	Earlham College requests \$342,400 to develop multidisciplinary science curriculum modules and student/faculty research projects focusing on a common core problem: metals in the environment. This project will emphasize collaboration among our natural ~~and physical~~ science departments, including biology, chemistry, computer science, geosciences, mathematics, and environmental science. Scientific research is becoming increasingly multidisciplinary and collaborative; therefore, it is essential to train our students to develop multi-faceted approaches to problem solving. This project will introduce an important scientific problem, ask students to collect and analyze data, and to make interpretations using different disciplinary perspectives in both coursework and independent research projects with faculty. We believe this idea of collaborative multidisciplinary learning will transform our undergraduate curriculum in the sciences and provide a model for programs among the sciences at other liberal arts colleges.

We believe this idea of collaborative multidisciplinary learning will transform our undergraduate curriculum in the sciences and provide a model for programs among the sciences at other liberal arts colleges.

			A grant from the Keck Foundation would support a modest amount of equipment, curriculum module and seminar development, and student/faculty summer research, over three years. Curriculum modules will be created for both introductory and upper-division science courses. Field, laboratory, and computational methods will be integrated in the modules for students at all levels to experience first-hand how modern scientific inquiry is carried out using a multidisciplinary approach. Our study of metals in the environment will generate module and research topics reflecting faculty expertise, student interest, and local impact. Following the scientific and pedagogical success of this initial topic, we intend to expand it to reflect the changing interests of students, faculty, and the community. We will study anthropogenic impacts on two local ecosystems: nearby Springwood Lake with documented pollution impacts from industrial activity and a site on campus.

Earlham College is a four-year, private, coeducational institution providing a liberal arts education for 1200 undergraduates.Â In 2000, Earlham ranked eighth among 1302 institutions of higher learning in the Biological Sciences category of the Baccalaureate Origins Report.Â One quarter of Earlham students major in science.Â Earlham's teaching philosophy strongly emphasizes collaborative student/faculty research, both within courses and extracurricularly.Â Earlham students regularly present papers at the annual Butler University Undergraduate Research Conference and at the annual Merck/Earlham College Undergraduate ResearchÂ Conference, and at national conferences in a wide range of science disciplines. Students are frequently co-authors on papers submitted to refereed scientific journals.

	Four aspects of our project work together to make it powerful: 1) our focus on local problems; 2) the combined use of field, laboratory, and computational methods; 3) the longitudinal involvement of students as they take introductory through upper-level science classes; and 4) showing students how modern science is multidisciplinary with teams of scientists who inform and illuminate the different disciplinary perspectives of a problem.

	An important artifact of this project will be further development of Earlham's Environmental Studies program, which is largely staffed by the same faculty that would be a part of this work.

	Because this project will impact the local community, we will hold an annual poster session for the public in which faculty and students will present their results. We believe this innovative approach of combining classroom scientific inquiry, summer research projects, multidisciplinary discussion, and community participation will give our students a unique opportunity to engage in truly modern collaborative science.

	The costs involved in the proposed ~~interdisciplinary~~ project exceed the capacity of Earlham's operating budget. In order to plan and implement this project, we must secure outside funding. Private and government funding for multidisciplinary projects at 4-year colleges is limited. Furthermore, many focus on one core discipline with collaborative disciplines radiating from the core.

	With educational programs that have strength across the full range of the liberal arts and sciences, Earlham has demonstrated unusual strength in the sciences, and is well-positioned to develop and disseminate the multidisciplinary approach to science education described in this proposal.

	'''Upper Division Course Modules:''' Hydrogeology serves to illustrate application to an upper-level course. The lab modules for hydrogeology will target complete hydrogeologic characterization of both the on-campus research plot and Springwood Lake. For the on campus plot, this will entail installation of ground water monitoring wells and multi-level piezometers. Subsurface hydraulic properties will be ~~calculated on the basis of~~ constant head slug tests and constant discharge ~~pumping stress~~ tests ~~and monitoring points will be chemically characterized to establish background conditions prior to experimental metal dosing~~. ~~Total metal concentrations will be quantified by~~ Inductively-Coupled Plasma ~~spectrometry (ICP~~) ~~and aqueous~~ species distributions will be ~~modeled~~ using a public-domain equilibrium speciation model (e.g. MINTEQA2,PHREEQC). Hydrogeology students will ~~be engaged in~~ all facets of the subsurface investigation, aquifer property determination and sample collection. Students in other courses will cooperatively engage with Hydrogeology students to develop the protocols for running the environmental fate experiments, chemical analyses and equilibrium speciation modeling.

For the on campus plot, this will entail installation of ground water monitoring wells and multi-level piezometers. Subsurface hydraulic properties will be determined via constant-head slug tests and constant-discharge pump tests. Quantitative analyses (using Earlham's Inductively Coupled Plasma spectrometer) will establish baseline metals concentrations. Students will track the environmental fate of target metals added to the control plot under controlled conditions. Aqueous species distributions will be calculated from concentration data using a public-domain equilibrium speciation model (e.g. MINTEQA2,PHREEQC).

			The proposed modules for Hydrogeology will give students an experience that embodies much of the professional practive of the science. Students will conduct all facets of the subsurface investigation, aquifer property determination and sample collection. Students in other courses will cooperatively engage with Hydrogeology students to develop the protocols for running the environmental fate experiments, chemical analyses and equilibrium speciation modeling.

This unit will introduce students to fate and transport modeling of metals by measuring the distribution coefficient, Kd, which is a common parameter used to estimate the concentration of metal pollutants in aqueous systems. Kd is a measure of the chelating ability of the soil in a soil-water mixture. A distribution coefficient for copper has previously been measured in a standardized soil ~~material1~~, and the procedure will be adapted to soils collected from our study sites. The module will be conducted over two laboratory periods.

	'''Biology:''' Initial work in the biology department will include the sampling of aquatic biota (macropthytes and animals) in Springwood Lake in order to describe and quantify the food chains, evaluate the extent of bioaccumulation of metals by those organisms, and assess the rates of biomagnification occuring in higher trophic levels.

	'''Geosciences:'''		'''Geosciences:''' Summer research in the geosciences department will focus on characterizing the physical properties of subsurface soils by conducting whole-soil hydraulic conductivity tests and laboratory grain-size analyses. Additional work will focus on determining soil reactivities of soil minerals by quantifying mineral constituents, cation-exchange capacities, organic matter content and
