PolyToday: First-grade philatelists

The Class of 2031 recently embarked on their first field trip of the year - to the Caltech Post Office. The budding philatelists recently designed their own stamps during their dedicated STEAM (Science, Technology, Engineering, Art and Math) time. Yesterday, the first-graders walked to the Post Office to mail postcards to their fifth-grade reading buddies and enjoyed seeing their stamps on display. Students were given a short tour of the behind the scenes at the Post Office.
The stamps are on display at the Caltech Post Office over the next few weeks.
