Due to popular demand, the Butzows have put together more fascinating thematic units that make science more exciting for young learners. Each chapter focuses on an individual book and includes vocabulary; concepts; applications; and a wide variety of activities, including hands-on and inquiry-based topics, games, puzzles, word searches, and more. The authors' approach helps connect the conceptual content to real-life experiences. Physical, life, earth, space, and environmental sciences are included.
