Like many teenagers, Ella Warren-Roberts, 14, is very creative. She makes slate jewellery, she does woodcutting, and paints in watercolours. “She always has more than one project on the go,” says her proud mother, Glenda Roberts. “And she always completes them.” “So I don’t get too stressed out on one thing, I can relax by doing another,” says Ella. This lively, cheerful teenager also really likes science but, until recently, she wasn’t able to shine at it.
