Science Science Discovery Day Stage 3 students from Muswellbrook South recently won the Coal and Allied Science and Engineering Challenge, competing against schools from across the Upper Hunter. The Challenge is a set of fun and competitive activities involving the principles of science, engineering and technology. Students explored scientific principles for themselves rather than being guided to a predetermined answer. Throughout the Challenge teams were asked to design motorised crafts, build bridges and crack codes to solve various problems. © Muswellbrook South Public School 2007
