    5th Grade Trip

    This year we will resume the tradition of our fifth grade class attending an overnight trip to Lake Placid. We are very excited to further explore the fifth grade Inquiry Unit on the Olympics by visiting the Olympic sites, having a chance to learn how to curl and visiting the Olympic Museum. This trip is the culminating experience for our students in Lower School and prepares them for their next step in Middle School.
