In a brightly lit school science lab, a student in a white sweater is conducting an experiment. She stands at a red countertop with a white sink, carefully manipulating a dropper that is attached to a long glass cylinder held in place by a metal stand. Below the dropper are two beakers filled with liquid. There is a metal ring stand and a gas line on the counter next to the sink. Papers with writing on them are scattered near the sink. Another student is at a desk near the windows in the background.
