Abstract

It is quantum mechanics that do to microscopic phenomenon about that body of theory that do to macroscopic phenomenon is classical dynamics. Students touch first time in physicsⅡ and chemistryⅡ that is third-year student process in high school about the basic item of quantum dynamics belonging to quantity theory of modern physics. The role of Science teacher is to help all students approach to the science more easily. Scientific research ability is reared best though do to do activity that analyze science activity that scientist behaves and draw research urea and make students experience directly and think this routinely. That is, it can be very difficult work that teach the microscopic world to the students, who is familiar with observing and objectificate with their eyes. PhysicsⅡ's atom model unit and ChemistryⅡ's atom models and electronic configuration unit are depended on cramming method studying. Introduction to the quantum theory like Flank constant, wave theory, particle theory, and so on, are taught, but other nature's changes are not determined. Therefore, the students remember the modern physics as a difficult chapter. However, it is a difficulty for the college students as they learn the quantum mechanics right after the classical mechanics in their freshmen. It's something like wandering in an unfamiliar area. Bohr's atom model can explain well about the regularity of spectrum or absorption and release of photon that was not able to do with Rutherford's atom model. However, there's following problems with Bohr's atom model. It works well with the hydrogen atom with only one electron orbit, but other atom with many electrons, their orbits and energy level cannot be explained. Therefore, it is to be explained that there can be electrons with a possibility, rather than there's a certain orbit of electrons around the atomics nucleus. New atom model is presented with the quantum mechanics, which says that there is electron cloud around the atomics nucleus with the probability distribution of electrons rather than the orbit of electrons. We will compare the vibration mode of a percussion instrument and the probability distribution of quantum mechanism in the purpose of easier explanation to the students about the electron cloud, the probability distribution of electrons Students do not think about the quantum mechanics when learning the physics and natural science, and it doesn't matter if they don't know. However, I hope that it can be helpful for the desire of knowing the true state of the nature.
