Sophomore year of high school I got placed into a chem lab group with 3 other boys. One of them automatically assumed that because I was a girl, my opinion was not valid. He ignored me the majority of the time we had to work in the lab. But the two other boys in the group soon recognized that I knew all the answers and stood up for me. I urge all girls to stand up for themselves and all boys to stand up for girls who are negatively affected by the gender stereotypes that still exist today.
