Resumen
The present work aimed at the accomplishment of a series of experimental practices for
the verification of the effects Seebeck and Peltier. The project was applied to the class of
the third year A of the Alfredo Nasser State College, composed of 15 students, in the city
of Britânia - GO. The Seebeck and Peltier effects are thermoelectric effects, that is,
effects that deal with the direct conversion of temperature difference to potential
difference and vice versa. Despite the richness of physics concepts involved in explaining
these effects (ranging from temperature, electric current, potential difference, electrical
and thermal conduction to semiconductors) and their importance to science and to
technological and industrial applications they are not part of of the high school
curriculum. The didactic textbooks also do not address the subject. By inserting in our
classes, the thermoelectric effects - with emphasis on experimentation - we aim to
promote a curricular update and also an opportunity to implement experimental classes
in our teaching practice, considering that in our School there are no physical laboratories.
The generated educational product consists of the text Experimental Routings on the
Seebeck and Peltier Effects, involving 10 experiments: 04 (four) related to the verification
of the Seebeck effect, 04 (four) related to the construction of thermocouples and 02 (two)
related to the Peltier effect, one of them being the construction of a mini refrigerator using
a Peltier tablet powered by a notebook. As a result of our work, we mention the excellent
opportunity to discuss in an integrated way several concepts and magnitudes, which are
often approached disconnected from each other, and also to highlight the importance of
Physics for technological applications - a relationship that seems obvious, but which,
unfortunately, is often not seen by our students. In the student part, we emphasize the
experience with the own experimental classes that were new for the absolute majority of
the students of the class and the motivation provided by the experimentation that
influenced positively in the dynamics of the theoretical classes.
