This high school physical science lesson has the following learning goals for students: design and perform an investigation to assess the physical and chemical properties of a set of metals; formulate the investigation design to determine the number of metals present; evaluate their investigation results, compare their results with those listed in scientific manuals, and justify their interpretations; and argue and defend their outcomes through a debate with other teams. A materials list, teacher background information, assessments, outcomes, and suggestions for differentiation are provided. This book selection includes the Table of Contents, Preface, Acknowledgments, About the Authors, and Index.
