Using teachers as co-researchers to collect and analyze data, this case study explored preschool and kindergarteners' learning when they were engaged in hands-on activities in the garden and greenhouse areas of a model outdoor classroom. Key findings suggest that when young children are participating in garden and greenhouse activities they are: (1) communicating their knowledge about the world to others, (2) conveying (and learning to process and manage) emotions, and (3) developing important skills (e.g., initiative, self-confidence, literacy, math, science skills) that will help them be more successful in school and better navigate the world.
