We present the design and construction of a didactic module that is analogous to the tunneling microscope, as a support material for the teaching of this phenomenon. We start from one of the strategies for achieving an effective teaching and learning process of physics and especially modern physics subjects is the experimentation; however, when it comes to quantum physics this kind of strategy is limited, since usually schools does not have equipments to carry out these practices, reason why it is necessary to construct a similar experimental setup that illustrates the real phenomenon and that catches students attention.
