Physics education needs to deal with a contrasting scenario in which new technologies of communication and access to information are becoming increasingly accessible, but the school environment is still maintained on content bases and in a rigid classroom model, centered on the teacher. Acting as a teacher in a professional technical course in electronics, from 2010 to 2014, I realized that practical activities tend to motivate and to increase the students' interest, even for complex subjects. For this reason, this work aimed to develop a similar approach in physics classes for high school in a public school, providing a dynamic learning for students. The proposed activity consisted of assembling a heartbeat sensor in the classroom, constructed with low-cost materials that, through an active teaching methodology with practical activities, allowed to develop part of the electricity program content studied in the third year of high school program. The proposal was applied in two classes of a public high school institution in the city of Uberlândia - MG, one class from regular education and the other from Young Adult Education (EJA). In practical activities it was possible to explore interdisciplinarity, addressing: electricity and electronics, light, human physiology and notions of computer programming. During the application, it was observed an improvement in the participation of students throughout the process of construction of the equipment, a relative increase in the interest about the conformity between theoretical concepts and practical results and, consequently, better fixation of the subject. Despite the small sample set, we highlight the positive results, indicating the possibility of applying similar approaches in other scenarios.
