The purpose of this assessment probe is to elicit students’ ideas about the water cycle. The probe is designed to find out what students think a representation of the water cycle should include to show evaporation and transpiration. This probe is best used with grades 3–8, and can be extended by using the formative assessment classroom technique of annotated drawing. A materials list, teacher background information, references, assessment, and outcomes are provided. This book selection includes the Table of Contents, Foreword, Preface, Acknowledgments, About the Authors, Introduction, and Index.
