The image shows a classroom with a desk and a bulletin board in the background. On the desk, there is a small wooden structure made up of three tiers. The structure appears to be made of light-colored wood and has a rectangular base with a flat top. The top tier has a small window on the left side and a small door on the right side. The bottom tier has two smaller windows on the top and a smaller window in the middle. There is also a wooden box on the desk next to the structure. The desk is covered with a green tablecloth and there are bookshelves and other school supplies scattered around the room.
