In its program of studies for preschool level, the Secretary of Public Education of Mexico promoted development of four standards of science: Scientific knowledge, applications of scientific knowledge and technology, skills associated to science, and attitudes associated to science. However, to develop this skills and reach out the standards there are some problems; one of them is lack of specific syllabus that allow to the teachers since a concept develop the skills needed to reach out the four standards in science. In this paper we shows the results of use physics concepts (specifically electricity) to build skills aimed to reach the standards of science in children of preschool level. We implemented an inquiry cycle that include generation questions, abstract conceptualization, demonstrative experiments, handling of experimental kits and a link of the experience with the real world, all around of concept of electric charge. We find finalizing the cycle that the kids achieved acquisition of a basic science vocabulary, developing of a greater capacity to interpret and represent natural phenomena and link of scientific knowledge with their environment, skills request to reach out standards of science in preschool students in Mexico.
