Science and Christian Faith is a senior seminar course designed for biology and chemistry majors. The course revisits the three FYS course questions: Who am I? Who are my neighbors? How will we live in the world? Our thoughtful examination of these three questions will draw on knowledge gained from your biology and chemistry courses, but also integrates broadly with your liberal arts education (religion, philosophy, etc.) as we explore questions of origins, creation care, and bioethics and through the lens of Christian faith and theology. The readings, written assignments, oral presentations, and discussions will lead us to consider how God calls us, as scientists and people of faith, to be agents of redemption in our world. Prerequisites: senior biology or chemistry major. Junior biology or chemistry majors who cannot take this course during their senior year may request permission from their advisor who will consult with the department chairs to register. (3 credits) (Cross-referenced in chemistry)
