  活動準備  PPT課件、視頻一段、電子白板。  兩人合用一張動物圖片,上面有蜘蛛、蝗蟲、枯葉蝶、螳螂、青蛙、獅子、北極熊、螃蟹、貓頭鷹等。

一年級下冊,小壁虎借尾巴,請問還有哪些動物尾巴的作用

其他動物尾巴的作用:1、貓的尾巴使貓在跑跳時能保持平衡;往下落時翻過身來,四腳先著地,不至于摔傷。2、穿山甲的尾巴纏在樹上,像保險帶一樣。3、啄木鳥在豎直的樹干上站著啄食害蟲時,尾巴支撐在樹皮的裂隙中,從而能夠站穩,不至于跌落,可以說尾巴是它的“第三條腿”。4、松鼠、狐貍等長著毛茸茸粗尾巴的動物,在寒冷的時候,會把身體縮成一團,不至于受凍5、兔子的短尾巴可以在緊急情況下幫助兔子逃命。當兔子被猛獸咬住時,兔子立刻使用脫皮計,將尾巴的皮套脫下,從而贏得逃命的剎那間。
