Pi Day, March 14

Since 2002, the St. Louis Science Center (SLSC) and MEGSL have worked together to celebrate pi.  The celebration will be held at the Science Center during Saturday, March 14 (Pi Day 3.14) through Sunday, March 15. There will be a variety of activities for students in grades elementary through high school. Several activities and demonstrations have already been planned, but volunteers are still needed for the various stations.  Enjoy time with your MEGSL colleagues spreading the joy of Pi to the St. Louis community at the Science Center. Those willing to volunteer for a few hours may contact Gene Potter, pottergene@msn.com with subject line "Pi."

Sat. hours at SLSC: 9:30A to 4:30P

Sunday hours at SLSC: 11:00A to 4:30P.
