How do tiny bugs get into oatmeal? What makes children look like— or different from— their parents? Where do rotten apples go after they fall off the tree? By presenting everyday mysteries like these, this book will motivate your students to carry out hands-on science investigations and actually care about the results. These 20 open-ended mysteries focus exclusively on biological science, including botany, human physiology, zoology, and health. The stories come with lists of science concepts to explore, grade-appropriate strategies for using them, and explanations of how the lessons align with national standards. They also relieve you of the tiring work of designing inquiry lessons from scratch. “ What makes this book so special is the unique way science is integrated into the story line, using characters and situations children can easily identify with.” — Page Keeley, author of the NSTA Press series Uncovering Student Ideas in Science
