"Their eyes light up, they ask good questions, they can explain the concept to other students, and they relate what they learn in class to what happens in the world." That's how students respond to the project-based, cooperative-inquiry Earth, life, environmental, and physical science lessons this book fully describes. Theoretical discussion of constructivist learning introduces the detailed lessons, many of which hinge on reproducible handouts to present a puzzling scientific phenomenon for students to investigate. Aligns to Common Core state standards. Grades 5–12. Index. Suggested resources. Illustrated
