Barbie should be put back in her box to make way for more "creative" toys such as Lego and Meccano that are traditionally given to boys, one of Britain's top women scientists says.
Dame Athene Donald, Professor of Experimental Physics at Cambridge University, believes the wrong toys are holding back girls who might otherwise go on to develop an interest in science and engineering.
She also attacked schools for taking the "lazy" option of finding work experience placements for pupils that reinforce gender stereotypes.
Speaking before her inaugural address as the new president of the British Science Association, Dame Athene said: "We need to change the way we think about boys and girls and what's appropriate for them from a very early age. Does the choice of toys matter? I believe it does.
"We introduce social constructs by stereotyping what toys boys and girls receive from the earliest age. Girls toys are typically liable to lead to passivity - combing the hair of Barbie, for instance - not building, imagining or being creative with Lego or Meccano."
