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—Party Meltdown examines ice cubes melting at different rates; Baking Bread explores the importance of yeast; Stuck! uses a playground sliding board to explore properties of friction—the stories show how science is part of everyday life and initiate inquiry-based learning by leaving each mystery without an ending.
