Track: High School STEM Competition
This study explores scientific concepts through the manufacture of a charger for smartphones and tablets in a state school located on the outskirts of the city of Sorocaba, in the interior of the State of São Paulo, in a region of social vulnerability. Its application took place in the shift of regular classes addressing skills of the National Common Curriculum Base - BNCC. The project includes Objective 4, belonging to the set of Sustainable Development Goals (SDGs) of the 2030 Agenda of the United Nations (UN), which deals with the promotion of quality education, ensuring inclusive and equitable and quality education, and promoting lifelong learning opportunities for all through various educational actions. It refers to the study and construction of an electronic equipment charger powered by a dynamo attached to a bicycle. In addition to the design and validation of the prototype loader, this work involves the testing and characterization of dynamo power, the design and construction of specialized test equipment, as well as the development of a handlebar-mounted case for the smartphone. The use of clean energy makes the project sustainable, besides providing health benefits through the practice of physical exercises. Still under development, the circuit is expected to meet the charging requirements of the smartphone at bicycle speeds ranging from 3 to 4 m/s of speed, inserting the school into the scientific community and providing the dissemination of scientific knowledge with actions of autonomy and protagonism.
