ESS2.C: The Roles of Water in Earth’s Surface Processes
As a class, students discussed how a lake forms, including some of the processes involved in the water cycle. After the discussion, students were asked to draw a representation of how a lake forms.
Students attended to some aspects of the water cycle as a causal mechanism for lake formation. In particular, Sample A shows how rain and precipitation produce water from the sky that forms the lake. However, the processes of evaporation and condensation were not as explicitly prevalent in this sample, although proto-thinking may be occurring with the labeling of the sun and the clouds, with apparent differences between the clouds in the first two panels and the “no rain cloud” in the far right panel.
