We are using Nature's Notebook to engage 150 introductory biology students/year in tracking fall and spring phenophase changes for eight tree species on Salisbury University's campus. This Course-based Undergraduate Research Experience is designed to achieve three goals: 1) the social goal is to foster a sense of place, sense of belonging, and sense of community; 2) the skill goal to promote a sense of agency with science skills; and 3) the research goal is to use campus tree phenology as a local measure of climate change.
