Through activities and experiments, the children discover what role the atmosphere plays in the Earth's temperature and its liveability. They learn how nature has created a natural greenhouse effect, but also how humans are emitting more and more greenhouse gases into the atmosphere as a result of industrial activities, making the earth hotter and hotter. The children realise that our own livelihood depends on climate protection, the preservation of biodiversity and the availability of water and food. Based on their understanding of the phenomenon, the children develop their own projects as a team, which they implement together in order to effectively protect the climate.
