6. Imagine that your lab partner is using the low power objective to examine a tiny organism swimming in a drop of water on a microscope slide. The tiny organism

dives straight down into the drop of water and disappears from view. Your lab partner is sad, because she's convinced that she will never see that tiny organism again. With your new knowledge of depth of field, explain what she can do to seethe tiny organism even though it has moved away from the layer of the water that is in focus.
