幼儿园科学说课稿 幼儿园科学说课稿一等奖【第一篇】

新《纲要》明确指出“科学教育应密切联系幼儿的实际生活进行,利用身边的事物与现象作为科学探索的对象。” 空气是与我们的生命息息相关的,世间万物的勃勃生机都是因为有空气的存在。为孩子提供丰富的材料,让孩子通过眼、脑、手等多种感官去发现问题。使幼儿变被动者为主动学习者、探索者,从而萌发爱科学的情感。

二、说活动目标

活动目标是教育活动的起点和归宿,对活动起着导向的作用。在本次活动中,我根据幼儿的年龄特点和实际情况,设计了两个目标,1、感知空气的存在,掌握空气的特征及作用。2、幼儿对探索自然现象产生兴趣。

三、说活动准备

《纲要》指出,幼儿教师应为幼儿提供丰富的材料,为每个幼儿都能够运用多种感官进行探索活动,为了使活动顺利展开,达到预先设计的教学目标,在此次活动中,我做了如下准备:气球、透明玻璃杯、粉笔、透明盛水容器、蜡烛、打火机、碎纸屑、纸片。

四、说活动重难点

利用有趣的科学操作活动,使幼儿对科学探究活动产生兴趣。好奇心和探究欲望是科学启蒙的关键,它将使幼儿永远保持探究学习的热情。因此,我把培养幼儿的探究兴趣作为重点。

引导幼儿通过老师的示范操作实验,从中找到空气,幼儿受其原有知识经验和思维水平的影响,对事物及其关系的认识和理解,具有很大的表面性和片面性,因此我将这方面作为此次活动的难点。

五、说教法、学法

《纲要》指出,教师应成为学习活动的支持者,引导者,合作者。活动中,教师要心中有目标,眼里有幼儿,时时有教育,以互动的、开放的理念,让幼儿

真正成为学习活动的主体。因此,在本活动中我主要采用了启发提问法、观察发现法、引导发现法、实验操作法等几种教法,使幼儿感受空气的存在。我采用了幼儿在与老师互动中通过猜谜,观察、自主探索、实验操作等学法使幼儿获得认知能力。

六、说活动过程

在活动的开展过程中,我一直本着以幼儿为主题的原则,以激发幼儿的探索兴趣入手,围绕目标,将多种教学形式相结合,使幼儿始终处于积极的自主探索状态,我的活动流程为:猜谜导入——启发提问——实验操作

1、 活动导入部分:

我以猜谜的形式导入活动,激发幼儿的兴趣,使得此次活动能够更好的开展。 谜语:看不见、摸不着,不香不臭没味道,动物植物都需要,一时一刻离不了。(空气)

2、 活动开展部分:

在这个部分,我首先采用了启发提问的方法,问小朋友们什么地方有空气。然后出示气球,让幼儿猜想是谁住在气球里。然后幼儿自己通过实验操作、观察,自主探索的方法寻找身体里的空气,如对这手吹气,捏住鼻子闭上嘴巴,说说这些做了这些动作的感受,幼儿还可以把粉笔头放在盛水的容器中,观察有什么现象发生,并将自己看到的现象说出来。

其次,我采用了实验操作的教学法,为小朋友们变了一个魔术,倒不出来的水。在这个实验中,我还用到了比较的方法,让幼儿能够更加明白其中的道理。我先在一个透明的空杯子里装水,水未满,然后盖上纸片,将水杯倒立起来,让幼儿观察,然后在杯子中装满水,盖上纸片,将玻璃杯倒立,让幼儿观察水有没有倒出来。通过提问:是谁在帮忙。为什么杯子里没有空气,水才不会倒出来?究竟是谁在帮忙?谁那么有力量?引导幼儿交流:杯子里没有空气,外面的空气就会不让水从杯子里流出来。

最后,我将蜡烛点燃后用玻璃杯罩住,让幼儿观察会有什么现象发生。幼儿

之间交流讨论,然后在自己动手操作,把碎纸屑放在桌子上,幼儿分组:用手在周围煽动,观察纸屑的变化。让幼儿知道空气是无处不在的,感受我们的周围充满了空气,只是我们看不见它。

3、 结束部分:幼儿交流讨论实验的结果,说说空气的特征及其作用。

七、说活动延伸

针对本次活动的延伸,我让幼儿探索风和水有些什么奥秘,让幼儿对探索自然现象产生更大的兴趣。

找空气

中班科学活动教案

设计意图:

《纲要》明确指出“科学教育应密切联系幼儿的实际生活进行,利用身边的事物与现象作为科学探索的对象。” 空气是与我们的生命息息相关的,世间万物的勃勃生机都是因为有空气的的存在,,为孩子提供丰富的材料,让孩子通过眼、脑、手等多种感官去发现问题。使幼儿变被动者为主动学习者、探索者,从而萌发爱科学的情感。

活动目标:

1、感知空气的存在,掌握空气的特征及作用。

2、幼儿对你探索自然现象产生兴趣。

活动准备:

气球、透明玻璃杯、粉笔、透明盛水容器、蜡烛、打火机、碎纸屑、纸片。 活动重难点:

重点:利用有趣的科学操作活动,使幼儿对科学探究活动产生兴趣。 难点:引导幼儿通过老师的示范操作实验,从中找到空气。

活动过程:

(一)教师导入活动,引起幼儿兴趣。

猜谜语,引出课题:小朋友们,今天老师带来一位好朋友,我们一起来猜猜它是谁?

谜语:

看不见、摸不着,不香不臭没味道,动物植物都需要,一时一刻离不了。(空气)

(二)提出问题,幼儿猜想。

1、寻找空气:

小朋友们,我们现在一起来找一找,什么地方有空气?出示气球,让幼儿说出谁住在气球里?(空气)

2、幼儿讨论后回答,教师点评。

(三)实验操作,探索活动。

1、身体里的空气

请幼儿伸出一只手,嘴对着手用力吹气,感知身体里空气的存在。或用手捏住鼻子闭上嘴巴,并说出自己的感受

2、粉笔里的空气。

以小组的形式,幼儿分别把粉笔头放入盛水容器中,观察有什么现象发生。并将自己看到的现象说出来。

(四)做实验,感知空气的存在及其特性

小朋友,今天老师要和你们玩个变魔术的游戏《倒不出来的水》

1、出示玻璃杯和纸片。给玻璃杯倒满水,盖上卡纸,然后把杯子倒过来。你能使杯子里的水不倒出来吗?成功的和失败的一名代表来演示。通过对比,幼儿知道只有使杯内无气泡(杯内无空气),才能将杯子倒过来。幼儿再次进行试验,直到获得成功。

2.是谁在帮忙。为什么杯子里没有空气,水才不会倒出来?究竟是谁在帮

忙?谁那么有力量?引导幼儿交流:杯子里没有空气,外面的空气就会不让水从杯子里流出来。

3、将蜡烛点燃请一幼儿用玻璃杯罩住,观察有什么现象发生?幼儿作答,把碎纸屑放在桌子上,幼儿分组:用手在周围煽动,观察纸屑的变化。让幼儿知道空气无处不在,感受我们的周围充满了空气,只是我们看不见它。 活动延伸:

让幼儿自己探索风和水等自然现象有什么奥秘,引发幼儿对自然现象的兴趣。

幼儿园科学说课稿 幼儿园科学说课稿一等奖【第四篇】

说设计意图:

新《纲要》明确指出“科学教育应密切联系幼儿的实际生活进行,利用身边的事物与现象作为科学探索的对象。” 空气是与我们的生命息息相关的,世间万物的勃勃生机都是因为有空气的的存在,,为孩子提供丰富的材料,让孩子通过眼、脑、手等多种感官去发现问题。使幼儿变被动者为主动学习者、探索者,从而萌发爱科学的情感。

说活动目标:

1、感知空气的存在,掌握空气的特征及作用。 2、激发幼儿探索自然现象的兴趣。

说活动重点:

利用有趣的科学操作活动,使幼儿对科学探究活动产生兴趣。好奇心和探究欲望是科学启蒙的关键,它将使幼儿永远保持探究学习的热情。因此,我把培养幼儿的探究兴趣做为重点,精心的呵护和培植。 说活动难点:

引导幼儿通过老师的示范操作实验,从中找到空气,我班幼儿年受其原有知识经验和思维水平的影响,对事物及其关系的认识和理解,具有很大的表面性和片面性。

说教具和学具:皮球、透明玻璃杯、粉笔、透明盛水容器、蜡烛、打火机、碎纸屑、卡纸

说教法、学法

1、教法:本次活动将运用启发提问法、观察发现法、引导发现法、实验操作法等,使幼儿感受空气的存在

2、学法:幼儿在与老师互动中通过猜谜,实验操作、观察获得认知能力的。

说活动过程:一)教师导入活动,引起幼儿兴趣。

猜谜语,引出课题:小朋友们,今天老师带来一位好朋友,我们一起来猜猜它是谁?

谜语:

看不见、摸不着,不香不臭没味道,动物植物都需要,一时一刻离不了。(空气)

出示皮球,让幼儿说出皮球为什么会鼓起来?谁住在皮球里?(空气)

(二)提出问题,幼儿猜想。

1、寻找空气:

小朋友们,我们现在一起来找一找,什么地方有空气?出示皮球,让幼儿说出谁住在皮球里?(空气)

2、幼儿讨论后回答,教师点评。

(三)实验操作,探索活动。

1、身体里的空气

请幼儿伸出一只手,嘴对着手用力吹气,感知身体里空气的存在。或用手捏住鼻子闭上嘴巴,并说出自己的感受

2、粉笔里的空气。

以小组的形式,幼儿分别把粉笔头放入盛水容器中,观察有什么现象发生。并将自己看到的现象说出来。

(四)做实验,感知空气的存在及其特性

小朋友,今天老师要和你们玩个变魔术的游戏(师示范)。 (五)倒不出来的水。 1、出示玻璃杯和厚卡纸。给玻璃杯倒满水,盖上卡纸,然后把杯子倒过来。你能使杯子里的水不倒出来吗?成功的和失败的一名代表来演示。通过对比,幼儿知道只有使杯内无气泡(杯内无空气),才

能将杯子倒过来。幼儿再次进行试验,直到获得成功。 2.是谁在帮忙。为什么杯子里没有空气,水才不会倒出来?究竟是谁在帮忙?谁那么有力量?引导幼儿交流:杯子里没有空气,外面的空气就会不让水从杯子里流出来。

3、将蜡烛点燃请一幼儿用玻璃杯罩住,观察有什么现象发生?幼儿作答,把碎纸屑放在桌子上,幼儿分组:用手在周围煽动,观察纸屑的变化。让幼儿感受我们的周围充满了空气,只是我们看不见它。 反思:本活动让幼儿对实验中发生的现象产生兴趣,在实验中让幼儿反复玩,使幼儿在操作;探索的基础上获得经验,玻璃杯中没有空气,外面的空气就会把水压入杯中卡纸就被吸住,水不会倒出来。同时我在这课添加了用杯子去盖点燃的蜡烛,一下蜡烛就灭了。空气可以支持燃烧。这样吸引幼儿的注意,目的是通过丰富多彩的活动,为幼儿建立一个探索、尝试与交流的平台。,幼儿容易理解。在活动中我运用了启发提问法,观察发现法,引导发现法,实验操作法。幼儿通过猜谜语——寻找空气——试验操作的教学环节,让抽象的自然想象变得具体化了,课堂气氛很活跃,突出了活动的重难点,通过科学探索活动,丰富幼儿的生活经验,利用简单的科学实验使幼儿感知空气的存在,也是这次活动的亮点,让幼儿理解我们的生活离不开空气。 空气无处不在,只要有空隙的地方就有空气。也培养了幼儿的认知能力。
