The video shows a classroom with a teacher standing in front of a whiteboard and a projector screen. The teacher is wearing a green shirt and glasses and is talking to the class.

The walls of the classroom are decorated with posters and signs, and there is a bulletin board with papers and notes on it. The lighting in the room is bright, and the overall atmosphere appears to be calm and focused.
