Book excerpt: This reader-friendly text is solidly grounded on the three legged stool of constructivist theory, science content standards and practical applications. In this book for both experienced and novice teachers of elementary and middle school science, the authors connect constructivist compatible theory with practical teaching strategies and activities. Special features include original activities, a rich resource list for the constructivist science teacher, as well as strategies for working with special education students and English language learners (ELLs) in science. Classic and new ideas for student activities include "Big Science" activities such as tissue paper hot air balloons, cardboard boats and catenary arch projects developed by Edward Ebert. Discussion questions for teacher study groups close each chapter.
