Did light penetrate better in the sunny areas or the shaded areas? Explain your
answer.
What will be an ideal response?
All things considered, light should penetrate farther in the sunny areas unless there
is a floating algal mat or other floating aquatic vegetation in the sunny locations. In
the shaded areas, the amount and intensity of the light striking the surface of the
pond or lake are greatly reduced. The water may have greater clarity because algae
will tend to congregate in areas with enough light to support photosynthesis. If the
area that you selected for your students to sample is close to the place where a
stream, creek, or river enters the pond or lake, the results you obtain may be highly
variable. Streams with a high velocity may be carrying a high sediment load, which
will reduce the depth to which light penetrates in the area where the water enters
the lake.
