幼兒園大班科學(xué)活動(dòng)《爬線精靈》教案及反思

出處：媽媽育兒網(wǎng)日期：2016-03-29 13:10:26編輯：xixi

活動(dòng)目標(biāo)：

1.繼續(xù)探索橡皮筋和鋁線的特性。

2.熟練地操作游戲材料。

重點(diǎn)難點(diǎn)：

探索橡皮筋和鋁線的特性，熟練地操作游戲材料。

活動(dòng)準(zhǔn)備：

幼兒用書、玩具卡

活動(dòng)過程：

一、請(qǐng)幼兒閱讀幼兒用書，激發(fā)他們的探索興趣。

1.啄木鳥是怎么啄樹洞的？

2.你們坐過旋轉(zhuǎn)木馬嗎？

3.做一個(gè)旋轉(zhuǎn)秋千需要什么材料？

二、將幼兒分成2人一組，請(qǐng)他們共同準(zhǔn)備游戲材料。

1.根據(jù)書上的說明，請(qǐng)分工做好游戲玩具。做完之后玩一玩。

2.怎么固定吸管？

三、請(qǐng)幼兒2人一組玩游戲，引導(dǎo)他們有重點(diǎn)地進(jìn)行探究。

1.啄木鳥嘟嘟嘟。

2.旋轉(zhuǎn)秋千。

3.用粗筆和細(xì)筆卷出不同大小的圈，圖卡不落時(shí)的速度會(huì)一樣嗎？

4.如果兩端的圖卡一個(gè)輕一個(gè)重，下落時(shí)會(huì)怎么樣呢？

四、老師有針對(duì)幼兒集中感興趣的問題組織討論：

1.為什么放松橡皮筋時(shí)，啄木鳥的爬行方式會(huì)不一樣？

2.用粗筆卷出的圈和用細(xì)筆卷出的圈相比，圖卡在哪一種圈上下落得快些？它是怎么落下來的？為什么會(huì)這樣？

活動(dòng)反思：

在此活動(dòng)中，幼兒興趣較濃，情緒高漲。有的幼兒能很快制作出爬線玩具，有的呢，則還需要同伴和老師的幫助。結(jié)束后，幼兒每個(gè)人手上都有了一個(gè)爬線玩具，幼兒在探索方面還不夠，因?yàn)橛械挠變簺]有帶來鋁線。需要下來后，再提供更多不同各類的線讓幼兒探索。
