The woman came to the lab to do an experiment. There is an older woman standing in the background overseeing the experiment to make sure everything runs smoothly and no mishaps occur with mixing the chemicals. The woman in the front is calm, but potentially nervous, to have someone watching over her doing her experiment. The older woman is nonchalant, with her hands in her pockets. I assume that both women are familiar with one another and are comfortable working together. There faces show no signs of concern or anxiety. After the woman finishes mixing the chemicals together, they will move on to another step of the experiment. The woman in focused on doing this experiment correctly and that is what she is thinking about. The older woman is also just focused on what the woman is doing and whether or not she is doing it correctly as it is her job to overlook the experiment.
