中班科学活动电动玩具教案设计意图篇三
新《纲要》中指出:科学教育的目标强调幼儿能运用各种感官,动手动脑,探究问题。
幼儿在玩玩具时,经常在观察、思考:汽车为什么会开?车灯为什么会亮?对电池的作用产生浓厚的兴趣。本次活动结合《纲要》精神,体现“生活化、经验化、操作化”的特点,从幼儿的兴趣入手,充分挖掘电池潜在的教育价值。
在活动中,通过给幼儿提供足够的操作、探索的时间、机会,引导幼儿运用观察、比较电池,了解电池的外形特征;调动幼儿的已有经验,动手操作、安装电池,了解电池的安装方法及作用,并体验安装成功的喜悦。
在整个活动中,充分体现“师生互动,生生互动以及与材料的互动原则。教师的开放式提问,发展了幼儿的发散性思维;幼儿间的讨论、交流,发展了幼儿的口语表达能力,经验也得到了积累;支持、引发幼儿与材料的互动关系,通过操作、摆弄电池、探索电池的奥秘。
1、对电池产生兴趣,初步了解常用电池的外形特征和用途。
2、乐意参加安装电池的.探索活动,感受成功的乐趣。
3、愿意与同伴一起操作、交流。
4、培养幼儿对事物的好奇心,乐于大胆探究和实验。
5、激发幼儿对科学活动的兴趣。
常用电池若干个(1、5、7号),电动玩具若干个,电池图片一张
一、导入:幼儿选择各种电动玩具玩,引出活动主题:“电池”
二、通过观察、比较,了解常用电池的外形特征,尝试从多角度发现电池的差异。
1、幼儿观察、比较电池。
2、幼儿操作,教师引导幼儿从不同角度去比较,鼓励幼儿与同伴一起操作、交流。“你们发现这些电池那些地方不一样?”“这些电池有没有一样的地方?”
3、出示电池图片,师生共同小结电池的外形特征。
三、幼儿尝试为各种不同类型的电动玩具安装电池。
1、教师提供不同型号的电动玩具,让幼儿根据自己的生活经验自由选择、自由操作安装电池,让玩具动起来。
2、请幼儿讲述自己的操作过程,并一起讨论操作中遇到的问题。
“你是怎样装电池的,电动玩具才会动起来?”
教师针对幼儿的操作情况,举典型事例。
四、幼儿再次探索为各种不同的电动玩具安装电池
1、鼓励幼儿找到电池盒内的标记进行安装电池,尝试为各种不同类型的电动玩具进行安装。
2、师生共同交流操作中遇到的困难和问题,总结经验。
3、幼儿初步了解电池的用途及培养初步的环保意识。
1、让活动中没有正确安装电池的幼儿继续操作练习。
2、在日常生活中继续寻找使用电池的物品,并尝试自己安装电池。
3、环保教育:不乱扔废旧电池。
为了激发他们的认识兴趣和探究欲望,培养他们乐于尝试、勤于动手的习惯。设计了尝试性、操作性和探索性较强的尝试学习活动——好玩的电动玩具。活动主要通过让幼儿各种各样的玩具和不断地探索,一步步地揭开电池的各种秘密,让孩子们在轻松愉快的环境中认识电池并学会安装电池的方法。

1、让幼儿认识各种电动玩具及其共同的特征。
2、使幼儿知道电池在电动玩具中的作用以及正确使用电池的方法。
3、发展幼儿的好奇心和探索玩具的兴趣。
幼儿人手一个电动玩具。
一、创设情境,引起兴趣。
1、教师扮演师猫头鹰博士,邀请幼儿去电动城玩。
2、幼儿在电动城里选一件自己喜欢的玩具玩一玩,玩过以后,告诉大家,自己玩的是什么?它会怎么样?
3、幼儿分散按意愿玩,教师巡回指导,提示幼儿进行观察。
4、幼儿交流观察结果。
二、寻找电池。
1、教师提问。电动玩具为什么有的能动、有的能响呢?(幼儿互相发表自己的想法)2、幼儿自由探索和操作,寻找电池:请你们在玩具身上找找看,是谁供给它们电,使它们动的?
3、幼儿交流探索结果,是电池让电动玩具动起来的。
4、请一名幼儿上来将电池拿掉,其他幼儿仔细观察。
5、教师简单小结:看来,真是电池起了作用,电池可以供电给玩具让它们能动、能亮,电池的本领可真大啊!
三、学习正确安装电池。
1、幼儿观察电池,了解电池的基本结构。
2、幼儿初步尝试给玩具装上电池,让它们能再动、再跑。(幼儿尝试装电池,教师巡回观察,不作指导)
3、请一名幼儿上来边操作边讲述,教师引导其他幼儿观察。
4、请没有完成的幼儿再次尝试操作,教师巡回指导。
5、教师小结:小朋友真能干,知道了电池是各种各样的,可以用在很多地方,还学会了正确地装电池,可你们要记得电池用完了以后一定要拿出来,不然会把电动玩具给弄坏的,记住了吗?
四、结束活动。
教师扮演猫头鹰博士,欢迎幼儿下次再到电动城来玩。
