Earlham College requests $358,877 to develop multidisciplinary science curriculum modules emphasizing computational methods and student/faculty research projects focusing on a common core problem: metals in the environment. This project will emphasize collaboration among our natural science departments, including biology, chemistry, computer science, geosciences, mathematics, and environmental science. Scientific research is becoming increasingly multidisciplinary, collaborative, and computational. Therefore, it is essential to train our students to develop multi-faceted approaches to problem solving that use both traditional laboratory techniques and computational methods. This project will introduce an important scientific problem (metals in the environment), ask students to collect and analyze data, and to make interpretations using different disciplinary perspectives. 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.

1)Statement of the work to be undertaken and expected significance.

One important objective of scientific research applied to the environment is to determine the extent, the magnitude and the timing of adverse human impacts upon natural systems. In the past decades, major research efforts have addressed such problems and have led to both enhanced media attention as well as a groundswell of students who are interested in solving environmental problems. Science courses at the undergraduate level can capture student interest by explicity focusing on environmental problems.

One of the traditional difficulties in science education is teaching scientific content in a way that builds a strong understanding of the mechanisms of scientific inquiry. A large proportion of existing survey courses, often targeted at fulfilling institutional science requirements, introduce a large amount of content and require low levels of critical thought. Upper level courses more commonly focus on higher orders of problem-solving but are almost always discipline-specific and lack clear multidisciplinary links.

In this proposal, we reformulate the model of undergraduate science. In lower-division classes, we emphasize the mechanisms by which scientific knowledge is acquired in an environmental context, thus reinforcing student interest in environmental problems and teaching them the methods of authentic scientific inquiry. In upper-division courses, we will focus on the multidisciplinary aspect of modern science, by exposing students to the many different disciplinary lenses through which to view scientific problems.

2)Objectives/goals for the proposed work.

Major goals for this proposed work include:

• Bridging the gap for students between scientific research and science education by incorporating research modules into several lower and upper division courses
• Increasing student and faculty understanding of multidisciplinary use of field, laboratory, and computational methods to solve a particular problem
• Conducting an extensive study of the fate, transport and toxicity of metals in our local watershed
• Encouraging student interest in the sciences
• Expanding Earlham’s Environmental Sciences program by incorporating the study of environmental issues into the core courses of several disciplines
• Developing a workshop to teach faculty at other liberal arts colleges how to incorporate multidisciplinary research modules into their science courses

3)Project timeline keyed to the objectives/goals.

The implementation of this project begins with the development of the instrumentation and computer interfacing necessary to monitor field sites as well as the development of the first sets of curriculum modules to be integrated into both lower and upper division science courses. It continues with the development and implementation of the remainder of the proposed curricular modules and ends with plans to conduct a faculty development workshop to disseminate the process and content of developing integrated multidisciplinary research modules with a computational modeling component as well as the evaluation of the project.

4)Relation of the objectives to:

• the present state of knowledge in the field

Inquiry-based, multidisciplinary science education that involves computational technology is transforming the landscape of undergraduate learning in the natural sciences. Courses that are shaped around the practice and process of science rather than the rote mastery of facts and theories have been known to significantly enhance the learning of science in undergraduate courses (NRC, 1996; McConnaughay et al., 1999; Uno, 1999). In addition, the importance of computational science in answering disciplinary research questions requires rethinking standard science curricula at the undergraduate level. Currently, several national mandates call for this type of curriculum restructuring (NRC, 2003; PITAC, 2005).

Lake bottom sediments are often found to be excellent repositories of information about the timing and magnitude of anthropogenic impacts to watersheds. As well-stated by Smol (2002), sediments are "an ecosystems memory" in that they collect and integrate pollutant signals introduced to lakes from both local and regional sources. Bottom sediments have been used as archives of pollutant history in numerous studies of lakes, rivers, deltas, bays and estuaries (Latimer, 2003) and open marine shelves. Among the most significant results from sediment pollutant archive studies is the ability to segregate natural (geogenic) elemental flux and storage from that directly related to human impact (anthropogenic). While, in many cases, a strict segregation of geogenic from anthropogenic influences is not possible, in many other cases this determination may be reliably assigned (Reimann, 2005; Reimann, 2004; Reimann, 1998; Matschullat, 2000). Sediment archive studies commonly reveal a upward trend of pre-disturbance background concentrations that increase in proportion with human perturbation. Sometimes, concentrations then decrease upward reflecting the efficacy of applied environmental controls.

Springwood Lake (SWL) is an ideal mesoscale laboratory for investigating the fate of metals in a lacustrine setting. We selected Springwood Lake in Richmond, Indiana for several reasons.

First, Springwood Lake is a small lake (~ 8 acres) that is at the lowermost end of a small tributary drainage. In addition to being small in area, the lake is relatively shallow. The lake partially freezes over during some portions of the winter which eases core collection.

Second, Springwood Lake is located in our backyard, making site visits and sample collection easy to coordinate. This proved to be especially important in coordinating sediment core recovery as our sampling was conducted through the frozen surface of Springwood Lake. As Springwood Lake receives a significant portion of inflow from springflow discharge - with an average temperature of 53 F ( C) - the time intervals permitting through-ice sampling were short-lived and required frequent observation.

Third, the watershed area that drains into Springwood Lake is characterized by land-uses that are historically associated with environmental contamination. These land-uses include large-scale industrial and manufacturing facilities and unregulated and regulated solid waste landfills. The industrial and manufacturing facilities that are (or were formerly) located within the Springwood Lake watershed produced: munitions; automobiles; jet engines; refrigerators; steel; wire and cable; and..... The land-uses formerly or presently within the watershed are listed in Table 3 and are located on a watershed map in Figure 2.

Fourth, Springwood Lake has been in existence for a finite, known time period, having been developed in 1930 as the result of impounding a natural spring-fed wetland. As a consequence, Springwood Lake sediments have accumulated only during the last 75 years. Thus, the sediments are comparatively thin (usually < 1 m in thickness) and they transition abruptly to the former land surface soils. The flooding surface (light-colored clayey sands) is readily discriminated from the lacustrine sediments (black, organic matter-rich gyttja) which permits temporal control on sediment accumulation and determination of sedimentation rates for different areas of Springwood Lake. Dating average sedimentation rates allows us to assign a crude time framework to core intervals.

This is significant because this time frame brackets the rapid expansion of industrial and manufacturing operations in the United States in general and in Richmond in particular. Much of the industrial development that is located in close proximity to Springwood Lake was developed after initiation of the impoundment. Additionally, this time interval has seen not only the expansion of source activities, but also their dramatic reduction as a consequence of environmental controls on pollutant releases. This is particularly important with respect to the ban on tetraethyl lead in gasoline.

Fifth, the industrial and manufacturing facilities within the Springwood Lake watershed have been documented as sources of uncontrolled pollutant releases to the lake. The industrial activities within the Springwood Lake watershed have resulted in large scale contamination of subsurface soils and ground water. Large contaminant plumes of chlorinated organic solvents reside beneath some of the industrial facilities in close proximity to Springwood Lake. Recent (March 2005) sampling and chemical analyses of springflow discharge entering Springwood Lake has verified that chlorinated solvent introduction continues to the present.

Lastly, Springwood Lake is important as a recreational destination for the Richmond and Wayne County community. When first created, Springwood Lake was used extensively as a location for recreational swimming and water skiing. More recently, the accumulation of sediment has restricted use of motorcraft. Springwood Lake is the visible entry to Richmond=s largest city park, encompassing _____acres. The park is populated by educational hiking trails. The western border of the park, immediately uphill from Springwood Lake, is the location of the Cardinal Greenway, a reconstituted Arails-to-trails@ bike path that is used extensively for recreation by the local population. Springwood Lake Park enjoys constant visitation during the year and is used extensively as a source of fish.

• work in progress by the project personnel under other support

There has been a long tradition of Earlham science faculty involvement in multidisciplinary and computational student/faculty research. In the last 20 years, faculty members in biology, geology and chemistry have been engaged in studies ranging from atmospheric measurements of mercury and aquatic ecosystem studies at the college's Dewar Lake Biological Research Station to determination of metal contamination in lake sediments. Across our science curriculum, a strong emphasis is placed on quantitative, analytical and research-based projects. Many of our research projects engage our student/faculty teams in multidisciplinary efforts; currently, our computer science faculty and students work with both biologists and chemists on computational projects. e.g. computational phylogenetic reconstruction and molecular dynamics simulations. For many years, our biology and chemistry departments have collaborated on a variety of research and curriculum projects, e.g. determination of atrazine concentration from agricultural runoff in local water sources and its effect on the physiological development of aquatic species.

Additionally, many of our science faculty have worked with state, municipal and public representatives to provide expert witness on local environmental issues. Examples of collaborative input to local issues include:

• work in progress at other institutions

Many institutions have recognized the need for innovative approaches to science education at the undergraduate level. Carleton College has established an Interdisciplinary Science and Math Initiative (CISMI) aimed at integrating the physical sciences and mathematics in undergraduate courses and research projects. Additionally, Carleton College is currently working on ways to integrate computational modeling across their curriculum to enhance learning. Carleton is also emphasizing computational science at all levels of the curriculum, which is similar in scope to our proposed project. Trinity University is also focused on interdisciplinary faculty and student research as well as interdisciplinary curricular development with their recently funded Keck Center for Macromolecular Studies; however, Trinity’s program has a major focus on the integration of biology and chemistry, while our proposed program uses biology, chemistry, geosciences, mathematical, and computational science methods to explore environmental problems. Shippensburg University of Pennsylvania has implemented an Interdisciplinary Watershed Research Laboratory for field-based environmental laboratories. This project is similar in scope to our proposed project, but primarily integrates biology and geography/earth science, while we are proposing to involve more disciplinary perspectives.

It is well-known that trace elements and heavy metals occur in natural water systems in a variety of forms including individual hydrated ions, ion pairs, complexes with inorganic or organic ligands, colloidal complexes and as adsorbates to varying size fractions of particulate matter (Drever, 1988; Tanizaki, 1992; Hem, 1989). Elemental form and bioavailability are controlled by speciation which is governed by the master variables pH and Eh and other characteristics of the aqueous solution chemistry such as ionic strength (Stumm and Morgan, 1996).

also similar in that they all exhibit multiple valences, and hence, are sensitive to oxidation - reduction reactions (Reimann and Caritat, 1998).

Processes effecting mobilization may be summarized as: dissolution in oxidizing freshwater, complexation with aqueous ions, sorption to hydrous metal oxides and transport away from the site of release by advective flow of dissolved, colloidal and suspended particulates. Mobilization processes are ubiquitous in near surface environments due to chemical weathering, are geographically widespread and are expected to generate dispersed spatial gradients of concentration change (Fortescue, 1992). Processes of sequestration may be summarized as: removal via precipitation or co-precipitation in reduced or evaporated freshwater, complexation with humic substances, sulfhydryl surface functional groups in thiols and release from solid surfaces by reductive dissolution of hydrous metal oxides followed by insolubilization by further reaction. Sequestration processes occur at geochemical barriers, which are geographically localized and highly specific geochemical microenvironments (Perel'man, 1977). Geochemical barriers are characterized by steep concentration gradients over short spatial scales.

The physical and chemical characteristics of a watershed are strong first-order controls on the environmental fate of heavy metals and trace elements (Elder, 1988). Particle-mediated transport is well-documented to control the environmental fate of many contaminants. Most (90 to 99%) of the pollutant load of heavy metals and trace elements are associated with sediments (Helsel and Koltun, 1986; Horowitz, 1985).

Particle-associated contaminants have been observed to be controlled by the erosional and depositional characteristics of watersheds (Graf, 1996; Miller, 1997). This is a departure from the classical assumption of exponential concentration decrease with flow distance (Hawkes, 1962; Thomann and Mueller, 1987). Instead, contaminant concentrations may be controlled by the location and efficiency of particle trapping mechanisms independent of distance along a flow gradient (Graf et al., 1996 et al., 1996; Graf, 1996). This phenomenon has been observed for Mo (Kaback, 1977). Within most watersheds, sediment trapping efficiency is greatest at lakes and impoundments (Curr, 1995).

Lakes and ponds are efficient sinks for trapping, storing and recycling trace elements within watersheds (Lahann, 1977; Viollier et al., 1997).

5)Concise description of methods and procedures for implementation and experimentation.

• Overview goes here

Curriculum modules will be incorporated into 6 introductory courses and at least 7 upper level courses in biology, chemistry, computer science, geosciences and mathematics. During the academic year, students taking courses that include these modules will be strongly encouraged to participate in a weekly, faculty facilitated seminar in which they will discuss their course experiences. At the end of each semester, students participating in courses that have these modules will be required to attend and present their group projects at a locally hosted poster session. Initially, the summer research component will involve developing and testing curriculum modules. In summers two and three, students will have the opportunity to conduct more advanced research related to metals in the environment including analyses of metals in a variety of environmental matrices, descriptions and quantifications of food chains and computational modeling of rates of biomagnification of metals at higher trophic levels, performance of whole-soil hydraulic conductivity tests and determination of soil mineral reactivities, and computer modeling of biochemical and groundwater processes. All students participating in summer research will have two opportunities each week to discuss the multidisciplinary perspectives related to their projects: faculty from all departments will facilitate a weekly seminar and students will discuss their research projects in a student-led seminar.

• Either by department or as a whole describe the summer research activities. Some of this is course module development and some "real" research. Developing local soil models, database (post grant).

• Each courses' plan goes below. We need to show linkages between each of these courses where possible, both intra and inter departmental.

chemistry

Throughout our projects, site-specific data will be collected and models will be used to assess the fate and transport of metal contaminants.

We propose to incorporate a new environmental chemistry module in our general chemistry class (CHEM 111, typical enrollment of 90). This unit will introduce students to fate and transport modeling by measuring the distribution coefficient, Kd, which is a common parameter used to estimate the concentration and movement of metal pollutants in ground water. Kd is a measure of the extent of interactions between a pollutant and the soil matrix and is one of the keys to the understanding of the mobility and persistance of metals in the environment. A distribution coefficient for copper has previously been measured in a standardized soil material (Dunnivant, 2002), and the procedure can be adapted to soils collected from our study sites.

The module will be conducted over two laboratory periods. The first week will consist of a spectroscopy lab, where the students will be introduced to atomic and molecular absorption for the determination of the metal concentration in water, and to infrared spectroscopy for the characterization of the soil. In the second week, students will use atomic spectroscopy to determine Kd of a metal (copper in year 1, and additional metals in subsequent years) in both standard soils, and soils collected from both our field and test sites.

The distribution coefficient for metal contaminants varies greatly with experimental conditions, both of the soil and the aqueous system (pH, ionic strength, concentrations of pollutants, etc.). This variability will be illustrated by looking at the effect of pH on Kd for the soils investigated. The results will be used to discuss such environmental issues as acid rain and metal mobilization. Using the Kd results obtained in the laboratory and some simple assumptions, students will calculate a retardation factor(R) for the movement of the metal through the soil/water system (R = (1 + (pb/ne) * Kd)), where pb is the bulk density of the soil and ne is the soil porosity at saturation) . The effects of the chemical changes on Kd and on retardation factor will be modeled using a spreadsheet based model. The soil Kd results will also be integrated in a database for use in transport modeling, and could be further studied in the student research projects in the Equilibrium and Analysis class (CHEM 331).

The Equilibrium and Analysis course (CHEM 331) is a sophomore level course with an approximate enrollment of 25 students per year. The module for this course will be conducted during a two-week laboratory (four lab meetings) and will use diffusive gradients in thin films (DGT) to determine the speciation of metals (Cu, Ni and Zn) in both simulated laboratory solutions as well as water samples obtained both from the field site and the off-campus site. The speciation results of the DGT study will be compared to the results obtained with the speciation model Visual MINTEQ, a freeware version of the program released by the United States Environmental Protection Agency (USEPA).

This experiment will replace two of our current labs designed to expose students to atomic spectroscopy. It will accomplish the same pedagogical goal of teaching students how to prepare samples and standards for atomic analysis, as well as provide them with hands-on experience with the equipment necessary for spectroscopic analyses. Moreover, students will now also learn about ion exchange, metal speciation, the environmental importance of bioavailability, as well as the power of computational modeling.

In DGT, metals are accumulated on an ion exchange resin imbedded in a hydrogel and covered with a diffusion layer of a different hydrogel and a filter (Zhang and Davison, 1995). In this technique, the transport of metal ions to the resin occurs only by molecular diffusion (ref), resulting in a direct linear relationship between the metal mass accumulated and the time of deployment (see figs 1 and 2 – from Zhang and Davison, 1995))

The advantages of DGT include its simplicity, relative independence from hydrodynamics of the system, multi-elemental capability and its inherent pre-concentration capabilities, which enables the measurement of even extremely small concentrations in solution. With this technique, only the labile forms of the metals in solution (i.e. the inorganic free metal forms and organic labile complexes) will be measured. In addition, since the labile inorganic and the labile organic complexes have different diffusion coefficients in the hydrogels, the concentration of each type of species can be determined by this method. Zhang and Davison (2000, 2001) have shown that by varying the properties of the diffusion hydrogel, both the organic and inorganic metal concentrations can be obtained. In addition, the authors demonstrated that a single DGT device, with a very restrictive pore size, could measure the labile inorganic concentration with only a small correction factor. When using a single DGT device, the total concentration of a metal in the solution must be determined, and the difference between that total value and the DGT value will represent the organically bound metal. Because of their well characterized nature, we will purchase the DGT device components from DGT Research Ltd during the first few years of implementation. As part of the summer research, we intend to characterize the diffusion coefficients of various metals and organic species (humic and fulvic acids) in polymers that we will synthesize. In addition, resins other than the standard Chelex (used to bind many +2 and +3 ions) can be explored for selectivity of other metals or oxidation states that are bound tightly to Chelex.

In practice, these devices are deployed into a well-stirred solution for times ranging from hours to days. After this time, the device is disassembled and the metals are then eluted from the resin using a nitric acid solution and analyzed using either graphite furnace atomic absorption spectroscopy (GFAAS) or inductively coupled plasma atomic emission spectroscopy (ICP-AES).

Three different systems will be tested using this method: a laboratory system with known parameters, a water sample from our field site, and a water sample from our remote site (Springwood Lake). These water samples can be tested both for endogenous metals as well as spiked laboratory samples. The water samples from the field site and remote site will be characterized by the teaching assistants for the additional parameters required for Visual MINTEQ modeling, but not measured directly by the students in the course (such as anions).

Previous literature indicates that DGT can accurately predict speciation under a variety of conditions if the water parameters are well characterized (refs). In particular, it is important to know precisely not just the DOC (Dissolved Organic Carbon), but the percentage of DOC that is humic acid vs. fulvic acid. While both humic acid and fulvic acid complexes diffuse much more slowly than the inorganic form, humic acid complexes diffuse about twice as slowly as fulvic acid complexes. In addition, both acid concentrations have a large impact on the speciation model predictions (Zhang and Davison, 2000). The effect of varying these parameters on the fit of the model to the experimental data will be explored.

This experiment will be done over four lab periods. During the first lab period, the students will set up the water samples with the DGT devices and allow them to incubate until the following laboratory period (48 hours). They will also be introduced to the trace metal analysis equipment (GFAAS and ICP-AES) and will prepare and analyze standards and samples for major cations using ICP-AES. During the second lab period, students will elute the devices and analyze them using the appropriate method. During the third and fourth lab period, the students will utilize the Visual MINTEQ program to calculate the speciation and then compare with the measured results. As part of the laboratory samples, students can explore the effects of pH, dissolved organic content and ionic strength on both the DGT results as well as the agreement between the model calculations and the DGT measurement. Students will also be provided with data from the Principles of Chemistry class on Kd and its variation with the same parameters. The effects both of transport and bioavailability on the ultimate toxicity of a given metal will be discussed.

This experiment will replace two of our current labs designed to expose students to atomic spectroscopy. It will accomplish the same pedagogical goal of teaching students how to prepare samples and standards for atomic analysis, as well as provide them with hands-on experience with the equipment necessary for spectroscopic analyses. Moreover, students will now also learn about ion exchange, metal speciation and the environmental importance of bioavailability.

The environmental chemistry and toxicology course (CHEM 371) is a new course that will be introduced in the spring of 2007. This course will be an upper level chemistry course with a prerequisite of equilibrium and analysis. The expected enrollment will be 10-15 students.Two modules will be developed for this course and those two modules will comprise the entire 14 weeks of the laboratory portion of this course.

As an extension to the work performed in Equilibrium and Analysis, the first module will involve the in situ deployment of DGT devices at both our field site and our remote site. Data on temperature, pH, dissolved organic carbon, alkalinity, as well as major cations (Ca2+, Mg2+, Na+ and K+), major anions (SO42- and Cl-), and sulfide concentrations will be collected for both sites. In addition, further characterization of the dissolved organic content for each site will be performed in order to accurately quantify the amount of humic acid and fulvic acid present (this data will then be provided to the Equilibrium and Analysis course to help in their calculations). For this model, we will deploy several DGT devices, each of them corresponding to a different diffusion layer hydrogel. The data obtained will provide a direct measure of the metal speciation. Visual MINTEQ will also be used to model each metal speciation.

A second module will involve the use of a model organism, Daphnia magna, to monitor toxicity of a metal in various water samples and the use of the biotic ligand model (BLM) to predict toxicity under the same conditions. Toxicity testing with a specific organism is the most accurate method of determining the toxicity of a metal in the environment, but also the most time consuming. The biotic ligand model, which treats the organism of interest as a ligand which is competing for metal binding with the other ligands in the solution, is of great interest because of its ability to greatly simplify the measurement of potential toxicity.

Well characterized water samples from our two test sites, as well as laboratory samples for various metals will be used in the study. Daphnia magna, also called water fleas, are crustaceans commonly used in environmental toxicity studies. These are easy to handle and grow as well as inexpensive. Using these organisms, students will first construct toxicity curves for known metals (Cu, Cd, Zn) in synthetic water solutions with controlled parameters. These studies will then be repeated using water from the three systems described above. The results will then be compared to those predicted by the BLM (ref) to demonstrate the usefulness of such a model as well as help students understand how they are constructed.

biology

Keck-Eco Bio and field module now up with John I's and Bill B's blessing. Amy & Peter are looking at cell phys module now.

The ecological impact of heavy metal pollution at Springwood Lake will be explored through modules within two field biology classes and through summer research. We propose to develop a module for Biology 111, Ecological Biology. This is an introductory level course, with approximately 100 students annually. Non-science majors typically represent 50 to 65% of the class size. Students will help inventory the biota of the lake in a sampling lab, share data, interpret data, and be introduced to population modeling computation. Learning outcomes include: • Gaining an appreciation for the interrelationships and natural history dynamics of ecological communities. • Understanding the importance of quantitative techniques and reasoning in the description and study of complex ecosystems. • Gaining the ability to critically evaluate sampling protocol efficacy and the quality of quantitative data. In this module, each lab group in EcoBio will make a field trip to Springwood Lake and learn aquatic biota sampling techniques. Plants will be sampled manually; invertebrates by plankton tows, nets, and dredges; and vertebrates by seine or fyke nets. Students will work in groups of four or five and each group will gather higher taxon-specific data such as mensural and meristic measurements, age estimations, population density and biomass calculations. Portions of samples will also be preserved for metal analysis by the chemistry department during summer research. Groups will share data and an accurate biotic inventory of the lake will emerge.

This module would be introduced in the Fall of 2007 and continue, allowing us to track changes in populations which will be vital information for assessing the significance of heavy metal pollution at the lake.

Biotic inventory work and food-chain construction will be continued in a module to be developed for Biology 346, Vertebrate Zoology. This is an upper-level course with a typical enrollment of 20-25 students. Learning outcomes for this module include: • Learning the theoretical concepts as well as the field techniques of population ecology of vertebrates. • Learning about vertebrates in aquatic ecosystems and aquatic toxicology and how geology and chemistry are vital to understanding these fields. • Being exposed to the application of contemporary computational methods used in vertebrate population modeling.

In this module, students will use mark-recapture studies (using injection of passive integrated transponders [PIT tags]) to estimate population sizes and standing crop biomass of macrovertebrates (fish and turtles). Gut content analysis (by dissection for invertebrates, and non-destructive stomach flushing of vertebrates) will be used to determine food chains. Blood and/or tissue samples (non-destructive whenever possible) will be saved for analysis of metals during summer research, and these values will be related to the trophic ecology of individual species. We would also do sampling of tissues of these same organisms in other county lakes as reference values for this general region.

This module will be introduced in the Spring of 2008, and repeated annually, with special emphasis on following tagged animals and investigating evidence for bioaccumulation of metals in these animals.

It is predicted that some students involved in this course work will continue to work on the problem in summer research in 2008 and 2009. The above course work will establish the populations and food-chains involved at Springwood Lake, while summer research will focus on the actual analysis of metals in representative organisms from the lake. In addition to samples saved from the course work discussed above, students will re-sample fish and turtles. Some fish will be sacrificed for analysis of metals in specific tissues, specifically gill, liver, kidney and gonad. Metal analyses will be performed by the Earlham chemistry department. Bioaccumulation and biomagnification at higher trophic levels will be assessed. Tissues will also be processed for microscopy and examined for histopathologic evidence of metal intoxication using routine histologic techniques which are currently being used at Earlham.

Do I need to add chemistry’s exact methodology here?

To study cellular responses to metals, a laboratory module will be developed for Biology 341, Cell Physiology. This is a sophomore level course which typically has an enrollment of approximately eighty students. Over the course of the semester, students will investigate the effects of heavy metals on the expression of heat shock proteins in fish red blood cells, explore the chemical and physical variables that effect toxicity of metals in aqueous environments, work with complex data sets and multivariate statistics, and become introduced to bioinformatics.

Learning outcomes will include: • Students will gain an understanding of how cells and organisms respond to heavy metal intoxication. • Students will understand how bioavailability of heavy metals is a function of water characteristics and see how chemistry and hydrogeology play important roles in toxicology. • Students will gain experience in experimental design, multivariate statistics, spectrophotometry, protein quantification, and Western blot analysis. • Students will be introduced to bioinformatics.

Fish red blood cells are an ideal system for studying cellular responses to heavy metals. Because they are nucleated and capable of transcription, translation, and protein synthesis, fish red blood cells are a valuable model for studying cellular responses to a variety of stresses (Currie and Tufts, 1997). Fish red blood cells reliably respond to heavy metal stress by the expression of heat shock proteins (HSPs), and is some cases do so in a graded, dose-dependent manner (Fulladosa, et al, 2006.)

In weeks 1-3 of this lab module, readings and worksheets will introduce students to the concepts of heat shock proteins, models for studying cell physiology, heavy metals and environmental toxicology, aqueous environments from a chemistry and hydrogeology perspective, and protein analysis. After this introductory material, students will help choose what chemical and physical variables to add to the protocol; choosing variables that most closely approximate those found at Springwood Lake that would affect the bioavailability of metals.

Lab groups will be assigned the parameter that they will be testing: controls, metals as stressors, or metals plus chemical or physical variables affecting bioavailability. During this period they will also construct standard curves for protein quantification on spectrophotometers with bovine serum albumin and the Bradford method.

In weeks 4-7, the wet lab will be conducted. We will purchase juvenile or adult rainbow trout, Oncorhynchus mykiss, from a regional supplier. Ideally, the trout will be kept in Earlham aquaria for an aclimitization period of one month. Trout will be anesthetized in buffered 3-aminobenzoic acid ethyl ester (MS-222, Sigma) and blood drawn from the caudal vein. The red blood cells will be separated by centrifugation and then incubated in Hank’s Balanced Salts Solution prepared with known amounts of CdCl2, PbCl2, or K2Cr2O7, either alone or in combination with chemical or physical variables such as nitrates, sulfates, organic matter, anions, acid or alkaline conditions or variable temperatures. Cells will be incubated at 20oC for 2 hours and samples prepared for protein analysis by lysis, centrifugation and supernatant collection. Total protein will be determined by the Bradford method, and gel electrophoresis and Western blot will be used to detect hsp70 using murine anti-hsp70 antibody (Sigma). Students will be able to semi-quantitatively analyze changes in hsp70 expression among the various groups. Groups will share their data with the entire class.

Weeks 8-12 will involve data interpretation and multivariate statistical analysis, as well as the bioinformatics portion of the module. A member of Earlham’s math department will help with the instruction of the multivariate statistics.

The bioinformatics portion of this module will center around the metallothionein family of proteins. Metallothioneins (MTs) are polypeptides, and like heat shock proteins, they are produced in response to metal intoxication in a number of organisms and models, including fish red blood cells (Bauman, et al, 1993.) MTs are known to help protect cells against cadmium toxicity; they bind a variety of metals with abundant cysteine residues, which are highly conserved across phyla (Klaassen, et al, 1999). Students will use Biology Workbench, SwissProt, and ClustalW to construct gene trees and phylogenies using the MT family of genes. They will also explore MT structure, folding, function and molecular evolution using PDB and ConSurf.

The wet lab portion of this module is a modification of the current Cell Physiology laboratory using similar if not identical methods and equipment. In the current lab, students investigate the expression of hsp70 in hemolymph of the tobacco hornmworn, Manduca sextans, as induced by a variety of stressors. This particular module will be developed in the summer of 2007 with summer research students performing all aspects of the lab, including preparation, writing a lab manual, and trouble-shooting. It will be the first time that multivariate statistics and bioinformatics will be taught in this course.

Introductory-Level Course Module-GEOS211 Physical Geology

Physical Geology at Earlham is an introductory-level course that is taken by both science and non-science majors. Students in this course who are non-science majors generally lack confidence in their ability to “do” science and have had little to no exposure to an inquiry-based science classroom. In this course module, students will apply fundamental geologic methods of analysis to an environmental project. By the end of this module, students will be able to:

Use web-based GIS to display and organize data relevant to the characterization of the project site.

Use field and laboratory observations to describe the geology of the project site.

Organize and analyze geochemical data to display the concentration distribution of heavy metals in lake bottom sediments at the project site.

Establish a chronology of heavy metal loading to the project basin via interpretation of heavy metal stratigraphy.

Create a scientific report synthesizing the results of the project and suggesting areas for further study.

Upon completion of the project, selected students will present results to other introductory-level students participating in courses with applied modules. All students will then be required to write a report describing the different approaches and results each of these courses takes in studying this environmental problem.

This module will use the final four laboratory sessions in Physical Geology. Students will have a basic background in geology and will be able to apply that knowledge to the local area. Each laboratory section has a maximum of twenty-two students, with one professor and one upper-level undergraduate teaching assistant.

Week One: Readings and worksheets will focus on the general problem of metals in the environment with emphasis on lake sediments as pollutant archives. Readings will be keyed to discussions of the hydrologic cycle with an emphasis placed on the connection between groundwater flow and subsurface geology. Students will begin to learn how to use web-based GIS to create displays of the study area.

Week Two: Field trip to the project site. Students will examine the geology and hydrology of the project site (Springwood Lake) and participate in a demonstration of sampling a sediment core from the lake.

Week Three: In teams, students will observe and describe a suite of sediment cores to determine terms of sediment composition, texture, color, sorting, fabric and sedimentological characteristics.

Week Four: Students will be given geochemical data keyed to the cores described in Week Three (geochemical data will have been collected by upper-level geochemistry students or will have been collected as part of a summer research project). Students will be required to plot and analyze this data and make interpretations about the concentrations of heavy metals in Springwood Lake over time as a result of their analysis. Students will then write a full scientific report of this project and share the results with other introductory-level science students working on different aspects of this project.

Upper-Level Course Module: GEOS 362 Hydrogeology

Hydrogeology at Earlham is taught with an emphasis on practical application of theoretical concepts. Two course modules will be developed for hydrogeology; one each for each of the project sites. These course modules will enrich student comprehension of the significance of ground water/surface water interaction in the vicinity of the project sites and will develop student capabilities for collecting, analyzing, displaying and interpreting ground water data.

At the on-campus field site, students will be active participants in designing, installing and managing data collection from ground water monitoring devices. instrumentation instrumenting the

At the conclusion of these modules students will be able to:

• Evaluate data collection requirements (number and spacing of piezometers, monitoring wells)Prepare geologic and hydrostratigraphic unit cross-sections from well-boring data.

• Obtain laboratory measurements of whole soil porosity for each hydrostratigraphic layer at each of the project sites.

• Collect, tabulate and display ground water elevation data and prepare detailed maps of potentiometric surfaces.

• Determine horizontal hydraulic conductivity values for saturaed media at each project area.

• Computationally analyze potentiometric, porosity and permeability data to calculate rates of ground water flow and formulate predictions of ground water flow behavior.

mathematics

Math 120, Elementary Statistics, is a general education course taught each semester in which students are introduced to the key notions of statistics: descriptive statistics and inference testing. We will make use of the "metals in the environment" data sets in teaching students how to do typical tasks of descriptive statistics: measures of central tendency, measures of dispersion, and construction and interpretation of graphical displays of statistical information (univariate and bivariate data). Use of data sets from Springwood Lake and our back-campus field site will help students grasp the differences in origin and potential uses between observational and experimental data. Probably the greatest advantage of using this data is that it will be "real" to the students. They will know the sites (and potentially the historical context of those sites) where the data is collected, and the students involved in the experimental design and data collection.

Math 300, Statistics, is a calculus-based introductory course which we teach every other fall semester. We would make similar use of the data sets as for Math 120.

EnPr 242, Environmental Models, is taught each fall and is required for all students who are earning a major or a minor in either environmental science or environmental studies. This course is taught by a mathematics professor and includes application modules involving biology, chemistry, computer science, geology, and mathematics. The "metals in the environment" data will be used with the module on the chemistry of hazardous materials. The wells at the backcampus site will provide data that will be very useful for the module which introduces the organization, analysis and interpolation of scatted spatial data. And the aquatic biota population data from Springwood Lake will be integrated into the population biology module. As with statistics courses, the use of Earlham-related data will motivate students in their use of linear algebra and geometry to model environmental situations.

6) Technical problems that may be encountered and how they will be addressed.

Two aspects, multi-disciplinary, computational, pedagogy and then all the science. Almost all of the individual pieces have been deployed elsewhere, we are adapting and refining them...

Description

9) Description of facilities, equipment and resources available for the project.

The science complex at Earlham consists of three interconnected buildings, Dennis Hall (Computer Science, Geology, Physics, and Mathematics), Noyes Hall (Science Library, large computer lab) and Stanley Hall (Biology and Chemistry) with a net square footage of 76,000. .

The laboratory portion of the chemistry modules will utilize two laboratories (one for general chemistry/equilibrium and analysis and a separate lab for environmental chemistry). These labs have a total square footage of 2950 (1719 for gen chem, 1230 for p chem) and a combined total of 11 hoods and each lab has benchspace for approximately 20 students.

Analysis of metals will be conducted on two separate instruments: an inductively coupled atomic emission spectrometer (ICP-AES) and a combination flame/graphite furnace atomic absorption spectrometer (GFAAS). The ICP-AES (Perkin Elmer Optima 4100DV) is a dual view, multielement analyzer capable of analyzing up to 50 elements in under a minute. We have also recently installed an ultrasonic nebulizer (CETAC U-5000-AT), which will increase our sensitivity by a factor of 10. The GFAAS (Perkin Elmer AAnalyst 800) is a state of the art transverse heated graphite tube system with Zeeman background correction. This instrument will be utilized in GFAAS mode to analyze metals when the detection limits of ICP-AES are insufficient for the levels present in our samples. It will be utilized in flame mode when analyzing major elements such as calcium or magnesium. Both instruments are fully automated (allowing the analysis to continue even after the 3 hour lab has ended) and utilize the same software platform (which will simplify student training).

Prior to analysis by the methods listed above, solid samples must be converted into a homogenous aqueous form. Our current microwave digestion system (CEM MDS-2000) has both temperature and pressure control and will be useful in method development for digestion protocols. It is, however, limited in sample throughput to 12 vessels.

Three different biology teaching laboratories will be used for the course modules. Each lab is approximately 1200 square feet, with bench space for 24 students. Equipment to be used includes dissecting microscopes, compound micrscopes, spectrophotometers, UV pectrophotometers, mini-mrotein gel electrophoresis units, mini trans-blot cells, microcentrifuge, 6 computer stations for statistical analysis, E-gel units, refrigerators, ultra-low freezer, and environmental chambers. Summer research in biology will be conducted in the faculty research area which is 1500 square feet. Additional equipment for this research will include microtome, a cryotome to arrive...., flourescent microscopes.

The Computer Science department maintains file servers, compute servers, web servers, database servers, and three modest 16 node Beowulf clusters which are used for the development and testing of computational science curriculum modules, the teaching of parallel and distributed programming, and student/faculty research projects (see http://cluster.earlham.edu). This infrastructure is managed by a student/faculty applied computer science group, the System and Network Administrators (see http://cs.earlham.edu). The Hardware Interfacing Project, another student/faculty applied computer science group, has designed and developed a variety of field-deployable computing equipment. This includes stand-alone weather and energy monitoring systems. Computing Services at Earlham College maintains multiple Internet links for college-wide use.

10) Equipment requests should:

• Describe comparable equipment already at the institution and explain why it cannot be used.
• Explain if the new equipment will be available to support other efforts and how time will be allocated on it.
• Describe plans for facility operations and maintenance.

Large freeze dryer – There is currently one small freeze-dryer that would be available for this project. Given the large number of soil, plant, and biological samples that will be processed for this project, there is a need for a high capacity freeze dryer. The model we have requested will include bulk drying trays and a large capacity.

Acid digestion system - There is currently one microwave digestion system. Digestion of solid samples will likely be one of the bottlenecks in the analysis of samples by our atomic spectroscopy equipment. The instrument that we propose to purchase will be a CEM MARSxpress system with a high throughput capacity (40 sample tray).

Atomic Absorption Spectrometer (AAnalyst 800) and Spectroscopy supplies. Recently we have purchased an AAnalyst 800 combination graphite furnace and flame atomic absorption spectromter. We will need to purchase additional lamps and other supplies to utilize this instrument for the wide array of metals that we propose to analyze.

Semi-automated Total Organic Content Analyzer - for the more sophistocated fate and transport models as well as the biotic ligand model, it is imperative to know the dissolved organic content. We do not currently have this capability.

Differential GPS

Field monitoring eqpmnt (Temperature, pH (digital), conductivity, redox (reduction oxidation potential), pressure transducer, nitrate selective probe, computer, packaging, and communications)

Field Sampling Kits (Lake sediment cores to 2 m, Shelby soil cores, Monitoring wells (one time install), Drawing equipment)

Biology sampling gear (Nets (ten 50’ fyke nets @ $300 each; Nichols Net and Twine), Containers: Rubbermaid fiberclass stackable tubs (10 @ $30), Passive Integrated Transponder (PIT) tags (250 @$7) and reader (InfoPet))

11) Plans for this project beyond the proposed time period, including financial support.

We request that WMKF, with institutional support from the College, fund this pilot project. The College has committed $167,049 in resources as start-up funding. We are embarking on a capital campaign that includes a goal of building a $3 million endowment for science faculty/student research. We believe that a WMKF investment will serve as a catalyst for major gifts from alumni, friends, corporations and other foundations.

12) Describe how the success of the project will be evaluated in terms of the goals proposed. Include information regarding outside review committees, if appropriate.

• Evaluation Team: We have identified several possible sources of both internal and external evaluation. Internal evaluations will be conducted by one or more members of the project and other faculty and staff within the science division who are not directly involved in developing or using these curricular modules. External evaluators will be drawn from program assessors who have worked previously with Earlham College and/or from organizations which provide consultancy services such as the Council on Undergraduate Research (CUR). CUR can provide program evaluation sensitive to issues at predominantly undergraduate institutions including evaluators with experience in evaluating interdisciplinary and interdepartmental programs.

• Timing: Evaluation of the Keck program will occur both during (formative) and at the end (summative) of the grant period. The formative process evaluations conducted at various points throughout the grant period will assist the faculty and academic departments involved in this interdisciplinary project to refine the project goals and objectives and to make any ongoing modifications or revisions. They will identify what is working during the initial implementation and point to areas needing further development. The summative evaluation will take place at the end of the grant period and will provide a measure of how well the program goals were met as well as provide directions for future growth.

• Goals: The project leaders will meet with the evaluators to clarify, operationalize, and select and development instruments which evaluate the stated and implicit goals of the project (above). The project evaluators will also help to conceptualize key issues or problems that would keep our program from meeting our stated objectives and specify particular criteria for success as well as identify particular data needed to determine how well the components of the program are meeting their objectives.

• Methods: Delineating project goals will assist us in developing both qualitative and quantitative measures for determining how well our goals are being met during both the formative and summative evaluation phase. Qualitative evaluations will include:
  • Open-ended surveys: The evaluator will collect answers without preset response categories to written questions. Surveys with an open-ended component would be given to all students enrolled in courses where a research-based interdisciplinary module was used, faculty who developed and taught such courses, and participants in any workshops in which the faculty involved in the Keck program presented the pedagogy and organization of this project.
  • Semi-structured interviews: The evaluator will conduct semi-structured interviews of key personnel and a representative sample of students to allow the evaluator some first hand experience with the evaluated activities and a chance for in-depth exploration of particular issues.
  • Peer evaluation: Efforts at developing interdisciplinary course modules incorporating computational modeling will be described in peer-reviewed publications providing feedback from the reviewers as well as others who read the articles.

Quantitative evaluations will include:

• • Quantitative surveys: Quantitative pre and post surveys of student or workshop participant attitudes toward and confidence in computational methodology, interdisciplinary collaboration, relevance of environmental studies in particular disciplines, and interest in science and society.
  • Institutional data: Assessment of pre and post grant levels of student participation in undergraduate research, likelihood of taking a secod science class, and number of science majors.
  • Incorporation in curriculum: Measurement of the pre and post grant percentages of incorporation of computational modeling in primarily field or laboratory based courses and field or laboratory modeling in computational courses.
  • Incorporation in co-curriculum: Comparison of the numbers pre and post grant interdisciplinary projects including collaborative research projects and grant writing efforts.

• Results: Final reports summarizing both the quantitative and qualitative data will be produced. They will asses which and to what degree goals have been met for affected students, faculty, and the institution as a whole as well as provide recommendations for further implantation and dissemination.

Dissemination activities will include:

• • NITLE workshop on integrating multi-disciplinary computational methods into the undergraduate science curriculum.
  • Earlham Science Poster Session
  • Student papers at Butler
  • CUR (Earlham is a member now)
  • Student/Faculty papers in science pedagogy journals?

2. State the number of students (undergrad/grad/postdoc), research associates or technicians to be supported and number of years of support.

The project will support summer research for approximately 12 students each summer for 3 years.

3. Explain why W. M. Keck Foundation support is essential for this project.

Funding for undergraduate research at small, liberal arts colleges is limited. The WMKF is known and respected throughout the scientific community as a foundation that supports innovative science programs at high-quality undergraduate institutions. WMKF funding would allow Earlham to launch its multidisciplinary science project. Keck support would also raise the visibility of the sciences within the College and with external audiences regionally and nationally.

4. List all current and pending federal and non-federal support, including institutional or departmental funding, related to this project.

Earlham College will provide $167,000 specifically toward this project. There is no other pending funding. However, with the leverage and prestige that a Keck grant will provide, we believe that we will be well-positioned to solicit major gifts (both for current use and for an endowed student/faculty research fund) for continuation and expansion of multidisciplinary science projects, as well as submission of proposals for future funding to NSF and other private foundations.

5. If construction or remodeling is involved, provide a copy of the permits required or an explanation of how and when the permits will be acquired.

There are no construction or remodeling components of this proposal.

6) Recognition Statement

• Describe the manner in which the institution will recognize and acknowledge a W. M. Keck Foundation grant for this project.

Earlham College science faculty and public information staff will work closely with the W.M. Keck Foundation to publicize grant funding. Upon approval of text, Earlham's public information staff will distribute news releases to local, regional and national media, and to educational publications such as the Chronicle on Higher Education to announce receipt of a Keck grant.
