The 7th-grade life science class had the privilege of having Mrs. Kelly Bergen come and present her expertise on the heart. She was able to show the students both old and new pacemakers and the technology that has affected the electrophysiology of the heart. She taught on the different careers in the cardiac field and how each educational experience is unique to its field of study. She finished the presentation off by dissecting a heart and showing the students first hand the anatomy and physiology of the organ.  Mrs. Bergen has two students at GCS, Zoe a 9th-grade student and Zach a 7th-grade student. Gallery
