Primary Science Applications

For primary science, all the investigations needed can centre around the simple electro-magnet. This can be made by winding about 20-40 tight, neat turns around an iron nail and connecting the ends of this coil to 1 or 2 torch-sized 1.5v batteries. Once used, the nail may retain some magnetism, even when the current is switched off
