Project Exploration's All Girls Expedition is an intensive two-week classroom and field work experience. For the past three years it has been run in partnership with Young Women’s Leadership Charter School and twenty girls have participated.

The expedition begins in Chicago with intensive classroom sessions where girls learn practical geology, biology, evaluation, and field skills. Then the team spends one week working in the field alongside scientists. In past expeditions, the team has traveled to Wyoming, Montana, and Puerto Rico.
