CIERA Postdoctoral Fellows Laura Trouille and Laura Fissel led a new ‘Mission to Space’ workshop during Expanding your Horizons on March 28th, 2015. Expanding your Horizons is a day-long STEM event for 6th-8th grade girls. Most of the over 200 participants were Chicago Public School students. Throughout the day the girls participated in hands-on STEM activities with women in STEM mentors. In the CIERA workshop, the girls designed their own Mission to Europa, Io, or Mars using WorldWide Telescope, including designing their own rover to best address their science questions. Northwestern undergraduate student Casey Norlin collaborated with Laura Trouille on creating the workshop materials. They had a blast!
