In early childhood education programs, exploring the surrounding environment in kindergarten classes for 5-6-year-olds plays a crucial role in providing fundamental knowledge to children before they enter primary school. Guiding children to explore the environment involves teachers creating an environment, setting up situations, and organizing activities for children to interact with and experience the objects and phenomena in their surroundings.
