What are the odds that a meteor will hit your house? Do you actually get more sunlight from Daylight Saving Time? Where do puddles go? 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 19 open-ended mysteries focus exclusively on Earth and space science, including astronomy, energy, climate, and geology. 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.
