Dr Noake had started her career as a student teacher at Lewis Girls' Schoool, working her way up the ranks to become the head in 1996.
"Dr Sue Noake devoted thirty years of her life to Lewis Girls' School, a school which she held close to her heart. In fact her name was synonymous with the school," said the school in a statement.
"She was a brilliant teacher, an excellent practioner who always sought to make science exciting and accessible to pupils of all ability."
