幼儿园小班说课稿科学篇一
在《3—6岁儿童学习与发展指南》中对科学领域有明确的定义:
幼儿的科学学习是在探究具体事物和解决实际问题中,尝试发现事物间的异同和联系的过程。幼儿在对自然事物的探究和运用数学解决实际生活问题的过程中,不仅获得丰富的感性经验,充分发展形象思维,而且初步尝试归类、排序、判断、推理,逐步发展逻辑思维能力,为其它领域的深入学习奠定基础。
幼儿科学学习的核心是激发探究兴趣,体验探究过程,发展初步的探究能力。成人要善于发现和保护幼儿的好奇心,充分利用自然和实际生活机会,引导幼儿通过观察、比较、操作、实验等方法,学习发现问题、分析问题和解决问题;帮助幼儿不断积累经验,并运用于新的学习活动,形成受益终身的学习态度和能力。
幼儿的思维特点是以具体形象思维为主,应注重引导幼儿通过直接感知、亲身体验和实际操作进行科学学习,不应为追求知识和技能的掌握,对幼儿进行灌输和强化训练。
在《落下来》这个活动中,我既结合着科学活动的核心和幼儿的思维特点,又结合着《纲要》的要求进行。《纲要》中提出:教育要贴近幼儿的生活来来选择幼儿感兴趣的事物和问题,要积极引导幼儿对身边常见事物和现象的特点,变化规律产生兴趣和探究欲望,怎样对幼儿的探究欲望创设一个宽松、开放、和谐的气氛是设计科学活动必须要考虑的问题。物体的下落,对于孩子并不陌生,幼儿都有的生活经验,所以给他们创设了一个和谐的气氛激发幼儿的探究欲望。
在本次活动中,我为幼儿提供了生活中熟悉的材料,创设了3个尝试点,引导孩子通过探索,层层深入的感知物体下落的速度、形态、及落地后的样子的不同,以及与物体本身与外力都有一定的关系。
1、观察、比较物体下落时的现象,对物体的下落现象感兴趣。
2、能用记录的方式和语言来表达观察到的现象。
3、在探索的过程中体验成功的快乐。
让幼儿在自主探索活动中,感知物体落下来这一科学现象。
幼儿能用自己的符号来表示自己的发现。
为顺利完成以上教学目标,在活动准备方面,特作如下安排:
第一次操作所需材料:卡纸、积木、海洋球、手帕、海绵、羽毛,纸杯、蛋糕盘、记录单和笔。
第二次操作所需的材料同上,每人增加一份记录纸和笔。
第三次操作同样大小的手工纸人手一张。
说教法新《纲要》指出:"教师应成为学习活动的支持者、合作者、引导者。"活动中应力求"形成合作探究式"的师生互动。
1、情境教学法:
爱玩是孩子的天性,设置一个有趣的能够引起孩子探究动机的情境是科学教育活动的关键,因此我在活动中以"闯关"为前提,带领幼儿进行一关又一关的挑战游戏,难度渐深,层层递进,让幼儿不断有成功感的同时更加乐意主动地去进行挑战,增加了幼儿探索的兴趣。
2、动手操作法:
它是幼儿科学活动的基本方法。《纲要》指出"提供丰富、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"本次活动安排了三次操作活动。第一次是引起兴趣后第一次操作,让幼儿感知物体下落这一现象,并引导幼儿能够用语言进行描述。第二次操作是在让幼儿掌握"同一高度、同时落下"这一要求,观察物体下落的现象。这个过程中我也尝试着让幼儿通过合作的方式完成。探索后能用自己的符号来进行表格的记录,从中了解物体下落是与物体的轻重等因素有关。第三次操作,让幼儿在自主探索中发现,原来同种物体的下落与形状、大小以及风力有关。
3、观察、记录法:
新《纲要》指出"用多种的方式表现、交流、分享探索的过程和结果"因此在探索、感知物体下落现象的环节中我引导幼儿以观察、记录等形式来表达他们的探究过程和发现,以此从中得出相应的结果。本次记录也重在让孩子积累记录的经验,所以在重点方法的记录上我和孩子们进行了探索。
说教学过程本次活动,以《新纲要》为指导,借鉴建构主义理论及做中学思想,由浅入深,由表及里,让幼儿在互动式、开放式、探究式的教育活动中,自主地、能动地学习。
1、创设游戏氛围,激发幼儿探索的欲望,引导幼儿观察物体的下落现象并清楚表达。
兴趣是幼儿产生学习动机的重要因素,因此,我以"闯关游戏"开始,激起幼儿想玩、想探索的兴趣。结合着幼儿的兴趣进行了第一次操作,让幼儿通过自己的操作感知物体下落这一现象,并能够用语言进行描述。
2、观察、比较两种物体下落现象的不同,用记录方式表达观察到的现象。
第二次操作,在操作中感知"同一高度、同时落下"的两种物体下落现象的不同,用记录的方式表达观察到的现象。
首先进行老师示范,让幼儿初步感知"同一高度"及"同时落下"。《纲要》指出"提供丰富、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",因此,我为幼儿准备了多种多样不同的物体,让幼儿通过操作认识到"同一高度,同时落下",为之后的环节奠定基础。
这一环节通过幼儿亲自动手操作来感觉到自己有新发现,体验到发现的乐趣和求知的快乐。在操作完成后,我们鼓励幼儿用自己的符号来记录,发挥了幼儿的想象及创造力。从幼儿的记录表中,我们总结出一些关于记录"速度"的一些好的记录方法,并且通过记录表也发现原来物体的下落速度与轻重等因素有关。
3、第三次操作,探索同样的纸出现不同的下落速度。
第二次操作,我们是让孩子发现不同物体下落的不同现象,第三次操作则是更进一步,主要是让幼儿去探究让相同物体下落速度有明显区别的方法。
在这一环节中,我先出示两张相同的纸让幼儿去猜测是否会同时落地,制造悬念,再次引起幼儿探究的兴趣,在老师示范后,幼儿发现原来两张相同的纸也并不是同时落到地上的,从中引出,风力与物体下落的关系。在探索改变纸下落速度的过程中,我放手让幼儿自己去寻找方法,让他们去折、去团、去撕……从幼儿自己的操作中,我们总结出原来物体下落和形状也是有关的。
科学活动重在让孩子探索,激发幼儿的探索兴趣。活动中,我充分以幼儿为主体,和幼儿在探索中解决问题。每一次的操作都是一个挑战,挑战的难度逐渐加大,在一次次的挑战中,一次次的成功中,我们让幼儿感受到了成功的喜悦以及自豪感,同时让幼儿对科学探索更加有了兴趣及信心。

“幼儿关注和发现生活中的科技成果。”这个目标属于科学领域的范畴。《纲要》中提出:从生活或媒体中幼儿熟悉的科技成果入手,引导幼儿感受科学技术对生活的影响,培养他们对科学的兴趣和对科学家的崇敬。这里提到了几个关键词:生活、熟悉,可见我们选择的科技成果的内容应该是从孩子的生活出发,为幼儿所熟悉的。
根据这个指导思想,我选择了“手机”,因为现在的家庭中至少有两部手机,有的甚至更多,孩子用手机打过电话、拍过照片、玩过游戏、听过音乐,他们对手机有一定感性认识,教师把课的重点定位在引导幼儿感受科学技术对生活的影响。
但作为小班第一学期进行的教学内容,我选择了幼儿最为熟悉的两大功能:打电话与拍照入手,引导幼儿去关注和发现手机的其它功能,让孩子感受科学技术对生活的影响。
1、通过观察、比较、讨论等手段,让孩子了解手机的部分功能,使幼儿知道手机给人们的生活带来了很大方便。
2、通过打电话游戏,让孩子初步感知点与数的对应,学习打电话的方法。
通过观察、比较、讨论等手段,让孩子了解手机的部分功能,使幼儿知道手机给人们的生活带来了很大方便。
学习打电话的方法。
1、观察比较固定电话与手机的相同点与不同点,知道手机的功能之一:打电话。了解手机的特性:小巧、携带方便,人们随时随地都可以使用它。
2、比较照相机与手机,了解手机的功能之二:拍照片。(出示平时用手机给宝宝们拍的照片进行引导。)
3、了解手机的其他功能:(如打游戏、听音乐)
师:科学家可聪明了,他们发明的手机本领越来越大,除了可以打电话、拍照以外,你还知道手机有什么本领吗?(如听音乐,可现场演示)引导幼儿去关注手机的其他功能,进一步感受科学技术的发展和变化。
师:宝宝现在想不想爸爸妈妈,可是,我们在幼儿园,爸爸妈妈在上班,怎么办呢?(教师在这里要注重情感的引导)
教师有选择性地提供一组号码的小圆点,让孩子数数小圆点的数量,数对了,电话就通了,并让孩子真实地与家长进行对话。
教师在小结时要提醒幼儿不能随便打电话。
引导幼儿继续去关注手机的其他功能(如摄像、闹钟、上网等功能),进一步感受科学技术的发展和变化。
1、能从生活中幼儿熟悉的科技成果中选材。我们对孩子的教学既要来自于生活,又能回归生活,为生活所服务,我所选择的“手机”孩子既熟悉又陌生,熟悉是因为孩子在家中经常接触父母的手机,对它有一定的了解,陌生是因为手机中有许多功能是孩子不熟悉的,因为父母怕孩子弄坏自己的手机而不让他们玩,所以这里就有许多教师可以挖掘的教育价值,引导孩子感受科技成果对人们生活的影响。
2、注重各领域的结合。在第二环节中我设计了打电话,通过打电话游戏,让孩子初步感知点与数的对应,通过真实地打电话学习打电话的方法,在这里,既注重了各领域间的整合,又培养了孩子的口语能力。
3、手机作为一种通讯工具,除了为我们的生活提供方便外,还有其情感因素在里面,我们可以通过手机打电话、发短信,向朋友或家人表示问候,是人们情感交流的工具。在活动设计中我注重了对幼儿情感的引导。

幼儿园小班说课稿科学篇五
《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。我这次活动的选材就来源于生活。石头是构成自然生态环境的一种无生命的物质,同时也是幼儿经常接触的事物,比如在几次户外活动时,我看到有几个孩子特别喜欢去捡石头玩,用石头在地面上、墙面上、花坛边等各地方敲一敲,一边玩一边兴奋地叫同伴一起过来听石头敲击所发出的`声音。我意识到这是一个很好的生成课程,于是就设计了这个小班的科学活动《奇妙的石头碰碰响》,希望通过游戏引起孩子们对探索不同的物体能发出不同的声音的兴趣,引导他们在“玩中学”在“玩中求发展”,就如《纲要》中所说:“要引导幼儿对身边常见事物和现象的特点、变化规律产生兴趣和探究的欲望。”发现和感觉到周围世界的神奇,体验和领悟到科学就在自己身边,保持永久强烈的好奇心和求知欲。
从“新纲要”科学领域目标的表述中可以看出:科学教育的价值取向不再是注意静态知识的传递,而是注重儿童的情感态度和儿童探究解决问题的能力。根据纲要
精神,结合小班幼儿年龄特点,我制定以下目标:1、感知石头的基本特性,乐意参加玩石头的游戏,体验玩石头的乐趣。2、尝试自由探索,发现硬的物体和石头碰撞可以产生响亮的声音,而软的物体与石头碰撞则没有声音,并愿意大胆表述。
本次活动的重难点为“通过探索,发现硬的物体和石头碰撞可以产生响亮的声音,而软的物体与石头碰撞则没有声音。”在活动中我采用了探索比较法来解决难点,通过两次探索比较让幼儿发现这一特性。1、物质准备:幼儿人手两块石头;若干件硬的物品(木头积木,塑料积木,金属勺子);若干件软的物品(海绵,毛绒玩具,毛线团);厚垫子,桌子等。
2、经验准备:已学习节奏乐《闪烁的小星星》。
我通过三个环节“感知特性--探索比较--拓展经验”来达到活动的目标。1、感知特性一开始以“石头展览会”的形式激发幼儿的兴趣,通过观察发现石头不同的颜色、形状、质感,对石头的基本特性有一定的了解,为后面的环节做好铺垫。2、探索比较这个环节是活动的重难点所在。通过两次探索比较,让幼儿发现硬的物体和石头碰撞可以产生响亮的声音,而软的物体与石头碰撞则没有声音,并愿意大胆表述。第一次以集体共鉴的方式,初步感知软硬物体与石头碰撞产生的不同现象;第二次通过自主探索,幼儿运用已有经验的判断进行初步猜测,经过探索验证进一步感知这一现象。3、拓展经验这是活动的延伸环节,进一步增强幼儿对探索石头的兴趣。
幼儿对事物的认识具有形象性、具体性的特点,喜欢直接参与尝试,对操作体验型的活动尤为感兴趣。本次科学活动正符合了孩子们好动手、喜探究的心理特点。活动的目的是培养幼儿动手操作、主动活动的兴趣和创造意识。材料的
提供上既注意材料的平常性,又充分注意了材料的层次性、开放性,幼儿可以尝试用不同的材料、不同的方法,主动探索,体验成功的快乐。

幼儿园小班说课稿科学篇七如今,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。
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。
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。
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。
② 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。

幼儿园小班说课稿科学篇十一
幼儿科学教育活动是指教师的支持和引导下,运用各种感官,通过主动、亲历的动手动脑的活动,对周围事物、现象进行感知、观察、操作,发现问题,寻找答案的探究过程。糖对于小班幼儿来说,是非常喜欢的,而这次的“做中学”实验是在一次偶然的幼儿生活环节中,孩子将糖掉进了水里,老师抓住了此次教育契机,不仅引发了幼儿主动思考,主动探索糖的变化,激发幼儿观察的兴趣,提高幼儿的动手操作能力。
这次活动属于现象观察类活动。对小班幼儿来说,“溶解”现象既无法理解的,又是容易观察的。该活动立足于观察溶解现象的发生过程,而不是讲解糖为什么溶解,符合小班幼儿的年龄特点。在活动中,教师引导幼儿自由讨论溶解现象,允许他们通过自己的想象来寻求解释,对于维护幼儿的好奇心以及养成其思考的习惯是有益的。
小班科学《糖消失了》(第一研)执教:陈梦娇活动目标:
1.通过操作发现糖在水里会慢慢变小慢慢消失,水会变甜。
2.愿意探索发现不同的糖在水里的变化,并愿意与别人交流自己的发现。
3.积极主动参与活动,对探索性活动感兴趣。
1.方糖大量、人手一只杯子。
2.大的透明杯子一只、温开水大量。
提问:1.小朋友,你们吃过糖吗?喜欢吃吗?
2.请你说说糖在嘴巴里会怎样?(变甜、变小等)3.请你猜一猜,把糖放在水里会怎样呢?
1.教师:糖放到水里到底会怎样呢?让我们一起来做个试验吧。
老师把糖放到透明的大杯子里,注入适量的开水,引导幼儿观察。
提问:(1)看一看,糖发生什么变化了?(变小)(2)猜一猜,糖到哪里去了呢?
(3)刚刚还是没有味道的白开水现在会变成什么味道了呢?
2.幼儿猜测回答后请个别幼儿上前品尝糖水,并把自己品尝的结果告诉大家。
教师
小结:糖在水里会变小,慢慢的没有了,水会变甜。
1.幼儿人手一粒糖一杯温开水操作观察提醒幼儿注意不把水泼掉,提醒幼儿有耐心。2.集体品尝糖水。
第一次讨论意见:
1.教师在提问的设计,提问的时机上需不断改进。
2.有幼儿提出糖为什么会化时,应该让幼儿对这个问题作出猜测,激发探索的欲望。
小班科学《糖消失了》(第二研)执教:赵青活动目标:

(3)刚刚还是没有味道的白开水现在会变成什么味道了呢?
2.幼儿猜测回答后请个别幼儿上前品尝糖水,并把自己品尝的结果告诉大家。
小结:糖在水里会变小,慢慢地融化到水里面去了,水会变甜。
1.幼儿人手一粒糖一杯温开水操作观察。2.提醒幼儿注意不把水泼掉,提醒幼儿有耐心。
1.在导入环节,怎样能够更好地激发幼儿参与活动的积极性,符合小班幼儿的年龄特点。
2.幼儿品尝糖果的时候最先注意到的是糖果产生的甜味。教师应当在糖果的变化上适当的提醒幼儿感知糖果大小的变化。
小班科学《糖消失了》(第三研)执教:谢小雨活动目标:
1.通过操作发现糖果在水里会慢慢变小慢慢消失,水会变甜。
2.对溶解的现象产生好奇,并愿意思考“糖怎么不见了”的问题。
3.积极主动参与活动,对探索性活动感兴趣。
每人一小杯水,一块方糖,以及用于搅拌的汤匙。
1.师:你们的桌上有什么?如果把糖放到水里去会怎么样呢?今天请大家自己试一试,仔细看看,糖到水里会怎么样?
2.幼儿试验、观察、表达、交流。
2.幼儿讨论、交流、思考、讲述。
1.教师出示水果硬糖、方糖、奶糖,并出示记录表。
教师:这里还有一些糖也会“化掉”,请你观察一下,它们在“化掉”的过程中有什么不一样?
2.幼儿操作并观察。
3.教师
总结:原来不一样的糖果,在水中溶解的速度也不一样,方糖溶解最快,第二是奶糖,第三是水果硬糖。
1.师:你还知道有什么东西像糖一样,在水里会“化掉”呢?2.幼儿表达交流。
:今天我们发现了一个有趣的现象:糖放到水里去就不见了。请你们回家以后再试一试,还有哪些东西也是这样的。
