An appreciation of nature and an understanding of environmental issues help children become responsible world citizens. This curriculum provides upper elementary-aged children with the opportunity to explore environmental issues through the lens of phenology, which is the study of the recurring, seasonal rhythms in nature. In addition to engaging crafts and activities, students have the opportunity to be scientists as they participate in Indiana Phenology’s Schoolyard Phenology observation program by observing and documenting the spring awakening of plants on school grounds during the course of the 10-week curriculum. Each week there is a 1-2 hour lesson available.
