In order to find out which of an array of materials would make the best jacket for a lighthouse keeper, Year One had to go about testing which were waterproof and which were not. They enjoyed working with a pipette to drop exact amounts of water onto the stretched fabrics and observed if the water was absorbed on not. Finally the fabric which would not allow water through it was suggested as the most suitable fabric for the task as it would keep the lighthouse keeper dry as he attended to his tasks.  June 2017
