This picture depicts the scene of a Biology laboratory. There are four students crowding aroung a table and performing an experiment. They are handling agar plates. One of them is holding an agar plate and striking it with a metal object. I think the girl is doing the striking, to seperate huge colonies of microorganisms into single colonies fof future experiments. Clad in white laboratory clothes and elastic gloves, the students seemed engrossed in their experiment. I think the white laboratory clothes are to prevent their clothes from getting dirty. The guy on the left hand side is leaning his weight on the table. Staring hard at what the girl with the agar plate is doing, I think he is watching the girl, awaiting to correct her mistakes. Perhaps they have a group assesment task, requiring every group member to asses the performance of one another. This group of students are more likely to be in polytechnics or junior colleges as we do not wear white laboratory clothes when performing an experiment when I was in primary and secondary school. In conclusion, I think the students are enjoying the experiment with the smiles on their faces. Perhaps these students will have to wait for several days before they can clearly observe the appearance of single colonies of microorganisms and conduct experiments on them.
