The Mechanical Engineering Graduate Student Organization sponsors occasional group activities and are noted for their cookouts. This student organization under the guidence of the Department helped renovate the Graduate Student Lounge in 2009.
For campus-wide student activities, the Graduate Student Assembly hosts several events where you can connect with other Carnegie Mellon students. GSA has a presence on Facebook and Twitter.
The department has an active engineering outreach program whose purpose is "to expose primary and secondary school students to science, technology, and engineering applications in order to increase their enthusiasm for these subjects." Our program has already visited numerous first-grade classrooms with introductory activities in engineering, provided judges for the Sigma Xi undergraduate research competition and the Pennsylvania Junior Academy of Sciences, provided lab tours for the CAST engineering program, and was involved in "Engineering Your Future," a program to encourage inner city girls to study engineering.
Plans for the future include developing additional classroom activities for all grade levels and exhibits in informal settings such as local malls. The Society for Women Engineers (SWE) is very involved in this outreach. If you are interested, please take a look at the Carnegie Mellon Chapter.
