Quantifying Groundwater Baseflow and Improving Math Skills through a Stream-Discharge Exercise
James Reichard, Georgia Southern University
A two-part exercise is presented where students quantify stream discharge and use the data to determine groundwater baseflow. They first use tedious hand calculations to compute discharge; then develop their own ...

Assessing the error of linear and planar field data using Fisher statistics
Vince Cronin, Baylor University
Instruction on use of Fisher statistics to determine the mean and 95% confidence interval of geological vectors, lines or planes, with examples, problems and an Excel spreadsheet for computation.
Prework for Rivers and Streams Lab (Intro Geology)
Rachel Teasdale, California State University-Chico
In order to give Introductory Geology (Physical Geology) undergraduate non-majors students experience and confidence in using basic algebra to calculate very simple stream flow properties, we use a prework assignment prior to the Rivers and Streams Lab. Prework is a worksheet assigned 2 weeks in advance, which asks students to calculate velocity and discharge as well as unit conversions and calculations of stream load. The questions are put into the context of activities they completed earlier in the semester during visits to the stream (on campus) so questions are relevant to their previous experiences. The prework timeframe gives students the opportunity to seek extra help from their instructor prior to the lab period in which they will make additional measurements, similar calcualations and interpretations of their data.
Discharge and Sediment Transport in the Field
Jeff Clark, Lawrence University
In this quantitative field activity, students collect field data on channel geometry, flow velocity, and bed materials. Using these data, they apply flow resistance equations and sediment transport relations to estimate the bankfull discharge and to determine if the flow is sufficient to mobilize the bed.
Class discussions and field trips
Jiang Li, Morgan State University
Here we see it, but what's beneath? Effective geologic cross-section problem solving
Rob Benson, Adams State College
Students will use suface observations from a map to locate subsurface features using geologic cross-sections using topographic profiles, surface data, assessment of variables and data quality. Students will produce a standard scientific report describing the nature and conclusions of the project.
Water Quality Acquisition
Students practice their field water sample collection and water quality assessment skills and study acid mine drainage.
Measuring the Campus Green
Paul Vincent, Valdosta State University
Students use basic tools to measure the size of one-quarter acre.
Investigating Flight with Paper Airplanes
Ellen Gevers Lincoln Elementary White Bear Lake MN
Students will determine a testable question and create an experiment related to flight of paper airplanes. They will gather and record data and present their findings to classmates.
