面记载了一万多种中草药的作用，是我国医药宝库中的珍贵产物。因为中药的副作用特别小，所以很多外国人十分佩服我们的中医药，也来学习我们用中药来给病人治病。李时珍爷爷真是一个了不起的人呀!
师：这节课我们一起学习了很多关于中草药的知识，谁能告诉大家这节课你学到了哪些关于中草药的知识?个别幼儿发言，教师(如：灵芝是名贵药材，中草药是人发现的，李时珍是一位名医等等)。
组织幼儿参观附近的中药店，增加对中草药的亲身体验。没有条件参观中药店的幼儿园，教师可以创设一个区域，请幼儿进行中药店的游戏。
科学研究应从幼儿身边事物开始，引导他们关注周围生活和常见事物，发现其中的趣味和奥妙，这有利于激发幼儿的好奇心。本次活动从幼儿熟悉的几种常见中草药入手，激发幼儿的探究欲望，并通过参观实物、观看课件等多种形式，层层递进，让幼儿了解中草药的有关知识，从而达到活动目的。
