Little Flower students spent 5 days travelling around Philadelphia with Scott Quitel from the Land Health Institute. They learned about the urban environment through experiencing the myriad layers of which it is composed.  Experiential activities included: bird watching, plant identification walks, geology tours of natural and built environments, visits to water infrastructure sites (e.g. sewage treatment plants), and learning to distinguish soil types by feel.  In addition to studying natural systems, Little Flower students learned about underlying human-derived “layers” that impact natural systems:  arts and culture groups using greenspace, pollution and climate change within Philadelphia and how it relates to these green spaces, systemic root causes of litter that may be cultural or institutional.
