The present article comes from an illustration of the etymology of the word constructivism - to sow together - and then gather the seeds that will be put at the pupils disposal throughout the courses for the development of Physics teachers. Among them there are arguments in favor of a sustainable version of Constructivism, recognizing the critics of epistemological, psychological or even pedagogical origin, to a few aspects of versions that have been circulated by researchers of education in science, in the last years. With the commitment of not being limited to criticism and in light of the complexity of educational systems about which the debate about Constructivism takes place, the pedagogical version proposed in this work integrates a vision of reality closer to that acceptable by the community of researchers and professors of Physics. There is valuable work in constructivist teaching of scientific knowledge that the community of researchers in education of Physics has carried out for more than two decades in Brazil as well as in other countries.
