A great workshop was recently held at Kambrya College, Berwick.  The teachers reported finding the day valuable PD. The students said it was a ‘fun day’.

Activities included tensile strength testing of supermarket bag plastics.  Testing found some bags to be weak with little elasticity, while others only broke after stretching to six times their length under considerable load.  Students built battery powered propeller driven cars from simple materials later using them to investigate the effects of placing batteries in parallel and series.
