大班科学教案《蚂蚁过冬》教案反思精选

作为一位无私奉献的人民教师,总归要编写教案,借助教案可以有效提升自己的教学能力。那么教案应该怎么制定才合适呢?以下是小编收集整理的教案范文,仅供参考,希望能够帮助到大家

大班科学教案《蚂蚁过冬》教案反思篇一

1、学习用轮廓线表现蚂蚁的结构,并通过头和身体的方位变化表现蚂蚁的各种动态。

2、创造性地想象蚂蚁过冬的有趣情景,培养幼儿对自然现象探究的兴趣。

3、积极参与探索活动,萌发求知欲,体验成功快乐。

4、对蚂蚁有浓厚的兴趣,热爱生活乐于探索。

1、幼儿每人一张"蚂蚁的家"、红黑蓝三色粗细笔。

2、欣赏作品三张:蚂蚁搬花生、蚂蚁宴会、蚁后生宝宝。

3、展示板背景:蚂蚁过冬。

一、导人情景

冬天到了,北风呼呼地吹,动物们开始准备过冬了。每种动物都有自己过冬的好办法。今天我们来做地下考察队,一起走到地下去访问小蚂蚁。

二、欣赏讨论

1、出示背景"蚂蚁过冬"。

小蚂蚁的家在地下的洞里,一个蚂蚁洞有许多洞穴,四通八达,进出非常方便。现在,我们一起走进小蚂蚁的家里去看一看,好吗?

2、打开一号家。

这是一群工蚁的家,工蚁们在干什么呢?(工蚁们在搬一颗花生)小蚂蚁搬的花生怎么这么大?(因为我们人很大,看上去这颗花生很小,可是小蚂蚁很小,看上去这颗花生很大)这么大一颗花生,工蚁们是怎么搬的呢?(有的用头顶,有的躺在地上用力推,还有的用手拉)你认为哪个工蚁用的力气最大?(用头顶的工蚁)(教师边演示边提问)蚂蚁的身体哪一部分不是用图形来画的'?(身体部分是用弯弯曲曲的线来画的)蚂蚁有三对足,第一对足是从头和身体连着的地方长出来的,就像人的手一样;第二对足是从腰间长出来的;第三对足是从身体下面长出来的。腿是笔直的吗?(弯弯的,前腿朝后弯,后腿朝前弯。)大家一起用力气,这群勤劳的工蚁从秋天开始搬食物,除了搬花生还可以搬什么呢?(蛋糕屑、小米粒、玉米粒、小虫子等)现在家里的食物堆得满满的,足够蚂蚁们吃上一个冬天了。

3、打开二号家。

这是一群兵蚁的家,兵蚁们正在举行宴会,它们是怎样开宴会的呢?(它们坐在桌子边,有的蚂蚁举起酒杯,有的在喝酒)坐着的蚂蚁和站着的有什么不一样呢?(坐着的蚂蚁第二段身体应该弯弯的,站着的是平平的)(演示头和第一段身体)画第二段身体老师也觉得有点难,该怎么画小蚂蚁才会坐下呢?(幼儿:该把身体横过来画)兵蚁的家里真热闹。

4、打开三号洞穴。

蚁后生小宝宝了,蚂蚁家族又添了许多新成员,蚂蚁刚出生,蚁后正在照顾小宝宝呢!蚁后、蚂蚁过冬。

我国著名学前教育学家陈鹤琴先生说过:“小孩子生来就是好动的,是以游戏为生命的。”幼儿手工活动也可以说是一种游戏活动,幼儿手工活动一般都是在看看、想想、做做、玩玩的过程中进行的。因此在开展幼儿手工活动时,也应重视游戏的重要性,在游戏中进行活动,最大限度的发挥游戏的作用

就如何将游戏与幼儿手工活动有效地结合在一起的问题,我们进行了相关的尝试与探索。

在第一次教学预设中,我采用了较为传统的形式开展,活动效果较差,经过课题组老师的交流讨论,在第二次的教学预设中,我将游戏渗入其中,尝试从以下几方面将游戏与中班手工活动《蚂蚁过冬》相结合:

1、导入环节游戏化,引发幼儿兴趣

幼儿儿手工活动要遵循兴趣性原则,以内容激起幼儿兴趣,以游戏活动满足其情感需要,激发起幼儿想象、创造,培养幼儿的审美感知,在《蚂蚁过冬》活动中,我以“蚂蚁过冬”的情境游戏导入活动,将幼儿的兴趣充分调动起来,为后续的活动打下良好的基础。

2、活动过程游戏化,促进幼儿发展

《教育指导纲要》中明确规定:幼儿园教育应尊重幼儿的人格和权力。尊重幼儿身心发展的规律和学习特点,以游戏为基本活动,寓教于各种活动之中。“新鲜好奇、好动、好玩、爱做游戏是幼儿的年龄特征,也是幼儿的天性。对幼儿来说,游戏是一种符合幼儿身心发展要求的快乐而自主的实践活动。”因此在《蚂蚁过冬》的活动过程中,我加入了模仿游戏,请幼儿根据模仿小蚂蚁搬东西,引导幼儿观察蚂蚁的动态。还加入了“蚂蚁找食物”的游戏,请幼儿当小蚂蚁,一起随音乐做动作、搬东西等,进一步巩固了幼儿的经验。

通过游戏的形式,幼儿在掌握巩固经验过程的中不会觉得枯燥,反而非常感兴趣,在做做玩玩中对蚂蚁搬东西的动态有了更进一步的了解。

小百科:蚁科(formicidae),体长2~20毫米,触角膝状,9~10节,腹部基端有1~2个结节,最易识别。营“社会生活”,有明显的多型现象,每一巢群中有雄蚁、雌蚁及生殖系统发育不全的雌性工蚁(有些种类工蚁中,有上腭发达的兵蚁)。大部分种类雌蚁及雄蚁具翅,而工蚁、兵蚁无翅。
