Building chain of reasoning fromcause to effect. Building chain of reasoning from observation to interpretation. Each student-pair works with data from one site. Black Rock Forest OpenLowland works especially well for this investigation. For this data set, thestudent-pair prepares a scatter plot of temperature versus water vapor.
Students examine anddescribe the resulting graph.
There is a wide range oftemperatures in the data. But there are no data points with lowtemperature and high water vapor. This combination of conditions neverhappens. For each point thatthey plot by hand, students should state whether or not condensation wouldoccur. Dewpoint Students are given a beaker, ice cubes, a thermometer, water.
