Inland water chemistry: the Nordic Lake Survey 1995
Tom Andersen, University of Oslo, Norway
While the ionic composition of surface seawater is basically the same anywhere in the world's oceans, the chemistry of inland waters can vary by orders of magnitude over short distances. In this activity we ...

Atmospheric Carbon: Can We Offset the Increase?
Joceline Boucher, Maine Maritime Academy
This activity lets students discover first hand how the big issues in climate change -- here, the increase in atmospheric CO2 and the utility of carbon offsets -- can be understood through measurement, application ...

Teaching the nitrogen cycle and human health interactions
Margaret Townsend, University of Kansas Main Campus
This activity uses objects, pictures, and text in a matching game to define the nitrogen cycle and the environmental and human health impacts of nitrogen. The game can be used to associate useful and detrimental ...

independent soil investigation project
Stephanie Ewing, Montana State University-Bozeman
Students demonstrate their skill in soils investigation and interpretation through independent projects undertaken in groups of one to three and presented in class using visual aids.

Soil Biogeochemical Cycles
Colin Robins, Claremont McKenna College
This group activity charges students with teaching their colleagues about the biogeochemical cycle of one key soil element (e.g., either C, N, S, P, Ca, or Fe). Students are given a single class period to summarize ...

Systems Geobiology Powers of 10
Bruce Fouke, University of Illinois at Urbana-Champaign
Systems Geobiology is the study of complex interactions arising from the interplay of biological, geological, physical, chemical and even social systems across multiple spatial (microns to thousands of kilometers) ...

Review for interdisiplinary science course (stream ecology, watersheds)
Cailin Huyck Orr, Carleton College
This is a large-scale participatory activity used to prompt students to review what they have learned and to think actively and cooperatively about the connections between the systems we have discussed prior to the ...

Wheel of... Geology!
Rebecca Teed, Wright State University-Main Campus
This quiz game is intended to help students review for an upcoming exam. Topics of questions are randomly determined by spinning a wheel. Teams answer questions using electronic CPS handhelds. -

Carbon in the Oceans
Amy Townsend-Small, University of Cincinnati-Main Campus
In this assignment, students in small groups are asked to interpret and explain a figure depicting one aspect of marine carbon biogeochemistry. Then a representative of each group explains the figure to the class.

How to read elemental soil profiles to investigate the biogeochemical processes in Critical Zone?
Lixin Jin, University of Texas at El Paso
In this exercise, students use elemental chemistry data in a soil profile to explore major biogeochemical processes that dominate in critical zone. Data will be provided, and students calculate and graph the mass ...
