This lesson plan aims to provide students with an interactive experience with nature, focusing on maple trees' diversity and ecological importance in urban forests. Maple trees, belonging to the genus Acer in the family Sapindaceae, are significant in temperate regions of the Northern Hemisphere, especially in Autumn. Students engage with nature through an interactive scavenger hunt using identification cards and the iNaturalist app to document and analyze leaf characteristics. This lesson plan focuses on five common species found on the East Coast: Sugar Maple (Acer saccharum), Silver Maple (Acer saccharinum), Red Maple (Acer rubrum), Norway Maple (Acer platanoides), and Japanese Maple (Acer palmatum). The goal is to enhance students' understanding of tree diversity, leaf identification, evolutionary relationships, and ecological roles. This lesson plan results from the collaboration between Chestnut Hill College and Our Mother of Consolation School in Philadelphia, PA, funded by the Connelly Foundation.
