A GRANDAD who happens to be an expert in the field of chemistry has been teaching his granddaughter science using objects found in the home. Oxford pensioner, Bernard Dagnall, 76, has never been a professional teacher, but used his experience working as a chemist to school his nine-year-old granddaughter Ella on the topic. Ella attends Holly Spring Primary School in Bracknell and spent many months learning from home due to the pandemic. To help take the huge task of home schooling off the shoulders of Ella's mother, Mr Dagnall took the reins, teaching Ella science remotely for an hour every morning via a video call.
