On December 8, students enjoyed some holiday cheer at an Exelon STEM Day at Chicago’s Lincoln Park ZooLights, of which ComEd is a sponsor. They networked with Exelon employees over hot chocolate and cookies before taking a behind-the-scenes tour with Zoo staff to learn the many STEM elements that go into creating the light installations. Afterwards, they had the chance to explore the lights on their own with their new-found knowledge!
