``Promoting scientific literacy through song`` is how these clever folks describe this fabulous tool. We don`t teach science in grammar school, because teaching meaningful science requires certain language and mathematical mastery. Yet scientific memorization is important, and this is the tool. You`ll be singing ``Oh Bacteria`` instead of ``Oh Suzanna`` and ``Cold Blooded Vertebrates`` instead of ``When Johnny Comes Marching Home.`` This will be worth entertaining the grandparents at Thanksgiving. Includes CD, text and workbook.
