Small wastepaper is met " dance " , do you believe? If be not believed, look on the classroom that will follow me one case to us " the report since attrition " small experiment!
小小的纸屑会“跳舞”，你相信吗？如果不信，就来跟我一起到我们的课堂上看看“摩擦起电”的小实验吧！
The data that we need to prepare has: Composition paper of a piece of rule of a model, A4.
我们需要准备的材料有：一把塑尺子、一张A4纸。
Attend class, the teacher tells us smilingly: "Today, the little test that we should do is ' the report since attrition ' ! " hear this news, I ground of too impatient to wait should begin a test!
一上课，老师笑容满面地告诉我们：“今天，我们要做的小实验是‘摩擦起电’！”一听到这个消息，我便迫不及待地要开始实验了！
Above all, it is an A4 paper lacerate, go up as the class " give a talking-to pulls give a talking-to " sound as one falls, not a little while, we rip A4 paper have one's body smashed to pieces, turned one caboodle into small wastepaper, caboodle resembles a small mountain together. Next, we want attrition rule to let it be taken electrostatic, I take straightedge, exert all one's strength the ground allows the attrition on its head in me. Some classmates are taking red scarf to chafe on the hair, look like a small red cap; Two arms fold some classmates together, mutual attrition; Still some classmates take rule to be in directly chafe on the head of the desk together. Everybody is very dedicated exert to one's utmost. After a few minutes pass, of hemp of the hemp on the head, begin to send very hot, I knew to witness miraculous hour namely next -- let small wastepaper " dance " . My screen lives breath, pray silently, must succeed! Finally, I have on one cautiously to extend toward wastepaper with straightedge, motionless before wastepaper " vivid " rise, my rule controls shift, wastepaper also controls shift accordingly, seem to jumping " dance for two people " . "Too magical " I can't help giving out deep feeling.
首先，是把A4纸撕碎，随着班上“呲拉呲拉”的声音此起彼伏，不一会儿，我们就把A4纸撕得粉身碎骨，变成了一堆小纸屑，堆在一起就像一座小小的山。然后，我们要摩擦尺子让它带上静电，我把直尺拿起来，使劲地让它在我的头上摩擦。有的同学拿着红领巾在头发上摩擦，看起来像个小红帽；有的同学两只手臂叠在一起，互相摩擦；还有的同学直接拿起尺子在同桌的头上摩擦。大家都十分专注卖力。几分钟过后，头上麻麻的，开始发烫，我知道接下来就是见证奇迹的时刻了——让小小的纸屑“跳舞”。我屏住呼吸，默默祈祷，一定要成功啊！最后，我小心翼翼地用直尺往纸屑有上一伸，原来一动不动的纸屑就“活”了起来，我的尺子左右移动，纸屑也跟着左右移动，就好像在跳“双人舞”。“太神奇了”我不禁发出感慨。
Why can wastepaper dance? Among them mystery passes attrition with plastic feet and hair namely generation is electrostatic, so ability can have this one magical appearance.
纸屑为什么会跳舞呢？其中的奥秘就是与塑料尺和头发通过摩擦产生静电，所以才会有这一神奇的现象。
Pass this test, I understood: Want you only attentive observation, the life is met wonderful immensity.
通过这个实验，我明白了：只要你细心观察，生活就会精彩无边。
