大班看不见洞洞的教案篇二

1、知道蛀牙产生的原因

2、懂得怎样爱护自己的牙齿

3、简单了解牙齿的结构,学习正确的使用牙刷刷牙的方法,知道健康的刷牙时间

1、牙刷、牙杯、镜子、封口袋子若干;

2、教学ppt和牙齿模型

3、牙医博士的图片一张

4、《牙医之歌》见附

请牙医博士出场:今天我为小朋友请来了以为很厉害的,我们一起用热烈的掌声请他出来,看看他是谁,好不好?

(出示牙医博士的图片)他是谁呀?想不想知道他是什么医生呢?听一听他怎么说吧!

教师唱《牙医歌》,向幼儿介绍牙医博士

你的牙齿疼过吗?什么时候?为什么疼的?

你认为我们的牙齿里会有洞洞吗?

(照镜子寻找自己的蛀牙)今天呀,牙医博士就是专门小朋友们的牙齿的。牙医博士说了,要想帮助自己的牙齿,就要先找到牙齿哪里生病了。牙医博士给小朋友们准备了好多小镜子,请你们现在就去照照小镜子,找一找自己有没有有洞洞的牙齿,如果有洞洞,那洞洞是什么样子的?什么颜色的?赶快去看看吧!

师幼讨论自己的蛀牙--教师:牙医博士说了,有洞洞的牙齿,叫做蛀牙。还想问问小朋友们,你们知道蛀牙是怎么造成的吗?

师幼讨论蛀牙产生的原因--教师:蛀牙的产生是因为糖或巧克力之类的吃多了,或者小的时候喝了太多的酸奶,再或者含有糖粉的零食、点心吃的太多了,所以才会导致蛀牙的产生。

那我们已经蛀掉的牙齿或者还是健康的牙齿是不是都有应该保护呀?那应该怎样让蛀牙的洞洞消失呢?健康的牙齿又应该怎样来保护好它们呢?

师幼讨论--教师:蛀掉的牙齿,我们可以找牙医博士来补完整。而且我们要注意饭后漱漱口、少吃零食、少吃糖,最重要的是要坚持每天刷牙。只有做到这些了,我们的牙齿才会越来越健康。

(出示牙齿模型)向幼儿介绍牙齿结构(牙龈:保护牙齿的根部,还对牙齿的稳固起着重要的作用;牙齿:咀嚼食物)--幼儿讨论正确使用牙刷、牙膏和刷牙的正确方法,应且个别幼儿上前利用牙齿模型演示--教师,并正确掩饰牙刷和牙膏的正确使用方法和刷牙的正确方法:每天要刷两次牙才是健康的。因为一天吃三顿饭,再吃点水果、点心之类的,虽然每次都漱漱口,但是还是会有残留的东西,如果晚上睡觉之前不刷牙就会导致蛀牙。为什么早上要刷牙呢?因为啊人在晚上睡觉的时候,口腔一直都是闭合的状态,口腔内会滋生很多的细菌,对身体的健康和牙齿的健康都没有好处,所以早上起床也是一定要刷牙的。而且牙医博士还建议我们每次刷牙要刷够2分钟,才能真正的对牙齿有好处呢。

师:老师为你们准备了一首儿歌动画,时间刚好是健康的2分钟刷牙时间。当歌曲和动画结束的时候就是我们刷好牙齿的时候哦!下面我们请马老师为我们拿出牙刷和牙杯,一起来清洁一下我们的小牙齿吧!(幼儿分组拿自己的小杯子用牙刷刷刷牙!)

收拾牙刷(用封口袋子装起来)和小杯子--用小镜子照一照检查一下自己的牙齿有没有刷干净附:

《牙医之歌》

我是一名小牙医,我的本领大!

你的牙齿生病了,就来找我吧!

我来帮它看看病,然后修修它!

保证你的小牙齿,白亮又健康!

大班看不见洞洞的教案篇四

最近我班有几位幼儿的小牙齿掉了,我想到大班幼儿正处于换牙期,为了让孩子保护好自己的牙齿,因此设计了健康活动《看不见的洞洞》。

1、知道蛀牙产生的原因。

2、懂得怎样爱护自己的牙齿。

3、简单了解牙齿的结构,学习正确的使用牙刷刷牙的方法,知道健康的刷牙时间。

1、牙刷、牙杯、镜子、封口袋子若干。

2、牙医博士的图片一张。

3、《牙医之歌》见附。

一、活动导入:

请牙医博士出场:今天我为小朋友请来了很厉害的专家,我们一起用热烈的掌声请他出来,看看他是谁,好不好?

(出示牙医博士的图片)他是谁呀?想不想知道他是什么医生呢?听一听他怎么说吧!

教师唱《牙医歌》,向幼儿介绍牙医博士。

二、通过观察、讨论,使幼儿了解蛀牙产生的原因。

你的牙齿疼过吗?什么时候?为什么疼的?你认为我们的牙齿里会有洞洞吗?

(照镜子寻找自己的蛀牙)今天呀,牙医博士就是专门来帮助小朋友们的牙齿的。牙医博士说了,要想帮助自己的牙齿,就要先找到牙齿哪里生病了。牙医博士给小朋友们准备了好多小镜子,请你们现在就去照照小镜子,找一找自己有没有有洞洞的牙齿,如果有洞洞,那洞洞是什么样子的?什么颜色的?赶快去看看吧!

师幼讨论自己的蛀牙?

教师小结:牙医博士说了,有洞洞的牙齿,叫做蛀牙。还想问问小朋友们,你们知道蛀牙是怎么造成的吗?

师幼讨论蛀牙产生的`原因?

教师小结:蛀牙的产生是因为糖或巧克力之类的吃多了,或者小的时候喝了太多的酸奶,再或者含有糖份的零食、点心吃的太多了,所以才会导致蛀牙的产生。

三、通过讨论,了解保护牙齿的方法。

那我们已经蛀掉的牙齿或者还是健康的牙齿是不是都要应该保护呀?那应该怎样让蛀牙的洞洞消失呢?健康的牙齿又应该怎样来保护好它们呢?

师幼讨论。

教师小结:蛀掉的牙齿,我们可以找牙医博士来补完整。而且我们要注意饭后漱漱口、少吃零食、少吃糖,最重要的是要坚持每天刷牙。只有做到这些了,我们的牙齿才会越来越健康。

四、了解牙齿的基本结构及作用,学习正确使用牙刷和牙膏。

(出示牙齿模型)向幼儿介绍牙齿结构(牙龈:保护牙齿的根部,还对牙齿的稳固起着重要的作用;牙齿:咀嚼食物)幼儿讨论正确使用牙刷、牙膏和刷牙的正确方法,让个别幼儿上前利用牙齿模型演示。

教师小结,并正确演示牙刷和牙膏的正确使用方法和刷牙的正确方法:每天要刷两次牙才是健康的。因为一天吃三顿饭,再吃点水果、点心之类的,虽然每次都漱漱口,但是还是会有残留的东西,如果晚上睡觉之前不刷牙就会导致蛀牙。为什么早上要刷牙呢?因为人在晚上睡觉的时候,口腔一直都是闭合的状态,口腔内会滋生很多的细菌,对身体的健康和牙齿的健康都没有好处,所以早上起床也是一定要刷牙的。而且牙医博士还建议我们每次刷牙要刷够2分钟,才能真正的对牙齿有好处呢。

师:老师为你们准备了一首儿歌动画,时间刚好是健康的2分钟刷牙时间。当歌曲和动画结束的时候就是我们刷好牙齿的时候哦!下面我们请翁老师为我们拿出牙刷和牙杯,一起来清洁一下我们的小牙齿吧!(幼儿分组拿自己的小杯子用牙刷刷牙!)

五、活动结束。

收拾牙刷(用封口袋子装起来)和小杯子,用小镜子照一照,检查一下自己的牙齿有没有刷干净。

附:

牙医之歌我是一名小牙医,我的本领大!

你的牙齿生病了,就来找我吧!

我来帮它看看病,然后修修它!

保证你的小牙齿,白亮又健康!

通过学习,幼儿了解蛀牙形成的原因以及对人身体的危害,幼儿还掌握了正确的刷牙方法,有利于养成早晚刷牙的卫生习惯,收到良好的效果,整个教学活动层层递进,从材料,形成到组织的各个环节,教师的语言以及幼儿的表现等,都是个性化浓郁的,不断激发孩子欲望的,孩子主动探索主动学习发现知识的一次活动。总之,是把枯燥的科学活动和其他领域有机的结合在一起,达到了整合的目的。
