The present work deals with the insertion of experimental practice with simple electrical circuits using easily accessible materials. Several studies presented students' difficulties in understand physics concepts. Other researches point in teaching difficulties, due to the abstraction of content, there are also texts with critics, related to the traditional way of teaching, which is often centered on the excessive resolution of questions, fundamentally theoretical. In view of this scenario, which is still very common in schools, the teaching of Physics built with experimental activities has stood out for promoting greater motivation for students, in addition to bringing evidence of learning. From this perspective, a Teaching Sequence was created to help teachers in teaching electrodynamics and the application of experimental activities in high school. The objective of this work is to present the use of LED`s (light emitting diode), associated with materials that are easy to find in everyday life, and that can be used as simple electrical circuits. And at the same time, the proposed material encourages experimental practice in the teaching of Physics. For this, sets were built using simple materials and the teacher's wish. As well as experimental practices were also prepared with scripts for each theme. Most of the activities involve the use of LEDs, where students have the possibility to study the phenomena of conducting electricity, electric current, voltage, resistance and several other topics, aimed at exploring basic electrodynamics.
