Eco-Missions: Learning Green Together

Students form small groups and choose one environmental mission to practice for a week (e.g., zero food waste, washing recycling bins, turning off lights, using tumblers). After practicing, they create visual records using Canva posters or CapCut vlogs to document their actions. Students then explore partner class works on Padlet, discover cultural differences in eco-practices, and prepare questions for a 40-minute live video call where groups introduce their actions and exchange ideas. Finally, the class votes to adopt one outstanding eco-friendly idea from their international partners as a new daily classroom rule.
