The Physics TeacherThis month's cover showcases a photo from the 2017 AAPT High School Physics Photo Contest Top 100 Gallery titled "Spring is Sprung" by Michaela Emma Brooke (teacher: Daniel DuBrow) from Evanston Township High School, in Illinois. Registration for this year's contest begins March 1 at www.aapt.org. See A Tale of Two Slinkies..." by Berggren, Gandhi, Livezey, and Olf for a novel approach for using Slinkies in a physics curriculum.
