The image shows two young girls in a classroom. They are both wearing face masks and are sitting at a wooden table. The girl on the left is wearing a white sweatshirt and glasses, and is holding a small plastic bag with a white substance in it. She is pouring the substance into a yellow tray that is placed on the table in front of her. The other girl is sitting next to her, wearing a pink shirt and a face mask. Both girls are looking at the tray and appear to be engaged in a science experiment. In the background, there is a blackboard with Chinese characters written on it and a window with green curtains.
