In connection with World Environment Day, students will make environmentally friendly decisions in their daily lives, make their days more sustainable, and try to save our nature. In the project, we use various activities and different tools - a Kahoot quiz about the environment, a photo scavenger hunt for green activities, a homework photo book with eco-friendly activities in daily life, and Padlet for brainstorming, sharing results, and reflection. We use AvatarMaker and Padlet for student medallions and international collaboration and communication. In TwinSpace, we share results and communicate via chat and video.
