草尖上的追逐,是一场青春的演出。那天的课外自主活动,班长陆姗姗抱着一盆芦荟给我们阐明物理实验主题后,笑着点了名字:“夏林,你先来。任何一种物体都有磁场,你对植物唱歌或者说话,当磁场有感应时,它就会通过连通在叶子上的电线上的电流表感应出来……大家都可以来试试!” The chase on the grass is a youthful performance. The extracurricular activities that day, squad leader Lu Shanshan holding aloe vera to us to clarify the subject of physical experiment, smiled and clicked on the name: “Xia Lin, you first come in. Any kind of object has a magnetic field, you sing to plants Or, when the magnetic field is sensed, it will be sensed by the ammeter connected to the wire on the leaf ... Everybody can try! ”"
