Using a Mass Balance Model to Understand Carbon Dioxide and its Connection to Global Warming
This activity has benefited from input from a review and suggestion process as a part of an activity development workshop.
This activity has benefited from input from faculty educators beyond the author through a review and suggestion process as a part of an activity development workshop. Workshop participants were asked to peruse activities submitted by others in their disciplinary group prior to the workshop. The groups then convened early in the workshop to discuss the materials and make suggestions for improvements. To learn more about this review process, see http://serc.carleton.edu/quantskills/review_processes.html#2004.
