In this DeCal, students will discover the answers to these questions through a biweekly lecture series accompanied by weekly lab worksessions. Students in this course will advance their scientific and engineering knowledge while developing communication and laboratory skills. There will be one final paper and a strict attendance policy which is outlined in the syllabus.
