In Inquiring Scientists, Inquiring Readers, science educators Jessica Fries-Gaither and Terry Shiverdecker help teachers blend literacy into elementary science instruction. This unique book will show teachers how to teach science using a variety of nonfiction text sets (such as field guides, reference books, and narrative expository texts) and replace individual lessons with a learning-cycle format (including hands-on investigations, readings, directed discussion, and problem solving). Research-based and teacher-friendly, Inquiring Scientists, Inquiring Readers shows how inquiry can engage your students in reading nonfiction texts, discussing important science concepts, and writing to both develop understanding and share information. Here are some of the book’s special features: • Eight units covering life, physical, Earth, and space science—from “Drip Drop Detectives: Exposing the Water Cycle” to “Classroom Curling: Exploring Forces and Motion” to “Beaks and Biomes: Understanding Adaptation in Migrating Organisms.” Two additional units cover the nature of science. All units have been classroom-tested for effectiveness and align with the National Science Education Standards and the Common Core State Standards for English Language Arts. • Detailed scientific background, common misconceptions associated with the content, an annotated list of the texts in the text set, safety considerations, reproducible student pages, and suggested assessments. • Authentic, inquiry-based contexts for reading, writing, and discussion through read-alouds, collaborative activities, graphic organizers, and writing prompts. Inquiring Scientists, Inquiring Readers will change the way you think about engaging your students. The authors show that it’s possible to integrate literacy into elementary-level science instruction without sacrificing quality in either area.

An investigative journalist explores our world on the brink of running out of usable water. Less than .0008 percent of the total water on Earth is fit for human consumption, but global consumption of fresh water is doubling every twenty years. Water has become perhaps our most precious commodity-a life-sustaining but increasingly rare and privatized resource. A dramatic gap exists between those who have adequate water for survival and those who don't, and tensions over water in some areas of the world hover just below open war. From Europe to Asia to Africa to America, Jeffrey Rothfeder has visited the world's hot spots, those with the least amount of water, as well as places where there is so much of it that plans are in the works to sell the excess to the highest bidder. In this compelling narrative account of our world in turmoil over water, Rothfeder describes the issues and struggles of the people on all sides of the water crisis: from the scarred survivors of bizarre water-management practices, to those who are willing to die for water to sustain their families and crops, to the scientists and leaders who are trying to set things straight. Important, provocative, and immensely readable, Every Drop for Sale explores a fascinating critical dilemma: As we run out of it, is water a fundamental right of everybody on Earth or just a product humans need that can be bought and sold like any other commodity?
