动物的自我保护方法多种多样,像保护色、拟态、硬壳、硬刺、装死等等。喜爱小动物是孩子们的天性,动物保护自己的方法是孩子们很喜欢了解的内容,但它不容易通过直接的实验或探究进行学习,老师也不可能有那么多的资料,所以这个活动需要通过收集资料的方式进行,在收集资料、整理资料的基础上通过讨论交流等手段获取科学知识,是科学讨论型的活动。这种活动首先要调动家长、孩子一起收集各种有关动物自我保护的资料,如图书、图片、网上下载的资料。同时运用现代多媒体的手段,如准备好相关的课件和录像资料更生动、形象、直观地展示动物的自我保护方法,更有利于孩子的讨论、交流、学习。
种子对于幼儿来说并不陌生,但是幼儿所见到的大部分都是农作物的种子,都是靠人类来种植的。在自然界中还有许许多多的野生植物,他们有各种各样奇特的种子,能借助于外界或自身的力量遍布世界,这对于生活在城市的幼儿相对就比较陌生了,然而正是因为幼儿在这方面经验的欠缺,所以能使幼儿产生更浓厚的探索兴趣。《种子的旅行》这一活动,通过让幼儿收集种子实物和种子的图片,通过各种途径积累相关的知识经验,在此基础上充分利用课件和录像资料,让幼儿了解种子的神奇、了解种子传播的秘密。根据活动内容的特点和幼儿的知识经验情况,确定目标如下:1、初步了解几种常见种子的传播方式,知道种子的外部形态及其传播方式之间的关系。2、能根据种子的传播方式对种子进行分类。3、知道种子传播的目的是为了繁衍后代。
《新纲要》中指出:科学教育应利用身边的事物与现象作为科学探索的对象。本次活动《彩色的阳光》就是取材于我们身边最熟悉的一种现象:阳光。阳光虽然在我们身边,给我们的生活带来了很多方便,但很多幼儿都不知道阳光原来是多彩的!另外基于阳光的不可见性,我决定通过各种材料,让幼儿在动手探索中去产生疑问,调节认识。大班幼儿对自然界有着强烈的好奇心和探究欲望,他们已有一些动手操作的经验,但他们对物质世界的认识还必须以具体材料为中介和强梁,在很大程度上借助于对物体的直接操作。所以我为幼儿准备了一些常见的材料,我根据陈鹤琴“玩中学、玩中教”的思想,让幼儿通过玩一玩、看一看、说一说、填一填,认识太阳光的七种色彩。从玩一种材料→玩多种材料,从填简单的记录表→填复杂的记录表,我的每一个过程都是从幼儿的年龄特点以及认知特点出发。
《纲要》中指出:在终身教育的背景下的高质量的幼儿教育,强调科学教育首先要精心呵护和培植幼儿对周围事物及现象的好奇心和探究欲望。为了让化学实验活动成为幼儿科学领域的一项实践活动,尝试让化学小实验走进幼儿,将化学小实验变为幼儿感兴趣的游戏探索活动,不仅使幼儿自始自终保持浓厚的探索兴趣,而且让幼儿感受到化学小实验的奇妙,特设计此活动。大班科学课《含淀粉的食物》就适合在本精神指导下进行指导幼儿探索实验。在日常生活中,幼儿对各类食物有着较多的色香味等方面的体验,也不断接受着不偏食、合理营养等科学知识教育。但对食物中到底含有哪些营养成份(比如淀粉),我们怎样去区别不同事物含有不同的营养成份呢?因此本节课设计了以下活动目标:1.观察化学小魔术,激发探索兴趣和积极尝试的欲望。2.了解淀粉遇到碘酒会变成蓝色的现象,初步了解生活中哪些常见的食物含有淀粉。3.在科学游戏中尝试运用多种感官感知科学现象,会用语言表达自己的探索结果。
时下,正是春光明媚、万物复苏的季节,花开草绿,小树苗发芽了,树林里一派郁郁葱葱的景象,令人心旷神怡。生活中有各种各样的树,它们长得都不一样,从外形上看有的粗、有的细、有的直、有的弯、有的高、有的矮。从叶片上观察,也是千姿百态,树的种类也有很多,有常绿树、落叶树等。树是我们人类的好朋友,可以美化、绿化环境,没有树就没有人类美好的家园。所以,设计这一课题既符合幼儿的现实需要——探究树的各种各样和奇妙性,激发幼儿的好奇心,又有利于幼儿的长远发展。培养幼儿的环保意识和热爱大自然的美好情感。本教材的重点、难点是:了解各种各样的树及树木给动物、人类带来的好处,教育幼儿爱护树木。
l、在图形的反复变化中,训练幼儿思维,提高操作能力。2、通过让幼儿反复对三角形、正方形、梯形、圆形等图形进行变化操作,引导幼儿发现图形之间可以相互变化,转换,它们可以变出不同的数量的各种图形。3、培养幼儿利用各种图形组合成各种物体的情趣。本节课我塑造了一个深受孩子们喜欢的人物形象贯穿在整个教学活动之中,开始部分通过模仿机器人幽默、诙谐的声音设置悬念,一下子吸引住了孩子,也为后面活动有效的开展做了一个铺垫。第二个环节,通过让孩子看看、说说等方式让孩子对已有的知识经验进一步巩固和提升。在此基础上,进行了本节课的重点环节-----“寻找图形变换的秘密”。孩子们在自己动手操作的过程中,探索着,最后,寻找到图形之间可以相互变换的这一规律。结束活动时,又给孩子们呈现出一组图形拼贴画,激发孩子们动手制作的强烈愿望,孩子们在此次活动中体验到了学习数学的乐趣。此次活动,我最大的收获就是看到孩子们学习时的那种喜欢探索的精神,我们教师应该为孩子创造出更多的机会,当然,在此次活动中也存在着许多的问题:
2、目标定位:针对我们班幼儿的已有经验和发展水平,挖掘教材的教育价值,我设定了以下几个活动目标:①感知空气的存在,发现空气流动产生风的现象;②运用所获得的体验探索怎样让水上的风车转动起来;③能大胆表述自己探究的过程和结果,体验与同伴分享的快乐。3、活动的重难点:空气虽无所不在,但它看不见、摸不着,因此我将本活动的重点定位在感知与发现空气流动产生风,难点为迁移经验解决让水上风车转动起来的问题。
选取这一题材是因为该内容层次清楚,且所使用的材料是深受幼儿喜爱的,易激起幼儿探索的强烈愿望,使幼儿在活动过程中处于主动地位。我确定本活动的目标为:1.使幼儿了解电池的外形、种类、及简单的功能。2.在尝试性操作活动中,鼓励幼儿探索正确使用电池的方法。3.培养幼儿尝试性精神及探索科学的兴趣。教具准备:收集多于幼儿人数的电动玩具,形状、大小不一的电池,电池装配示意图,会发光的花两朵。该教具弥补了图片枯燥、不生动的缺陷,而其可操作性特点,既使幼儿一目了然,又便于教师讲解,强调重点。
二、目标确定大班幼儿对事物表面特征的观察已积累了一定的经验。在本次活动中,通过寻找探索发现影子的奥秘,激发幼儿探索事物本质特征的兴趣,科学教育活动是引导幼儿亲自探索和发展获得有关经验的过程。《纲要》指出:科学教育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,针对本班幼儿科学教育特点,我确定了以下目标:1、引导幼儿观察发现影子的特征,知道影子的存在。2、探索发现影子的形成原因。即:光线照在物体上,物体挡住光线就产生了影子,并发现光源位置与影子的位置的关系。3、萌发幼儿探索科学的兴趣及求知欲望,发展幼儿的观察、比较、合作、判断的能力。三、重点、难点1、难点:光源位置与影子位置的关系2、重点:光线照射在物体上,物体挡住光线就产生影子。四、教学准备:根据教学目标和《纲要》中指出的,尽量创造条件让幼儿实际参与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,我做了以下准备:1、选择阳光灿烂的日子进行教学活动2、把多功能厅布置成一个光影实验室、投影仪
世界上的植物有很多种,而每一种植物又都有着自己独特的地方。植物们在外形、生长方式等方面都存在着许多的不同。由于环境资源的破坏,有的植物繁殖过多,而有的植物又濒临灭绝……在这样一个广阔的植物世界之中蕴涵着多种多样的教育价值。大班幼儿对植物有了一定的认识和了解,通过各种教学活动,幼儿已经初步认识了园内的各种花草树木,但是,幼儿的有关植物的知识和经验是零散的,需要教师给予孩子们归整和梳理,帮助孩子们形成一个有关植物的比较完整的概念,更重要的是激发幼儿热爱大自然的花花草草,热爱整个世界,热爱整个地球的美好情感。这才是一个完整儿童、完整人的基本素养。通过教学活动,教师可以引导幼儿通过观察、比较、探索、讨论等等,大胆表述对植物世界的认识,发现植物之间的不同,探讨植物的独特之处,了解植物世界和我们人类世界之间互相依存的关系,激发幼儿热爱植物和保护植物的美好情感。在《奇特的花草》这个活动中,我着重解说一下植物的自我保护。因为我认为,植物的自身保护与它们的生存环境和它们各不相同的外形特征有着很大的关联。另外,如今对独生子女进行自我保护意识的教育是十分重要的,而植物的自我保护教学活动的开展恰恰可以激起幼儿进行自我保护的意识。二、说活动目标基于教材的综上特点,我从认知、情感、能力三方面来制定这次活动目标。1、了解植物保护自己的方法,知道植物自我保护的方法与生存环境、外形之间的关系。2、能把观察到的植物的信息大胆地用语言表达出来,学会按一定的标准进行分类。3、激发幼儿探索植物世界奥秘的兴趣,树立自我保护的意识。目标(1)(2)综合了认知和能力两方面的目标。幼儿的科学教育重在激发幼儿对科学活动的兴趣,给予幼儿正确的科学知识,掌握一定的科学方法,所以重点目标定位在认知和能力两方面。其中“知道植物自我保护的方法与生存环境、外形之间的关系,学会按一定的标准进行分类”是本次活动的难点,因为幼儿能够对植物的各种自我保护的方法进行分析分类,这是更高层次的。目标(3)是社会情感目标,通过活动激发幼儿探索植物世界奥秘的兴趣,同时树立自我保护的意识。这三个目标中蕴涵了科学能力的培养、主动探索的经验获得和对事物归纳总结能力的提高,体验了目标的综合性和层次性。
二、说教材 《3-6 岁儿童学习与发展指南》指出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。我们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。三、说活动目标 根据中班幼儿的年龄特点、实际情况以及《3-6 岁儿童学习与发展指南》为依据,我确立了认知、能力、情感方面的目标。认知目标: (1)初步了解当物体挡住光线便会产生物体的影子的现象。.(2)了解探究影子的变化与物体的距离和光位置有关系。能力目标: 积极探索,用记录表记录实验结果并大胆交流自己的想法。情感目标: 体验合作探究影子的快乐,萌发对科学的兴趣。四、说重点难点 我认为幼儿园科学活动的主要性质是让幼儿探索事物的具体现象和获得科学经验为主要目的。因此,我本次活动的重点:感知影子的有趣和影子的形成。难点:引导幼儿参与探索,了解影子的变化与物体的距离和光的位置有关系,并学会用记录表记录验证结果。
一、说教材:刚升中班幼儿可能会对调色活动本身感兴趣,他们的兴趣只是停留在操作上。所以本活动的主要是为幼儿提供观察、探索的机会,让幼儿在主动活动中使用颜色,同时充分感受颜色的丰富性。使幼儿的兴趣转移到对活动中出现的科学现象的兴趣上,从而引发进一步探索的愿望。因此我选择了科学活动:《会变的颜色》这节课。二、说教学目的:1、通过引导幼儿自己动手做实验,发现颜色的奇妙变化,激发幼儿对调色的兴趣。2、在示范的基础上,教幼儿学念儿歌,理解儿歌内容,并引导幼儿进行一定的创编。
二是规划引导。科学规划是创新创业的重要前提,衡阳县委县政府把规划编制工作纳入重要议事日程。加强基地规划。精心规划高新技术企业创新创业孵化基地、互联网企业创新创业孵化基地和电子信息企业创新创业孵化基地,通过规划来拓宽创新创业空间。加紧产业规划。按照“1163”产业布局,重点发展生物医药、先进装备制造、电子信息三大产业。界牌陶瓷循环经济产业园以瓷泥精深加工为入口,带动工业陶瓷、特种陶瓷、礼品陶瓷、日用陶瓷等高端陶瓷产业发展。发展西渡都市型产业、关市铁矿采选、井头石材开采及加工、演陂建材产业、库宗桥拆装家具、高端红木家具等木器加工产业集聚区。通过规划引导广大民众选准创业领域、选对创业合伙人。
一是宣传引导。通过政府网站、电视台、电子显示屏、微信公众号等多个宣传平台,积极开展了创业专题宣传活动20余次,发放政策宣传资料10000份,悬挂横幅标语120余条,并在《今日蒸阳》报刊等新闻媒体开办了创业专栏,大力宣传创新创业优惠政策,深入挖掘和报道衡阳县创新创业典型,营造促进全民创新创业的良好舆论氛围,引导衡阳县广大民众积极投身创新创业。如衡阳县大安乡的胡起辉回乡在演陂镇创办湖南美佳妮卫生用品有限公司,在代工NAMUR品牌出口美国、俄罗斯、新加坡等国的同时,建立专业研发团队,创立森林风、威威虎、青橙之恋等自主品牌畅销本县和周边省市,公司年产值7000万元,创税200多万元,提供就业岗位近300个。为表彰创业典型,衡阳县还举办了“衡阳县十大创业之星”评选活动,对美佳妮等获评企业分别给予1万元奖励,并制作专题宣传片在县电视台播出,起到了很好的宣传带动作用。

The theme of this unit is human and nature, focusing on the theme of wildlife protection. Nature is a complex ecosystem, in which there are delicate balance between animals and plants. Because of the role of the food chain, the extinction of one species will produce influence, causing a series of chain reaction. Large scale extinction of species will have a serious and even irreversible impact on the ecosystem, resulting in immeasurable losses. Therefore, it is of great significance to protect wild species. To protect wild species is to protect human beings themselves. The motto of this unit is "when the buying stops, the killing can too,” which is a public service advertising slogan to protect wildlife. It tells people that every rhinoceros horn, every fur, every bowl of shark fin soup, every Ivory product, and every tiger bone product, etc. consumed by human beings, are innocent wild animals slaughtered behind them. The mission of wild aid is to ban illegal trade in endangered wildlife and mitigate climate change. It aims to educate the public to reduce the consumption demand for endangered wildlife products through public publicity and improve the awareness of environmental protection.1. Improve the awareness of wildlife protection by acquiring the knowledge of wildlife protection.2. Focus on environmental protection and protection of all lives.3. Analysis of the living environment of wild animals with appropriate thinking mode.4. Skillfully use the vocabulary and grammar knowledge of this unit to cultivate self-study ability according to the unit content5. Develop cooperative learning ability through discussion and other ways1. Enable the Ss to talk about the current situation of wild animals.2. Guide the Ss to summarize the main idea of each paragraph as well as the main idea of the text.
