Nitrogen biogeochemistry of headwater catchments underlain by discontinuous permafrost
In this TIEE data set, students answer the question of what influences flux of nitrogen from catchments underlain by discontinuous permafrost.
Students work with a large dataset describing nitrogen dynamics in the Caribou-Poker Creeks Research Watersheds, small watersheds in the boreal forest that are underlain with various extents of permafrost cover. Students use spreadsheet and graphics software to investigate responses of N cycling to permafrost, seasonal patterns, and inter-annual variation by 1) making observations concerning long (inter-annual) and short-term (seasonal) patterns in nutrient concentrations in streams, 2) hypothesizing about physical and biological conditions influencing nitrogen chemistry, and 3) testing predictions using graphical analyses.

| Pedagogical Use Description | Skills used include drawing observations from graphical data, hypothesizing, calculations and preparation of figures from large datasets, graphical analyses, facilitated group learning, and written presentation of results. Student-active approaches include investigating causal relationships, calculations, preparation of graphs, and interpretation of data. Communication activities include think-pair-share, class discussion, and presentation of findings with the class or in written reports. Assessable outcomes include formative assessment via small-group and class discussion; display-quality figures; written and verbal presentation of observations, analyses, and interpretation. |
