The lessons contained in this chapter highlight collaborating to improve teacher STEM preparation. This collaboration provided preservice teachers the unique opportunity to develop science units that could be implemented with young children at the local museum and in practicum placements in assigned classrooms. Each participating preservice teacher contributed one lesson that was organized and integrated into a comprehensive unit using adapted learning cycle pedagogy with three distinct phases—exploration, concept development, and application. These lesson plans use familiar items and materials that can easily be implemented by classroom teachers. A materials list, teacher background information, assessments, and outcomes are provided. This book selection includes the Table of Contents, Introduction, References, and Index.
