我在设计原子的核式结构模型一课时,发现对于为什么要进行α粒子散射实验和实验结果说明什么问题时,感觉学生难以理解,于是设计了一个用纸球砸彩蛋的轻松小实验,成功的解决了这样难点,并且借助与iPad这种全新的教学手段很好的模拟α粒子散射实验,用交互功能很好的讨论了核式结构模型.[课程标准]让学生了解人类探索原子结构的历史以及有关经典实验,知道α粒子散射实验,了解原子核式结构模型. When I was designing the nuclear atomic structure model of the atom for a class, I found it difficult for students to comprehend why the α-particle scattering experiment and the experimental result should explain why. So I designed an easy experiment to smash the egg with a paper ball. Solve such difficulties, and interact well with the nuclear particle model with good simulations of α-particle scattering experiments with the brand-new teaching methods of iPad. [Course standard] Enable students to understand the history of human exploration of atomic structures As well as the classic experiment, we know the experiment of α particle scattering to understand the atomic structure model.
