Imagine asking a classroom full of elementary school students to draw a scientist. Now try to guess how many of them would sketch a female or male scientist. In the decade that spanned 1966 to 1977, teachers across the country gave 4,800 elementary school students this exact task in what became known as the Draw-A-Scientist study. Then a researcher named David Wade Chambers analyzed the drawings. What he found, in 1983, might not surprise you: Only 28 of the children drew a female scientist -- and those students were all girls.
