Abstract: This paper is set by elaboration and implementation of an educational product in a technical degree course in Dourados-MS city. Two research questions guided the study and give meaning as reference for mounting a Didactic Sequential built in six moments involving investigative activities, both of them propitiated the concepts learning of sound and electromagnetic waves, by expositive classes and doing Investigative Experimental Activities (IEA), focused on mounting and exploration of electrical circuits. At first gone identify the previous knowledges of the students about waves, in the second moment was worked the theory of electromagnetic waves, so as the setting-up of the problem and also the hypothesis registry. In the third moment the students done the first IEA meaning to answer the problem question of the previous moment, in the fourth moment were done the exploration of the theory of sound waves, as well the doing of second problem question, and hypothesis registry. In the fifth moment the students developed the second IEA with the wave generator electrical circuit for trying to answer the problem question done in the moment before, and in the sixth moment, the last one, and the students done write report and presented as a seminary. All these activities were worked in a totalized 24 class time, being each moment of 4 class time. Many resources were used for resulted collect, as audio record, movie, and questionnaires application, hypothesis registry and written reports doing by the students. These data were analyzed in three stages, were the first one presents the activities done in each moment with details, the second one does the contextualization of spoken records in audios and movies, and the third is the analysis of answer gotten with the questionnaire, the registered hypothesis, and written reports. With this, were able to conclude that the Didactic Sequential and the wave generator electrical circuit contributed in a positive way for the students’ concepts evolution.

Abstract: Modern and Contemporary Physics can be approached in High School, as suggested by numerous researches in this respect, as long as its topics are contextualized with the daily life of the students. Taking into account this perspective was developed an educational product that is characterized as a Didactic Sequence to work Modern Physics contents in Teaching through the approach of the operation of the device LED (light emitting diode). This sequence was divided into ten moments where the teacher can use different approaches such as lectures, computer simulation and demonstration experiment with investigative character. The educational product was applied in a third year high school class of Álvaro Martins dos Santos State School, located in the municipality of Laguna Carapã - MS. 19 students participated in the class. At the first moment, we tried to identify the students' previous knowledge about the concepts to be approached. In the second moment the concept of waves was approached theoretically. The third moment is characterized by the presentation of the computational simulation and the activity that follows it. The fourth and fifth moments were the theoretical approach of the concepts of electromagnetic radiation, ionizing and non-ionizing radiation, LED, Bohr's atomic model, energy bands and semiconductor doping. At the sixth moment the demonstration experiment was carried out with an investigative character. The seventh and eighth times were characterized by the approach of electrical characteristics, colors and LED applications. In the ninth and tenth moments, respectively, the application of the second questionnaire to verify the acquired concepts and the production of the written report occurred. The resources used for the data collection were questionnaires, a diagnosis and one at the end of the presentation of the classes, activity related to computer simulation, written report related to the demonstration experiment with investigative character, final written report and audio recording of the classes. During the activities the students were given active participation through discussions of the concepts involved, hypothesis collection and argumentation of the facts. The proposed Didactic Sequence was applicable to high school students and analyzing the results obtained through the data collection instruments, it can be concluded that it contributed positively to the learning of new concepts of Physics related to Modern Physics.
