This book is developed to make the teaching and learning of history a powerful and enjoyable experience in the classroom through the study of historical mysteries. What better place to snoop around and dig through mysterious graves than in history class? This book takes ten mysterious events in history from ancient Egypt to the 21st century for students to grapple with and make their own decisions as to "Who done it?" Lessons include historical events such as "Who Killed King Tut?", "The Black Death of 1347 - Can It Come Again?" as well as an Advanced Document Analysis for the 21st Century entitled "Is the War on Terrorism Bogus?" The author focuses on a variety of active ideas and how-to-do-it brainstorms for teachers to get their students excited about history. The book also analyzes some of the major issues that have confronted humankind from ancient times through the present and into the future. [For volume 2, see ED499322.]
