Florida River Project - individual and group research project
Outcomes of the individual project include:
- Practice applying the process of science
- Graphing and interpreting data
- Making an argument supported by quantitative evidence.
- Communicating a scientific argument in writing.
- Supporting a scientific argument using appropriate formats (especially graphs and tables)
Outcomes of the group project include:
- Collecting field data (discharge, sediment load, water chemistry)
- Presenting data orally.
- Discussing preliminary interpretations of data.
Skills and concepts that students must have mastered
The Math You Need, When You Need It (http://serc.carleton.edu/mathyouneed/index.html) is used to support math skills (including reading graphs and unit conversions) in labs associated with this assignment.

Description and Teaching Materials
The project is designed to(1) support college-wide quantitative skills learning outcomes, (2) engage students in the process of science, (3) promote students' sense of ownership of their research project, (4) collect data in the field, and (5) present data in writing and orally.
In the individual project, students develop the skills needed to make an argument supported by quantitative data. The individual project consists of four components: two graphing exercises (to develop skills necessary to use data to answer questions), the proposal of a question, and a final paper in which students use previously collected data to address their question.
In the group project, students work in groups of 4 to 6 students to collect and present data. Each group is responsible for collecting a particular type of data during a field lab (discharge, sediment load, or water chemistry). Each lab section monitors a different site (out of nine possibilities) along the Florida River. The group work is divided into three components: (1) a short background paper discussing the type of data to be collected; (2) data collection in the field; and (3) an informal presentation of the data to the class (modeled after research group meetings, rather than conference presentations).

Teaching Notes and Tips
1) Graphing with Excel is complicated by the differences between Mac and PC versions of the software, and by the changes that arise in each new edition of the software. Frustration with the software (and with computers in general) is a major barrier to student learning in this exercise.
2) It is difficult to break students' attachment to the simplistic Scientific Method that they learned before college. It is necessary to provide feedback about appropriate research questions at many points throughout the semester; otherwise, many students revert to proposing hypotheses like "the river will have 80 cfs on March 10," and "the discharge was 90 cfs; the hypothesis failed."
3) Writing a paper based on data (rather than on library research) is unfamiliar to students in an introductory science class, especially if they have taken college-level writing courses outside the sciences. It helps to give students opportunities to discuss their paper with the professor (or with a teaching assistant). However, these meetings are very time-intensive.
