Our Pittsburgh History students spent a day in Old Allegheny City! They toured the Allegheny Observatory and learned about its rich heritage and the many advances in science and technology that have taken place there. A walking tour of Manchester, old "Millionaire’s Row", and Lake Elizabeth in Allegheny Commons Park gave the students a vision of what life was like during the industrial age. by @setonlasalle

Student Council is excited to announce our first-ever Donation War! Next week, during Spirit Week, each grade will compete to see who can collect the most points while helping support those in need in our community. Each grade has been assigned specific items to collect and donate. All donations must be new and unused. Large collection boxes for each grade will be located in the Auditorium lobby. The winning grade will receive a special movie day reward! Every donation counts. Bring in what you can, help your grade earn points, and most importantly, help us make a difference in our community! by @setonlasalle
