Mechanical engineering technicians cover part of their curriculum through a series of constructions they build with a microprocessor (Arduino), cables and led lights. Through a set of videos, technicians from different VET schools teach Primary school children how to build the circuits, create the code and eventually measure relative air humidity and ambient temperature (dry/wet bulb outdoor temperature) with common thermometers. A different VET school coordinates each activity and creates a short assessment task to be taken by all partner classes. All partner classes design the final presentation of the project and a game of Kahoot for overall assessment.
