Abstract: The wave-particle duality of micro particles could lead to many effects that are hard to be understood by daily experiences, thus beginners have many difficulties and easily fall into confusion in learning the basic concepts of the quantum physics. The quantum effects are too abstract to be understood for a beginner because the electrons and atoms in microphysics can not be seen directly and hard to imagine. In teaching atomic physics and quantum physics, one can magnify the quantum effects to the macro world to show the strong conflicts between the peculiar quantum effects and people＇ s daily experiences. In this paper some examples are introduced to show this technique, which will be helpful in understanding the basic concepts. The quantum effects are magnified to the macro objects by artificially change the Planck constant,and therefore lead to some interesting results.

Key words: quantum effects, atomic physics, teaching
