Over the course of two years, fifth grade students at The Chapin School, a New York City-based independent school, engaged in a project-based learning unit connected to the Science curriculum, to gain an understanding about the air quality in their community. As they measured and analyzed air quality parameters, students were inspired to take action to improve air quality both at school and across the boroughs of New York City. When the second year was interrupted by the global COVID-19 pandemic, teacher Anna Jacinta Mello rose to the challenge and adjusted activities so that students could continue their research virtually.
