Tracers in the hydrologic cycle: A jigsaw activity part of Cutting Edge:Complex Systems:Teaching Activities
Using a jigsaw approach, students investigate biogeochemical transformations (nitrate, silica, pH and conductivity) of water as it moves through the hydrologic cycle. The resulting conceptual framework facilitates later use of tracers in evaluating runoff mechanisms and sources of stream flow.

Bedform mapping in a coastal environment part of Cutting Edge:Sedimentary Geology:Activities
Students use a learning cycle of prediction-observation- comparison to investigate diverse bedforms exposed at low tide at a beach/inlet/tidal-delta complex and to relate them to formative flows.
