幼儿园科学说课稿篇一
很多家长在与我们交换意见的过程中,常常提到自己的孩子在家里就餐时,喜欢用勺,不喜欢用筷子,或不会用筷子,而科学证明,长期使用筷子会对幼儿小手肌肉的发育起到良好的促进作用,同时促进大脑相应功能区的完善和发展,家长很希望老师能说服孩子多用筷子,因为孩子们最听老师的话。为此,我在课堂教学活动中设计这个科学实践活动,目的在于通过这个活动,让幼儿了解筷子的用途,在游戏活动中获得乐趣,从而喜欢并正确使用这一工具。
活动目的:
1、了解筷子的产生及用途,知道筷子是中国人独特的发明创造。
2、尝试使用筷子进行各种实践和游戏活动。
3、培养幼儿小手肌肉的灵活性和各手指配合的协调性。
活动准备:
1、每个幼儿一副筷子,一个不锈钢小碟子。事先按6个一组分好后放入大托盘中并用餐巾布遮盖起来。
2、每6名幼儿分为一个小组,每组一个不锈钢水果盘,放入煮熟的五香胡豆粒,花生粒和豌豆粒。
3、录音机一台,活泼欢快的儿童乐曲磁带一盒。
活动重、难点:幼儿正确操作筷子,并用筷子开展各种活动。 活动过程:
1、导入活动。
师:我给大家讲个谜语,大家猜猜是什么。姐妹双双一样长,一起工作一起忙,冷冷热热都经过,酸甜苦辣一起尝,猜一样日常生活用品。 幼:筷子。
师:是的,今天老师就给小朋友们带来了筷子,(出示筷子)它可是我们中国古代人的发明,那时的人们用竹子削成这样的两根细竹棍,一头细,一头粗,开始人们称它为“箸”,后来又叫筷子,别小看这一双细细的筷子,无论面条,米饭,青菜,肉食,甚至小豆粒,吃任何东西都难不倒它,它既可以这样夹菜,也可以当叉子,又方便又卫生,后来中国人就习惯了用筷子吃东西,并且一代一代传下来。现在,它可是我们吃东西的时候离不了的好伙伴。你们说,筷子是不是很神奇呢?你们想不想来试一试?
2、学习活动。
① 请每一组的小组长为幼儿分发筷子与小碟子,幼儿将各自的筷子按老师的要求拿在手上。
② 师:先将筷子象老师这样拿在手上,细的一头向下,粗的一头向上,且两只筷子的两端要对齐,然后用大拇指,食指夹住,将中指放在两根筷子之间,这样,我们的筷子就能够自由的开合,夹取东西了。现在。让我们互相看看,谁的小手最灵巧。(幼儿间相互交流,检查,老师则巡回指导,并帮助那些还不能正确持筷的幼儿掌握要领。) ③ 师:现在,让我们举起我们手中的筷子来做个筷子操吧!
放音乐,幼儿跟随老师练习筷子使用的各种模仿,如:并拢筷子拨饭,张开筷子夹菜,横着筷子挑面条,竖着筷子叉馒头,搅动筷子搅拌等等,反复多次练习。
3、实践活动。
① 请小组长分发果盘。
② 师:小朋友们非常能干,这么快已经学会使用筷子了,现在老师有好吃的东西请大家吃,不过,我有一个要求,吃的时候,大家要用手里的筷子夹着吃,而不是手或别的东西,那样不卫生。大家先将喜欢吃的豆子夹到自已的碟子里,再用筷子夹着吃,吃多少就夹多少,不要浪费,如果还想吃,再去盘子里夹,大家都记住了吗?就让我们开始吧!
③ 放音乐,幼儿边吃边交流,老师一边巡回指导,帮助那些掌握得还不够好的幼儿,一边和孩子们交谈,品尝食品。

幼儿园科学说课稿篇三
尊敬的各位评委老师:
大家上午好! 今天我说课的题目是《美丽的彩虹》,本次活动选自幼儿园多元能力实践课程大班下册科学领域,下面我将从教材分析、活动目标、活动的重点与难点、活动准备、教学与学法、活动过程六个方面来进行说明。
首先我对教材进行分析,先说一下我的设计思路,正如《纲要》中所要求的,选取事物要贴近幼儿生活,就拿"彩虹"这一自然现象来说吧,它常常出现在夏天雷雨后,云层中的水珠大量聚集时,经过阳光的折射,就会在天空中出现美丽的彩虹。但往往孩子们还未仔细欣赏时,它转瞬即逝,犹如昙花一现,让人难以捉摸。根据以上情况便生成了《美丽的彩虹》这次活动。
接下来我对幼儿现状进行分析:大班的孩子探索欲望强,能够相互合作也有竞争意识,而且喜欢动手,敢于尝试。在生活中感觉自己很棒,信息十足。《纲要》中指出,教育活动内容的选择要既适合幼儿的现有水平,又有一定的挑战性;既符合幼儿的现实需要,又有利于其长远发展;既贴近幼儿的生活来选择幼儿感兴趣的事物和问题,又有助于拓展幼儿的经验和视野。因此我设计了此次科学活动《美丽的彩虹》。
教学目标是教学活动的起点和归宿,对教学活动起着指引和导向作用。依据大班幼儿的年龄特点和已有生活经验,我制定了以下活动目标:
1、知识目标:认识彩虹,了解它有七种顺序排列的色光。
2、能力目标:尝试用多种方法制造"彩虹",产生对自然界奇妙现象的兴趣。
3、情感目标:愿意与同伴交流,分享探索的过程。
为了更好的完成本次活动,达成以上活动目标,我制定了教学重点和难点:
教学重点是:认识彩虹,了解它有七种顺序排列的色光。
教学难点是:尝试用多种方法制造"彩虹",产生对自然界奇妙现象的兴趣。
为了使活动呈现出趣味性、综合性,寓教育于生活情境中、游戏中,我做了以下活动准备:
1、空间准备:选择晴天开展活动2、物质准备:课件一份,镜子人手一份,盆中装满水,圆珠笔,色拉油,白纸,三棱镜,放大镜,泡泡等。
创设一个宽松的环境,让每个幼儿都有机会参与探究活动,进行尝试,感受参与的乐趣,并能鼓励幼儿自主探索,大胆尝试,因此,我采用了以下教法:
1、提问法:教师有意识地提出幼儿所关注的、感兴趣的、有益于发现某种关系的问题为幼儿指引了探索的方向,减少了探索的盲目性。
2、观察指导法:针对科学探索活动的随机性,以及幼儿的自主建构过程,采取观察指导法是比较合适的,教师通过敏锐地观察,能针对性的进行指导,还能在观察中发现幼儿感兴趣的事情以及其中所隐含的教育价值,把握时机,积极引导。
《纲要》中指出要尽量创造条件让幼儿实际参加探究活动,使他们感受科学探究的过程和方法,体验发现的乐趣。因此,此次活动中,幼儿的具体学法有:
1、操作法:操作活动,是幼儿获得并理解知识的最好的方法,这是此次活动中,幼儿学习活动的主要方法。
2、尝试探究法。在活动中,幼儿通过不断地尝试失败,最终在探索中获得成功。使孩子们懂得真理存在于客观事实之中,并体验探索的乐趣。
3、体验交流法:在探索活动结束后,教师组织幼儿进行探讨、交流,不仅发展了幼儿的语言表达能力,也体现了师生互动,幼儿与幼儿的互动。
为了达到以上活动目标,突出重点,突破难点,我设计了以下活动的过程:
猜谜语,激发幼儿探究欲望--认识彩虹,了解它有七种顺序排列的色光。--学习动手制造"彩虹"--交流总结--延伸活动。 我是让孩子们在操作探索中亲身体验,认识彩虹,了解它有七种顺序排列的色光,克服重点和难点。具体过程如下:
在第一个环节中,我会以猜谜语的方式引起幼儿的注意,激发幼儿的兴趣,把幼儿的注意力一下子带入活动中。(弯弯一座桥,挂在半天腰,七色排的巧,一会不见了。请你猜猜我是谁?引导幼儿根据经验猜出谜底--彩虹.)第二个环节是认识彩虹,了解它有七种顺序排列的色光。
在这个环节中,我通过以下三个小环节来实施:
1、幼儿自由玩镜子。幼儿在玩中和同伴说说从水中的镜子中找到了什么?
2、引导幼儿在水中把镜子对着太阳照射。
3、说说自己的发现。数一数有几种颜色?它们是怎么排列的?
我开始的直接提问是让孩子们拿着镜子在水中自由玩耍,讨论自己的发现,幼儿讨论的问题肯定不充分,之后我用语言提示他们"在水中把镜子对着太阳照一照",这样有目的的引导,让他们自己去发现"彩虹"这一奇妙的自然现象:镜子中能反射出七彩的颜色。
第三个环节是学习动手制造"彩虹"。
经过前一环节的介绍,幼儿对"彩虹"已经产生了浓厚的兴趣,这时教师可以这样引导"这么漂亮的彩虹一会就没有了,怎么办呢?"我直接把问题抛给幼儿,让他们想办法解决,孩子们肯定会说:"我们可以自己做一条'彩虹'呀?那怎么制造'彩虹'呢?"带着这个问题,让孩子们自己寻找材料,如:泡泡、放大镜、三棱镜、圆珠笔、白纸……幼儿自由地尝试用多种方法制造"彩虹",教师用问题设置的方法边观察幼儿操作,边及时地提出问题进行引导,幼儿在尝试操作过程中交流、合作。本环节是运用了尝试法和操作法,也是活动的难点之处。

幼儿园科学说课稿篇五
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。

幼儿园科学说课稿篇七
1、 方法背景 本次活动采用了观察、实验、探究等方法。
试一试: 这是本活动开始的部分。为了让幼儿对活动产生浓厚的兴趣,教师采用了先观察的方法。请幼儿观察教师手中的两种液体——一杯普通的水,一杯红色的水,请幼儿想一想:“把红色的水倒在透明的水里会有什么现象?”教师在到红水的时候应在杯子后面放一张白纸以便幼儿观察。在幼儿看到水分成两层后,请幼儿用自己面前的两种水试一试看看能不能分成两层。让幼儿在浓厚的兴趣下自己亲手实验,引起幼儿实验和探索的欲望。
说一说: 本环节大大激发了幼儿的语言表达欲望。幼儿可以通过自己的亲手的实验和教师倒的水进行比较,教师应该尽可能的让幼儿把自己想说的事说出来,并提出一些让幼儿既感兴趣又能回答的问题以加强他们的自信心。“小朋友倒的水和老师到的水一样吗?那你们知道是为什么吗?”教师可以在幼儿急切的期盼下说出答案“把许多白糖放到红色的水里,使劲的搅,一直到化不开为止。”让幼儿明白,红色的水能沉到水底是因为里面有许多的糖,水就变重了,重的东西自然就沉到了水底。
做一做: 本环节是采取了幼儿自己动手实验的方法。在幼儿实验时知道什么样的液体可以沉到水底,用什么方法制作这样的液体。让幼儿和第一杯水比较,知道两杯水的不同。
一、本次活动完成的《纲要》和国家《科学》课程的目标有: 1、通过幼儿的观察和实验等方法,培养幼儿的动手操作能力和对事物的探究能力。激发幼儿的好奇心和求知欲。 2、 鼓励幼儿运用恰当的方法表达、交流探索的过程和结果。
(一) 活动目标: 1、 通过不同的水的变化,培养幼儿对科学现象的的兴趣并萌发初步的探索欲望。 2、 在幼儿实验的过程中培养幼儿的动手操作能力。 3、 乐意用自己的语言表达出所看到的现象并愿意和同伴交流。
(二) 活动准备: 两杯红色的水,一杯透明的水,白糖。小勺(此材料幼儿人手一份)
(三) 活动流程:
(四) 活动过程: 1、 看一看,想一想 谈话导题:“小朋友看看,老师手里有什么?请小朋友想一想,如果老师把手里的红色的水倒在透明的水里,会有什么现象呢?” (教师把事先调好的红色的饱和的糖水倒在透明的水里,请幼儿仔细观察有什么现象?为了让幼儿观察方便,在透明杯子的后面衬上一张白纸。幼儿可以看见红色的水沉到了透明的水底,成了两层,非常好看。) 2、试一试: 导语:“小朋友,那么你们想做这样好看的水吗?现在请你们用桌上的水来试一试,看看你们能不能做出这样奇妙的水来。”(教师给幼儿分别提供一杯透明的水和一杯红色的水,请幼儿倒一倒,看看能不能倒出两层的水来。) 3、 说一说: 导语:小朋友,你们好看的水做出来了吗?和老师做的水一样吗? (教师请幼儿大胆说出自己实验的方法和结果) 导语:“小朋友知道为什么你们的水不能象老师的一样好看吗?请小朋友看一看老师的
红水和小朋友的红色的水有什么不一样的。”请幼儿仔细观察:小朋友的水很稀。老师的水很浓,象是蜂蜜一样,粘粘的。告诉幼儿:“因为老师在水里加了好多好多的糖,这么多的糖在水里化了,水就变重了。而重的东西是要沉底的,所以红色的水会在下面,透明的水就变成了两层。” 4. 做一做: 请小朋友用自己桌上的东西(一杯红色的水和白糖,一杯透明的水)制作奇妙的水。教师指导幼儿将白糖用小勺盛到透明的杯子里,要强调白糖一定要放多,一直到糖在水里不能化了为止。将放有白糖的红色的水慢慢倒在透明的水里,请幼儿仔细观察,奇妙的水做出来了吗?
(五) 活动评价: 科学活动《奇妙的水》很适合大班的孩子,大班的孩子好奇心强,也很想自己有机会动手制做出他们自己喜欢的东西。本活动难度不大,但很容易看出结果,使孩子们通过成功的结果加强他们的自信心。通过本活动使幼儿在观察、比较和动手操作能力等方面都得到了一定的发展,也使他们的语言表达能力得到了很大的提高。

幼儿园科学说课稿篇九
说课稿是为进行说课准备的文稿,它不同于教案,教案只说“怎样教”,说课稿则重点说清“为什么要这样教”。教师在吃透教材、简析教材内容、教学目的、教学重点、难点的基础上,遵循整体构思、融为一体、综合论述的原则,分块写清,分步阐述教学内容,以进一步提高教学效果。幼儿园科学的说课稿应该怎么制作?
《纲要》中提出:“教育内容的选择既要适合幼儿的现有水平,又有一定的挑战性;既要符合幼儿的现实需要,又有利于其长远发展;既要贴近幼儿的生活来选择幼儿感兴趣的事物和问题,又有助于拓展幼儿的经验和视野和经验”的精神。在我们的生活中有各种各样的纸,有彩色的腊光纸、有薄薄的毛边纸、有光滑的纸、有粗糙的纸……它们有着自己不同的特性,也有着相同的特点:易燃、易撕、易湿、易皱等。正因为纸的品种多样、用处广泛,所以它一直是幼儿最喜欢的物品之一。平常与幼儿的交流与观察中收集到有关幼儿许多关于纸的疑问与话题,如:“为什么在腊光纸上不好画画呢?”“为什么皱纹纸放在水里会退色?”“为什么宣纸放在颜料水会变颜色?”“你们瞧,纸会飞起来!”……这是幼儿的兴趣点。因此这一课题有一定的教育价值,既符合幼儿当前需要——探究纸的秘密,又有利于长远发展,激发其创造的意识,且其教育资源丰富,有孩子们爱看的图书、有爸爸妈妈爱看的报纸、有色彩鲜艳的包装纸……孩子们喜欢用纸折飞机、做纸球、折扇子、写字、画画等,对纸充满了好奇与探究。
根据《指南》科学领域水平目标中提出:“尝试运用基本的科学方法探究问题,能大胆提出问题,发表不同的意见,”以及本班幼儿探索欲望强,喜欢动手操作,能较好地运用语言与同伴进行沟通和交流,会喜欢用自己的方式表达自己的认识和情感来看,我将《纸》定位为一个系列活动,本次活动《神奇的纸》是系列活动之一,着重让幼儿在玩中体验、感知、发现各种纸的不同特性,寓抽象的知识于轻松、愉快的游戏活动中,这与新的课程标准指出:“孩子的学习要来源于游戏,来源于生活。”的情况相吻合的。
根据以上分析及本班幼儿的已有知识经验、能力、发展水平与潜在能力的差异,制定本次目标:
1、引导幼儿积极参与探索活动,发现纸的不同特性。
2、会用简单的方法记录自己的操作过程及结果,乐意与同伴交流。
3、培养幼儿探究精神与分享经验的愿望。
活动中引导幼儿能用各种不同的方法探究纸的不同特性,既是本次活动的重点也是难点。
1、环境创设: 师生共同布置时装表演的舞台
2、经验准备:
(1)教育的整合应该把一日生活看着是一个教育整体,因此,活动前让幼儿了解纸是我国四大发明之一,并知道各种各样纸的名称、种类。开展了体育活动《扔纸球》《揪尾巴》,美术活动《染纸》《撕纸》等。
(2)幼儿有记录、操作活动的经验。
3、物质准备:
(1)时装表演的vcd
(2)师生共同收集各种纸、浆糊、钉书机、剪刀、水彩颜料及记录用的笔、纸等。
1、课件激趣法:
托尔斯泰指出“成功的教学,需要的不是强制,而是激发学生的学习兴趣。”本活动在这方面进行了大胆的尝试。我以看课件“时装表演”引起幼儿的兴趣。引导幼儿观察: “模特身上的服装是用什么做的?”再让幼儿猜想“身上的服装是怎么做的?”通过形象生动、色彩鲜艳的纸服装,让幼儿了解纸时装的材料及制作方法,从而激发幼儿参与的兴趣,及进行时装表演的欲望。
2、记录比较法
《纲要》中指出:“通过探索操作,每个人都有了自己的感受、体验和发现,在头脑中有许多刺激、动觉的经验和一些含糊的可能性,或者有一些处于半意识状态东西,通过思考和适当的方式表达(如绘画、记录表等)形成想法。”因此我采用了记录比较法,它可让幼儿把在探索中的发现及时地记录下来,并通过比较,发现它们之间的秘密。活动中,我向幼儿抛出这样的问题“请你们用这些纸边做边比较,它们有什么不同?”然后把发现记录在纸上。同时,在幼儿操作过程中,我引导能力强的幼儿能用2种以上的方法进行比较,而且依次记录;帮助能力弱的幼儿用1—2种方法比较纸的特性,在此基础上引导幼儿相互交流自己的记录发现,在相互的分享中,师幼共同归纳出纸共同的特点与不同的特性,从而突破活动的重难点。
3、多感官观察发现法:
《指南》的科学领域中提出“学习运用各种感官观察、探索周围的事物和现象”且大班幼儿已具备了一定的观察能力,在观察中幼儿能主动参与,积极性高,能有效的发挥主体作用;因此我们在整个活动中注意引导幼儿运用多种感官来观察、探索、实践,如:用眼看看“模特身上的服装是用什么做的?”用手摸一摸,感知纸材料存在着光滑、厚薄之间的不同,动手折一折、撕一撕发现各种纸之间的差异等。这样幼儿能全身心地投入到活动中,因自己的成功发现而增强自信心,也激发了幼儿参与下一个活动环节的积极性,从而为突破本次活动的重难点打下铺垫。

幼儿园科学说课稿篇十一
我们都知道,动物是孩子们的好朋友,不管是可爱的小兔子、小鸡、小鸭;善良的小马、小羊;凶猛的老虎、狮子……孩子们都非常喜欢。特别是小班幼儿对动物更是充满了好奇,因为那里有他们认识的和不认识的动物朋友。为了激发幼儿热爱大自然,爱动物的情感,让幼儿进一步的认识和了解这些动物,我班进行了主题活动《动物王国》。在活动中,发生了一件事情:
有一天,孩子们在玩抓尾巴的游戏。这时,刘其昕小朋友抓到一条尾巴说:“老师,看我抓到一条大灰狼的尾巴。”听到刘其昕的话,有几个小朋友也参与到其中,纷纷说:“不对,这是小猴子的尾巴。”“这是小兔子的尾巴。”这是孩子对事物的想象,是其创造性的表现,也充分体现出幼儿对动物的喜爱。见他们对尾巴这么感兴趣,我特意找来了一张他们认识的动物尾巴图片,请他们说说这是谁的尾巴,说什么的都有,其实这是他们都认识的小马的尾巴。可是,一旦尾巴和身体分开后,他们就不认识了。
以前在认识动物时都是通过整体进行认识,他们看到一张完整的动物图片时,能很快说出是什么动物,但是将动物分割开来变成一小部分时,就不认识了。这说明幼儿对动物的观察只是整体观察,并没有观察到部分,对动物的整体形象和细节考虑不全面。那么,如何让幼儿更细致、深入地观察和了解动物的外型特征,理解部分与整体的关系呢?针对这个问题产生了本次活动。
(一)、教育目标
如今,科学教育的价值取向不再注重知识的传递,而是注重儿童的的好奇心、求知欲、探索欲和热爱科学的情感。所以,根据这一要求,我将本次活动目标指定如下:
1、鼓励幼儿参与科学活动,激发幼儿求知欲及对科学活动的探索精神。
2、能从动物的局部判断出是哪种动物,并能合作将动物完整的拼出来。
3、通过活动培养幼儿细致的观察能力和动手能力,初步培养幼儿的合作能力。
(二)、教材内容方面
根据制定的目标,选择相应的内容也是置关重要的。确定了活动《猜猜它是谁》,还要结合我班幼儿的具体情况。我根据主题活动《动物王国》里的内容,结合本次活动,收集相关的游戏材料,巧妙地将一些幼儿认识的动物设计在游戏转盘中,并将这些动物分割成二至四块成为孩子们喜欢的拼图,让幼儿通过这些分割图推断出是哪个动物,及在拼图游戏中让幼儿掌握整体与部分的关系。使幼儿在游戏中能积极参与科学探索活动,增强求知欲,充分发挥幼儿的主动性,提高对科学活动的兴趣。
本次活动重点是:鼓励幼儿参与科学活动,激发幼儿求知欲及对科学活动的探索精神。
难点是:理解部分与整体之间的关系。
(三)教学方法:
我在设计本次活动中,采用了以下方法:运用观察法,有目的、有计划的引导幼儿进行科学探索活动,观察法也是幼儿探索科学的基本方法,能使幼儿运用多种感官直观、生动、具体地认识事物,提高幼儿感官的综合活动能力。利用拼图游戏,将动物的整体图片拆开,分成若干片,再让幼儿拼完整。操作法,提供给幼儿合适的材料,让幼儿在自己的活动实践过程中进行探索。教师运用幼儿喜爱的游戏形式,使幼儿在游戏中进行科学探索活动。
(四)教学过程
1、开始部分
教师带领幼儿走进大森林的场景中。引导幼儿观察大森林的场景:“小朋友,我们现在来到了大森林,大家看看大森林里漂亮吗?里面有什么?”让幼儿通过观察,增强幼儿对本次活动的兴趣。激发幼儿的好奇心。通过提问:大森林是谁的家呢?直接导入课题,给孩子一个已有经验的回忆,引导幼儿说出自己已经认识的动物名字,加深幼儿对动物的印象,激发幼儿对动物的喜爱之情。并使幼儿了解大森林是小动物的家,丰富
他们的感性经验和审美情感。鼓励幼儿大胆、清楚地表达自己的想法。为下面内容奠定基础。
2、游戏部分
①游戏:《玩转盘》
转盘上是一些幼儿认识的动物的头部图片,教师出示大转盘,请幼儿自己将转盘的指针转起来,指针指到哪个动物,并说出动物的名字。该游戏的难度不大,动物的特征明显,易于每一位幼儿的独立操作,提高幼儿的动手能力。能针对动物的头部进行推断动物名字,初步学习推断的方法,了解整体和部分的关系。同时,帮助老师了解幼儿对动物的认识程度。将枯燥的认知活动转变成幼儿喜爱的游戏活动,在游戏中掌握知识。
②游戏:《找动物》
请幼儿将老师藏在大森林里的动物部分图片找到,这些动物并不是完整的,有的是动物的身体、有的是动物的脚、有的是动物的头。在找到后,还要推断出它是谁,然后告诉大家自己找到了什么动物。通过幼儿的寻找活动,培养幼儿细致的观察能力,以及喜爱科学活动的情感。为幼儿的'探究活动创造宽松的环境,让每一位幼儿都有机会参与尝试。通过讲述自己找到的动物,培养幼儿语言表达能力。
③将动物的部分卡片送到小动物的家里。
教师将动物的完整图片展示出来,让幼儿通过自己手中的部分动物卡片找出相应的动物图片,进行对应摆放,了解整体和部分的关系。进一步加深幼儿对动物的认识和了解。
3、结束部分——《拼图游戏》:
请找出相同动物图片的小朋友,合作将动物的部分拼成一个整体的动物。通过操作活动,能观察到动物的分割部分的特征,并能相互配合进行拼图,将动物图片拼完整。注重培养幼儿的观察能力和动手能力,尝试培养幼儿与同伴之间的合作能力。
延伸活动:《玩拼图》
在区域活动中,幼儿人手一份动物拼图,能独立将拼图完成。注重培养幼儿的观察能力和独立操作能力,提高幼儿对动物的了解。

幼儿园科学说课稿篇十三
一、说教材
幼儿的科学探究应从身边的事物开始,引导孩子关注周围生活和环境中常见的事物,发现其中的有趣和奇妙,有益于保持孩子们的好奇心,激发他们的探究热情,使他们从小就善于观察和发现。
糖果是幼儿熟悉、喜爱的食品。它精美的包装、形态各异的外形、鲜艳美丽的色彩、奇特丰富的口味,都对幼儿有着巨大的诱惑力,对年龄幼小的孩子来说更始如此。因此,选择这个幼儿既熟悉又感兴趣的内容,让幼儿运用各种感官,主动探索,获得直接的经验,学习认识事物的方法,产生探索周围事物的兴趣和欲望,具有一定的教育价值。
据此,制定如下活动目标:
1、运用多种感官感知糖果的特征 ,初步了解糖的作用。
2、大胆表述自己的发现,并乐意与同伴交流分享。
重难点:运用多种感官感知糖果的特征。
准备:
1、活动室布置成糖果王国,各种糖果散放于活动区、玩具柜等处,在适合的地方悬挂一些糖果。
2、糖果国王头饰一个。
二、说教法。
幼儿对事物的认识直接受到其原有经验的影响。幼儿对糖果有着丰富的感性经验和浓厚的兴趣,这为幼儿的探究和学习活动提供了良好的前提,也为幼儿在活动中发挥主体性提供了保证。活动组织采用拟人化的手法,符合小班幼儿的认知特点。活动过程以幼儿为主体,让幼儿运用各种感官,主动地、较系统地感知糖果的特征。在整个活动中,幼儿始终积极主动,感知能力、操作能力和思维能力均得到了锻炼。
三、说教学程序。
杜威说过,儿童有调查和探究的本能,探索是儿童的本能冲动,好奇、好问、好探究是儿童与生俱来的特点。根据这个特点,我将活动设计成三个环节。
(一)在糖果王国里找朋友。
1、进入糖果王国。
教师戴着糖果国王的头饰,用拟人化的身份引出主题。导入语:小朋友,你们好!我是糖果王国的国王,糖果王国里有许多糖宝宝,你们想不想和他们做朋友呀?
2、找糖果朋友。
进入糖果王国后,请幼儿随意寻找多种糖果做朋友。导入语:孩子们,糖果王国到了,你们看,好多糖宝宝在欢迎你们,快去找个糖宝宝做朋友吧。幼儿根据自己的需要和兴趣选择糖果,是幼儿主动学习的重要前提和基本条件。
(二)感知糖果的特征。
幼儿是勇于实践的探索者,在一日生活中经常表现出积极主动探究和认识周围世界的强烈愿望。该环节通过让幼儿自由地对糖果进行探索,给予充分的自由,体现幼儿的主体地位。
1、幼儿自由的感知,探索糖果的特征,并与同伴交流。
导入语:你们都找到了糖宝宝朋友,请你们看一看,再和旁边的小伙伴说一说自己的糖宝宝朋友是怎么样的?
① 提出探索的要求,帮助幼儿有目的地认识事物。
② 通过探索过程中同伴间的交流讨论,帮助幼儿发展合作能力,增加相互交流与协作的机会,同时相互学习同伴的长处和价值,获得有益的经验。
③ 在幼儿自由探索的过程中,教师的作用是鼓励幼儿轮流表达自己的探究过程和发现,引导幼儿有更多的思考和概括。
2、在教师的引导下进一步感知糖果的特征,并交流自己的发现。
① 看糖果,了解糖果的包装——教师再次以拟人的手段引导幼儿观察糖果的包装。导入语:你的糖宝宝穿了件什么样的衣服?
② 摸糖果、捏糖果,感知糖果的质地——导入语:请你用手摸一摸、捏一捏,然后告诉老师或其他小朋友糖宝宝是怎么样的?
③ 剥糖果,了解糖果的外形、颜色——导入语:现在请你把糖宝宝的衣服脱掉,看看糖宝宝是什么颜色、什么形状的?
④ 闻糖果,感知糖果的气味——导入语:老师闻到了好多糖宝宝的味道,请
你们仔细地闻一闻你的糖宝宝是什么味的?
⑤ 尝糖果,了解糖果的味道——导入语:请你尝一尝,你的糖宝宝味道怎么样?
根据糖果的特征,在教师的引导下,幼儿由内而外、由浅深入地对糖果作了全面细致的观察与认识,通过看、摸、剥、闻、尝等多种感官循序渐进地感知糖果的特征。
3、小结。
通过和幼儿一起回忆,总结糖果的特征,进一步认识和了解糖果,增强对糖果的兴趣。
(三)简单了解糖的作用。
1、提出问题:糖有什么用?多吃糖好不好?
针对问题,引导幼儿大胆讨论、思考糖的作用,及糖对身体的利与弊,初步了解糖的作用。
2、小结糖的作用,渗透吃过糖后保护牙齿的方法。
四、活动延伸
1、组织幼儿进行画糖果、捏糖果的活动。
2、开展“糖果超市”的角色游戏。
幼儿园科学说课稿篇十四
气球是孩子们生活中常见的事物,也是幼儿较喜欢的玩具之一。玩是孩子的天性,尤其是中班段幼儿,基于他们的年龄特点:
活泼、好玩,同时他们对新奇、有趣的事物有了一定的好奇心,常常看到他们三五成群地围着一样东西在观察。作为教师,我们除了在教育教学活动和日常生活中,要限度的满足幼儿的求知欲,还应结合幼儿的生活经验,生成新的教学内容,从而激发幼儿对事物与现象的探索欲。
新纲要指出,教育的过程不是一个简单的传授的过程,而是要幼儿通过自身主动地观察、发现、感知、探索,从而在实践的过程中转化为自身的知识经验。本活动旨在让幼儿通过自己的探索,感知空气的存在,知道为什么气球被突然放飞会到处乱窜等等。
1、知道气球变鼓是因为充入了空气。
2、从气流吹在脸上的感觉,感知空气的存在。
3、感知空气从气球中突然冲出的有趣现象。
1、没充气的气球若干,充足气的气球一只。
2、打气筒若干。
一、气球喜欢吃什么
——分别出示未充足气的气球和充足气的气球。
这是什么?有什么不一样?
——再出示未充足气的气球,引出故事《气球吃什么》
1、气球喜欢吃饼干、馒头、糖果吗?
2、气球究竟吃什么才能鼓起来,变得胖胖的?(气球喜欢吃空气)
——感受气球轻轻吹在脸上和快速吹在脸上的不同感觉
二、我帮气球吃空气
——空气有个怪脾气,很喜欢从气球的肚子里溜出来,怎么样让气球吃得饱饱的,又不让空气溜掉呢?(幼儿个别回答)
——教师示范,重点是如何抓住气球的嘴。
——幼儿操作,教师引导幼儿可以两两合作。
——玩气球:摸摸气球胖乎乎的肚子、和气球碰一碰(身体的各个部位),说说有什么感觉。
三、放飞气球
——猜猜:气球突然放飞会怎样?
——请个别幼儿模仿气球乱窜的样子
——为什么气球放飞后会到处乱窜?是谁给了气球力量?
四、游戏:流星球大战
——组织幼儿来到空地
——游戏:听到教师喊“放射”的口令,全部幼儿放飞气球,表现流星球大战的情形。
请幼儿用绘画的形式表现流星球大战的情形。

1、设计意图:水是我们日常生活中不可缺少的,我们每天都离不开它,每个人离不开它,正因为水与我们生活的密切性,小朋友很早就接触并认识了它,可以说,幼儿天生就爱玩水,在玩水的过程中,发现了很多有趣的而又新奇的现象。《新纲要》中指出,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。因此,我选择了物体在水中的“沉浮”现象,作为科学活动内容,在活动中我为幼儿提供了丰富的可操作性材料,为每个幼儿都能运用多种感官、多种方式进行探索提供活动的条件,通过引导幼儿积极参加小组讨论、探索等方式,培养了幼儿合作学习的意识和能力,学会了用多种方式表现、交流、分享探索的过程和结果。
2、目标定位:
在新《纲要》中指出,五大领域的内容相互渗透,从不同的角度促进幼儿情感、态度、能力、知识、技能等方面的发展,因此,根据幼儿的年龄特点和实际情况,我制定了以下三个方面的目标:
(1)乐于参与科学实验活动,能积极动手动脑主动探索。
(2)感知物体的沉浮现象,并学习记录实验结果。
(3)初步了解改变沉浮的方式。
3、教学重、难点:
(1)教学重点:了解物体的沉浮现象。
(2)教学难点:学习记录实验结果和探索改变沉浮现象。
4、活动准备:
根据《纲要》中指出的“提供丰富的可操作的材料,为每个幼儿都能运用多种感官、多种方式进行探索提供活动的条件。”我做了如下准备:
(1)每组一份实验材料:盛满水的脸盆,小石头、橡皮泥、小木块、泡沫板、塑料瓶、玻璃珠,擦手毛巾。(摆好后用盖布盖上避免分散孩子注意力)(2)记录材料:每组一份彩色记录卡、铅笔。
(3)教师示范材料:鱼缸、小石头、橡皮泥、小木块、泡沫板、塑料瓶、玻璃珠,教学课件
在新《纲要》中指出,教师应成为幼儿学习活动的支持者、合作者、引导者,关注幼儿在活动中的表现和反应,敏感地察觉他们的需要,及时以适当的方式应答,形成合作探究式的师生互动。因此,我采用了以下教法:
1、演示法:
(1)大鱼缸有助于幼儿清楚的观察到教师演示的物体沉浮现象,ppt上也有相应的图片展示。
(2)对于此活动中使用的记录卡,幼儿并未见过,因此,教师的演示是有必要的,通过教师的讲解演示,可以让幼儿直接了解记录卡的记录方法,减少了幼儿盲目探索的可能性。
2、观察指导法:针对科学探索活动的随机性,以及幼儿的自主建构过程,采取观察指导法是比较合适的,教师通过敏锐地观察,能针对地进行指导,还能在观察中发现幼儿感兴趣的事情以及其中所隐含的教育价值,把握时机,积极引导。
《纲要》中指出,要尽量创造条件让幼儿实际参加探究活动,使他们感受科学探究的过程和方法,体验发现的乐趣。因此,此次活动中,幼儿的具体学法有:
1、操作法:这是此次活动中,幼儿学习活动的主要方法。在新《纲要》中指出,教师要为幼儿的探究活动创造宽松的环境,让每个幼儿都有机会参与尝试。因此,我为幼儿准备了各种丰富的、可操作的材料,让幼儿在操作的过程中,发现物体沉浮的现象。
2、记录法:让幼儿将探索结果记录下来,为后面的讨论活动提供依据。
3、体验交流法:在探索活动结束后,教师组织幼儿进行探讨、交流,发展了幼儿的语言表达能力,也体现了师生互动,幼儿与幼儿的互动。
1、导入活动(展示ppt的实验物品图片,让幼儿说出有哪些东西。出示鱼缸,事先用盖布盖住,猜一猜:这些东西哪些会沉,哪些会浮?)刚开始,教师为幼儿设置了一个悬念,通过猜测活动一下子将幼儿的好奇心调动起来,为后面的探究活动奠定了基础。
2、演示活动:先示范两种物体的沉浮,木块和石头。
3、认识活动(你知道这是什么标志吗?)在这里,教师通过讲解、示范让幼儿认识记录卡的使用方法以及表示“上浮”、“下沉”的箭头号标志,为接下来的记录活动做好准备。
4、操作活动(请你来试一试,看结果和自己想的是否一样?)这个环节的分组操作活动是此次活动的重点,教师为幼儿提供了丰富的、可操作的材料,并引导幼儿进行分组探究,既提高了幼儿的自主探究、动手动脑的能力,还培养了幼儿的合作精神。在此环节中,先要讲解操作规则,教师更多的是采用了间接指导和个别引导的办法。
5、记录活动(哪些东西会下沉,哪些东西会上浮,请你用沉与浮的标记记录下来,并出示记录表。)每组让一个幼儿记录。通过记录,使幼儿对各种物体在水中是沉还是浮一目了然,还为后面的总结交流活动提供了依据。
6、交流总结活动(展示每组的记录表)7、探索活动:(让幼儿带着问题继续探索,使幼儿的兴趣持续下去。想一想怎么改变沉浮,例如如何让橡皮泥浮上来或让水瓶沉下去)在此环节中幼儿主动动脑想象,大家一起探索改变沉浮的方法,老师按小朋友的方法进行实验示范。
