This is a proposal of sequence of activities to teach fundamental physics concepts, such as time, energy, and field. We start from the problematic that usually these concepts are taught based on a mathematical application or an equation without taking into account its epistemological construction. We propose to develop a process of explanation through simple interactions from events that can be seen on a daily, for example collision between a Ping-Pong ball and a thin of balsa wood sheet that completely absorbs its kinetic energy, or a Ping-Pong ball and a glass sheet etc. In addition, the role of materials deformation as one of the main causes of energy transformation is analyzed. Finally, it is proposed that this activity be carried out from primary in parallel with discovery and description of the matter properties, in order to deal effectively with the first preconceptions that the child handles with respect to these concepts.
