科学课上,老师教我们做了许多有趣的实验,其中,印象最深的是“摩擦起电”。令我们充满好奇的小实验开始了。首先,陈老师拿起梳子,在动物皮毛上轻轻擦了三下,然后,把梳子放到一个女生的头发上方大约二三厘米处,“咦,没什么反应啊。”我们都不解了。陈老师立刻为我们解释起来,哦,原来是陈老师跟我们开了一个小小的玩笑。接着,陈老师又重新用力摩擦起来。在摩擦的过程中,我们隐隐看到了如星星般的小亮光。摩擦了近两分钟后,老师又拿起梳子走到那个女生旁边,结果和第一次大为不同。这次,一根根头发就像着了魔一样,跟着梳子跑,梳子到哪儿,它 Science class, the teacher taught us to do a lot of interesting experiments, of which, the deepest impression is “friction electrification ”. The little experiment we got curious began. First of all, Chen picked up the comb and rubbed lightly on the animal fur for three times. Then, put the comb around two or three centimeters above the hair of a girl, “No, no response.” We do not understand It’s Teacher Chen immediately explained to us, oh, it turned out that Professor Chen had a small joke with us. Then, teacher Chen friction with friction again. In the process of friction, we faintly saw a small light like a star. Nearly two minutes after rubbing, the teacher picked up the comb and walked next to the girl, and the result was very different from the first one. This time, a root hair is like a devil, run with the comb, where is the comb, where is it?
