Technological advances brought changes in several social spheres, including education. The use of Information and Communication Technologies (ICT) in teaching, implies a new way of conceiving or knowledge through resources strongly present in the students' daily lives. Authors such as Cunha (2009), Kenski (2012), Libâneo (2013), Moran (2012), Prensky (2012), Silva (2018), Tajra (2001) and Valente (2005) argue that education should continue as a global evolution and develop new learning tactics respecting the characteristics of each generation. The cell phone is a common ICT for everyone, and the current generation of students, having access to this tool since the early years, has a great command of its functions. Therefore, it becomes feasible to use it as a didactic resource that facilitates learning in the teaching of physics, whether to reproduce, mediate or conclude a certain theme. Based on this assumption, this study brings or reports an experience of applying a didactic proposal, developed with the intention of using or using a cell phone in Physics classes as an auxiliary tool in a 2nd year class of regular high school, belonging to a state school, located in the municipality of Alagoa Nova - PB. An application and a game were used to display the contents related to the study of the Wave. At the end of the proposal application, you can use the same alarm clock of great interest to the students, as it is related to a technological tool with the studied physical content.
