Book excerpt: In the fourth book of this award-winning series, author Richard Konicek-Moran explores 15 new mysteries children and adults encounter in their daily lives. Relating the mysteries to experiences familiar to elementary and middle school students, the stories show how science is part of everyday life and initiate inquiry-based learning by leaving each mystery without an ending. Students identify the problem to be solved, formulate questions, form hypotheses, test their ideas, and come up with possible explanations.
