Winston Wonders Why the Rain Falls is an original, research-informed children’s picture book designed as an instructional tool that integrates early STEM learning with character education. Set in Olympic National Park, the story follows Winston, a curious beagle, as he explores the science of rainfall through interactions with animals who each offer a different explanation grounded in their lived experiences. Through these encounters, young readers are introduced to foundational earth science concepts while also learning how knowledge is shaped by viewpoint, environment, and lived experience. The book is intentionally designed to support early childhood and elementary learning contexts, including classrooms, homeschooling environments, and family-based literacy experiences. In addition to reinforcing science content, the narrative emphasizes dispositions such as curiosity, empathy, and openness to multiple viewpoints, which are core components of character development and inquiry-based learning. As part of a broader educational series, Winston Wonders Why integrates literacy, STEM learning, and place-based education, and is accompanied by an optional activity guide that extends learning into geography, science, and applied exploration.
