The Shedd Aquarium's April Keller visits with Mrs. Diviacchi's and Ms. Fotopoulos's Mann 4th graders as part of OPEF's Global Village program. April brought some of the Shedd's animals to school and talked about what it's like to be a marine biologist. The students' study of ecosystems will culminate with a field trip to the Shedd Aquarium in May. Click here to see the photos by Mann parent Emily Opalski.
