The image shows two young children, a boy and a girl, sitting at a table in a classroom. The boy is wearing a blue sweater and is pointing at a small glass jar with a blue lid. The jar is filled with sand and there is a small amount of sand inside. The girl is also wearing a pink sweater and has her hand on the jar. They are both looking at the jar and appear to be engaged in a science experiment. In the background, there are other children sitting at their desks and a blackboard on the wall.
