Assessing the error of linear and planar field data using Fisher statistics part of Quantitative Skills:Activity Collection
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.

Discharge and Sediment Transport in the Field part of Quantitative Skills:Activity Collection
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.

Prework for Rivers and Streams Lab (Intro Geology) part of Quantitative Skills:Activity Collection
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.

Water Quality Acquisition part of Quantitative Skills:Activity Collection
Ming-Kuo Lee
Students practice their field water sample collection and water quality assessment skills and study acid mine drainage.

Here we see it, but what's beneath? Effective geologic cross-section problem solving part of Quantitative Skills:Activity Collection
Rob Benson, Adams State University
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.
