The image shows three young girls sitting at a green table in front of a blackboard in a classroom. They are all wearing white t-shirts and have lanyards around their necks. The girl on the left is wearing glasses and is smiling at the camera. The other two girls are wearing green shirts and are also smiling. On the table, there are three small structures made of paper and plastic bottles. The structures appear to be made of different materials and are arranged in a triangular formation. The blackboard behind them has Chinese characters written on it.
