Assess students' understanding of how transportation choices (cars, buses, trains, walking, biking, scooters) affect local air pollution and community health. Focus on cause-effect links between vehicle emissions (PM2.5, NOx, CO2), exposure pathways, common health outcomes (asthma, respiratory irritation), and local design factors (traffic volume, idling, bike lanes, transit access). Include interpretation of simple data or scenarios and identification of practical mitigation strategies (public transit, active transport, electrification, traffic calming).
