  • 大班科学《弹性》说课稿

    大班科学《弹性》说课稿

    幼儿天生具有强烈的好奇心,对周围事物的探索和求知欲望也特别强,因此,新纲要强调“科学教育应密切联系幼儿的实际生活进行,利用身边的事物和现象作为科学探索的现象”。日常生活中,幼儿已接触很多弹性玩具(皮球、拉力器、蹦蹦床),对它们十分感兴趣,但幼儿对“弹性”的认识仅是一些感性经验,对弹性玩具和用品的一些特性,还不是很了解,,因此,我设计了系列活动,“有趣的弹性玩具”、“弹力的大小”、“制作弹力小玩具”让幼儿通过亲身经历探究,实验和操作感知弹性的特点,获取有关弹性的科学经验。激发幼儿探索科学现象的兴趣,培养其关心周围事物的习惯。同时,本教材除了源于幼儿身边熟悉的事物能引起幼儿的共鸣,产生学习探索欲望外,还有利于幼儿在动手操作中学习掌握观察、操作、记录等科学方法,激发幼儿对科学活动的探索兴趣。
