Two months prior to the program’s start, we will send students kits to measure air quality in their hometowns and college campuses. These kits, called HazeL, were designed by the Harvard SEAS Active Learning Labs for project-based classroom learning during the academic year, and can measure particle concentrations in the air. After tracking air quality at home, the students will bring the HazeL monitors back to Harvard, where they will test air quality in different Boston-area neighborhoods. Students will then work together to map out air quality across the United States and in Boston, and will learn to interpret the spatial and temporal patterns that emerge. Through this collaborative project, students will learn about collecting, analyzing, discussing, and presenting data.
