一天,我从学校回到家,只见孩子拿着一块小瓦片,使劲地在水泥地上磨来磨去,还不时地往瓦片上吐口水。过了一会儿,她突然兴冲冲地大叫起来:“爸爸,快来看,我的小瓦片粘在墙壁上了,小瓦片变成了小磁铁。”我走近一看,小瓦片果然粘在墙壁的垂直面上没有掉下来。当然这绝对不是小瓦片变成了小磁铁(其实是分子引力)。眼前的情形使我脑子里闪过一道灵光:应该因势利导,教孩子做一些简单的科学小实验。
One day, I came home from school and saw my child holding a small piece of tile, grinding hard on the concrete floor and spitting water on the tile from time to time. A moment later, she exclaimed in a flash of excitement: “Daddy, let’s see, my little tile stuck to the wall and the little tile turned into a little magnet.” I approached and looked at the little tile Really stuck in the vertical surface of the wall did not fall. Of course, this is definitely not a small tile into a small magnet (in fact, molecular gravitational). The immediate situation flashed a bright light in my mind: we should guide the situation, to teach children to do some simple scientific experiments.
