The present work aims link the approaches of technology to the teaching process of Physics in Secondary Education using as a didactic tool a School Technological Activity (STA).For this purpose, it was designed a STA test through the construction of a clock, where different physics conceptual elements will be studied, and the technological process that involves an artifact. All this in order to provide an attractive proposal that links in a cross-cutting way the technology to other knowledge areas. The adopted methodology for the present study is established from the qualitative approach, which produces findings but not through statistical and quantitative procedures; all of the above will be made through the observations of participants in physics class. In the interpretation of data, we seek answers to discover knowledge that will enable us to increase the comprehension about occurrence of this phenomenon.
