Today, we invited Teacher Tsai from Re-Think to our school, who introduced us to a very interesting board game called "City of Renewal". This is a board game with a theme of environmental protection and resource reuse, and it's indeed a large-scale educational tool! Through its rich gameplay, students can understand which products belong to which substances from the cards they draw, whether these substances can be recycled or will cause environmental pollution. In the game, everyone works together to establish recycling centers, reduce carbon emissions, and recycle resources while learning and having fun, and at the same time, they build up their knowledge and concepts of environmental protection in the world.
