Upon the completion of the hand hygiene project at HVTO, the students and Teaching Team took a deeper dive into the area in rural Siem Reap. On the meandering dirt roads that criss cross houses on stilts and open fields, the main modes of transportation are bikes and motorbikes, yet helmets were a rare occurrence amid all of this two-wheeling traffic. This led to the creation of a low-cost smartwatch project that reminded wearers to put their helmets on before riding off into the sunset. The hands-on nature of the project also meant an accompanying science and technology curriculum.
