“……蚯蚓的再生能力很强,把一条蚯蚓切为两段,放回土中,没几天会变成两条完整的蚯蚓……”我讲着,小朋友一个个瞪大了眼睛,流露出惊奇的目光。此时,“小问号”王潇枫举起了手:“老师,如果把蚯蚓切成三段,能不能变成三条蚯蚓?如果切成四段、五段呢?”“哗”,活动室里像水开了的锅,大家七嘴八舌地议论起来。刚刚听到王潇枫小朋友的提问,我也是一愣,尽管我课前做了准备,了解了蚯蚓的一些习性,如再生能力强等情况,但是从未想过,把蚯蚓切成三段或更多段,它是否能成为三条或更多条蚯蚓。我觉得王潇枫小朋友提的问题很有价值,是一种发散性思维的成果,于是我说:“这个问题提得好,老师一时也回答不出,要靠大家一起动脑筋解答。”这一下又热闹起来了,殷丽雯小朋友说:“去翻《十万 “... earthworms are very capable of regenerating earthworms, cutting them into two sections and putting them back into the soil.

I think Wang Xiaofeng children mentioned the problem is very valuable, is a result of divergent thinking, so I said: “This question is well, the teacher can not answer for a moment, rely on everyone to use their brains to answer.” Lively, Yin Liwen said: “go to turn” one hundred thousand
