The excessive exposure to ultraviolet radiation, natural or artificial, is a public health concern. For this reason, it is important that, from an early age, children and teenagers gain awareness of this problem. By not being visible to the human eye, ultraviolet radiation is an abstract concept and difficult to understand, although its short-term effects may be visible. In this project, we proposed the use of the Arduino platform to measure and verify the effect of various sunblocks, making it possible to materialize the concept of UV radiation. Thus, it was the aim of this project to study the influence of the Arduino platform use, associated with an ultraviolet radiation sensor, in the understanding of this type of radiation and in the awareness to the artificial sources of UV radiation used in the daily life of many people. This project was carried out with a group of students from the ninth grade, from a school in Porto, Portugal. The methodology used allowed the students to develop interdisciplinary skills, namely in the areas of natural sciences, programming, and mathematics, providing them with useful lifelong tools.
