　　蠶寶寶

　　科學(xué)課上老師讓我們回家養(yǎng)蠶，要求要從開始就要做好記錄，看它的生長情況發(fā)生的變化，回家后我讓我媽弄了一些蠶種子。

　　蠶的卵比小米粒大些，白色的有點黑，粘在一片紙的上面。過了兩天，卵殼內(nèi)出現(xiàn)了一個小黑點，越來越明顯，到后來竟是一只小小的蟲子從卵殼里爬出來了，我知道這就是一只小蠶了。小蠶的身體細(xì)小，呈黑褐色，全身滿生著毛毛，形態(tài)象螞蟻，老師說叫做蟻蠶，毛毛叫剛毛。

　　蟻蠶就能吃桑葉，生長的很快，它的身體中部變青綠色，剛毛變少了，隨著身體的不斷增大，體色逐漸變淡，青色里面有白色。

　　第4天開始，幼蟲不吃桑葉了，吐了一些絲狀的物質(zhì)，把肚子和尾巴纏在蠶葉上，一動不動，我以為它在吐絲做繭，老師說它在蛻皮。果然，經(jīng)過一晝夜時間，即脫去舊皮，換上新衣服。

　　剛脫去皮的蠶又開始吃食物了，繼續(xù)生長，到了一定程度，大約6天又要脫皮。這次我知道它又要蛻皮，就不喂它了，等它蛻完皮再開始為它桑葉吃。這樣一共蛻了4次皮，每次蛻皮后吃的食物特別多。老師說它已經(jīng)長到五歲了，就要吐絲做繭了，讓我給它做個小房子。五歲的蠶寶寶身體前邊半透明狀態(tài)，也不吃桑葉了，把頭抬得很高，左右搖擺，像是在跳舞，把口里的一根細(xì)細(xì)的長絲有規(guī)律地織在小房子里。3天以后，一只白色的繭就做成了，我的蠶寶寶就在里面睡著了。
