幼兒園大班科學活動《調皮的影子》教案

出處：媽媽育兒網日期：2016-05-25 12:12:47編輯：xixi

活動目標：

1.提高身體迅速反應能力。

2.根據光源與物體的位置判斷影子的方位。

重點難點：

根據光源與物體的位置判斷影子的方位。

活動準備：

電筒、積木、代表光源、物體與影子的胸卡

活動過程：

一、帶領幼兒在教室內觀察、判斷積木影子的方向。

1.積木的影子在哪里？為什么？

2.我把光源轉到另一邊，影子應該在哪里呢？

3.光源、積木、影子的位置有什么特點？（三者在一條線上，積木在光源和影子中間）。

4.其他東西影子的位置是不是也這樣？試一試？

二、帶領幼兒到戶外玩游戲“影子影子在哪里”，繼續(xù)體驗影子的特性。

規(guī)則：3人一組，一人當光源、一人當被照射的物品，一人當影子。

光源或被照射物可以主動移動自己的位置，影子要根據光源與物品的位置快速判斷自己的位置。哨聲響起時游戲開始，當哨聲再響起時，所有人都靜止不動，此時檢查影子的位置有沒有錯誤。過段時間可以互換角色。
