The students were at the University to attend Women in Science Day Nov. 7, during which about 100 female high school students from six different St. Louis city schools toured the campuses, participated in hands-on activities and got advice on careers in science. The day was hosted by the Young Scientist Program and the Association for Women in Science and partially funded by a Midwest Rural-Urban Girls Collaborative Mini-Grant Award.
