    周記600字-驚喜連連來

    發布時間:2019-07-02 09:07 編輯:涪陽小學武則天老

      同學們,莫比烏斯圈知道不。一定不知道了吧,如果你問我們班同學,他一定會喜形于色,滔滔不絕地說給你聽。如果你還不明白,別急,他會準備一張紙,一邊說一邊做給你看,就是把一張紙條的一端扭轉180度角再和另一端粘接起來,這就是“莫比烏斯圈”。

      今天,老師給我們上了一堂有趣的實驗課,其中就給我們介紹了莫比烏斯圈的兩大神奇之處,讓我們是驚喜連連來。下面就聽我慢慢地說吧,它一定會使你大吃一驚。

      莫比烏斯圈的一大神奇之處是在于它只有一個面的,不像其他紙,有兩個面。不信,隨便你自己拿一張普通的紙,不管你怎么折都是兩個面,或許還有更多的面。當老師講到這時,大家都迷惑不解,自言自語說:“不就是扭轉了180度嘛,怎么會只有一個面。” 周老師好像猜到大家的心思,就提前拿了一瓶紅墨水和一支毛筆,當場就演示給我們看,是不是一個面,我們連聲叫好。周老師揮舞著毛筆在莫比烏斯圈的一面畫著中線,只見停也不停在畫,最后還是順利的到達了起點處,讓我們見證了莫比烏斯圈的一大神奇之處。

      莫比烏斯圈它不僅是“一個面的紙”,它還有“一刀變大,兩刀變兩” 神奇之處,這就是它的第二大神奇之處。

      當你沿著莫比烏斯圈的中線用剪刀“咔嚓,咔嚓”的剪,你會發現當你剪完最后一刀時,這圈會比原來的圈大一倍。這就是“一刀變大”那“兩刀變兩”呢?別急,慢慢來,我們又沿著莫比烏斯圈的中線用剪刀“咔嚓,咔嚓”的剪,你又會發現當你剪完最后一刀時,原來的大圈會變成一模一樣兩個連環圈。神奇吧,當我們看完兩次的最后一刀時,別提心里有多么激動。

      這次實驗就在我們的驚訝聲中落下了帷幕。這次實驗也告訴我們:我們要開發智慧的頭腦,動起敏捷的雙手,讓我們去創造,去開發更多給我們帶來快樂的源泉。
