An easy-to-make flip book covering an entire lunar cycle, as seen from the northern hemisphere.
Simply print or glue the template onto thin card stock, cut along the lines, stack the pages in order, and staple the left side. Alternatively, if the stack is too thick for staples, you could use a wide rubber band to bind the left-hand side of the pages.
Unlike many other lunar phase flip books, this one covers all 28 days of a lunar cycle. It also features libration, which is an apparent "wobble" in the appearance of the Moon and its phases caused by its non-circular orbit around the Earth.
